A solar pool cover is a floating sheet of UV-resistant polyethylene that sits on your pool and does one job: hold heat in the water. For an inground pool, that job matters more than most owners expect, because the largest single source of heat loss from a pool is evaporation, and a cover cuts that by up to 95 percent. The right pick for a 16×32 rectangle is not the same as the right pick for an 18×36 kidney, so below I compared ten covers across mil thickness, construction, weight and the durability complaints owners actually report.
One thing to say before the list: a solar bubble cover is a thermal tool, not a heater and not a safety cover. It cannot raise water temperature on its own in the way a heat pump does, and no child should ever be allowed on one. If you want warmth from the sun, you are looking at pool heat pumps or solar pool heaters to run alongside it.
We spent 2026 season reading owner reviews, comparing spec sheets and checking the failure patterns that show up in the long review tails, because that is where the useful information lives. Every product below is a floating bubble blanket sold for inground pools, and every rating and review count is copied straight from the listing data rather than rounded or estimated.
Top 3 Best Solar Pool Covers for Inground Pools in October
BigXwell 16 Mil 16×32 Cover
- 16 mil polyethylene
- Trims with scissors
- Cuts evaporation up to 95 percent
Those three are the covers we would put on our own decks first. The BigXwell 16 mil is the most balanced choice on the list: thick enough to sit heavily on the water, light enough for one person to wrestle onto a 16×32, and backed by more than a thousand reviews. The VEVOR is the value version of the same idea, and the Real Relax is the one with the strongest single rating in the group, though its review history is much shorter.

What a Solar Pool Cover Actually Does (and What It Cannot Do)
The honest answer is that a solar cover is a heat retention tool with a small bonus of solar gain, and most confusion comes from mixing those two jobs together. The polyethylene film is thin enough that short-wave sunlight passes through and warms the water underneath, while the sealed air bubbles on the underside slow convective and evaporative loss once the sun goes down. The retention part is the reliable, repeatable part of the equation.
That is also why the wildly different temperature numbers you will see online are not necessarily dishonest. A “4 degree” claim is usually an overnight retention figure: the difference between your morning reading with the cover and without it. A “15 degree” figure is a multi-day cumulative gain claim under strong sun, like the 8 to 15 degrees Celsius range VEVOR advertises, or the 14 to 27 degrees Fahrenheit Goplus lists. Both are describing the same sheet of plastic measured over different windows of time.
Our read of the owner data is that the honest expectation for a well-fitted cover is a water temperature that holds steady overnight and through cloudy days, plus a slower climb on sunny afternoons. Several 16 mil covers in this roundup consistently lose only about 5 degrees Fahrenheit on cold winter nights, which is the number owners who live with the cover quote most often.
Two limits worth stating plainly. A solar cover does not generate meaningful heat in cold weather, and on days when the air temperature is well above the water temperature the cover can actually slow your warming slightly. It also does nothing to make the pool safe. Every cover in this list is a floating film that a child can slip under and drown behind, and the look of it deceives people, which is why it belongs in a FAQ as its own question.
1. BigXwell Heavy-Duty 16 Mil Solar Pool Cover 16×32 – Our Overall Pick
BigXwell Heavy-Duty Solar Pool Cover 16x32ft – 16Mil Blue
16 mil blue PE
384 inch L x 192 inch W
Floating, thermal
Cuts to any shape
Pros
- 16 mil thickness holds heat overnight
- owners report about 5 degrees Fahrenheit loss on cold winter nights
- Cuts cleanly with scissors without fraying
- Doubles as a debris barrier that cuts vacuuming and chemical use
Cons
- Large sheet needs two people to unroll on medium and large pools
- Needs a roller or reel for daily use
- Stiff material takes effort to position on the water
This is the cover we kept coming back to. It is 16 mil blue polyethylene measuring 384 by 192 inches, the standard footprint for a 16×32 inground rectangle, and it ranks at number 149 in Pool Safety Covers with 1,035 ratings behind it. That combination of thickness and review volume is rare in this category, where most listings sit in the low thousands or under a few hundred.
Owners consistently report the same behaviour: the cover goes on, the water holds its temperature overnight, and it comes off in the morning without having pooled water under a corner. Several buyers mention repeat purchases, which is the tell that a cover is doing its job rather than just blocking leaves.
Heat retention is the headline here. Reviewers describe losses of roughly 5 degrees Fahrenheit on genuinely cold winter nights, which is a good outcome for a floating film with no insulation rating attached to it. The 16 mil weight is what makes that possible, because thicker polyethylene sits down on the surface instead of riding up on the waves.
The cutting behaviour matters more than the spec sheet implies. Multiple buyers say the material trims with ordinary scissors without tearing or fraying the edge, and because the film is PE, a cut edge will not unravel the way a woven fabric would. The listing also notes the cover suits inground or above-ground pools, so the same sheet works if your plans change.
What you have to plan for before buying
This is a 16 by 32 sheet, so measure your pool before you order anything. It is listed as floating, meaning it stays on the water by its own weight, which is the reason it needs a reel for daily use.
Two people is the realistic number for unrolling it across a deck. Owners on medium and larger pools describe it as a genuinely two-person job, so if you are handling it alone every morning, budget for a roller or a reel instead of straining your back on the corner.
Where the complaints actually come from
The most common friction is handling stiffness. The material is firm enough to hold a flat plane on the water but firm enough to fight you while you are spreading it, and reviewers say it takes deliberate effort to position. That is a technique issue rather than a defect, and it improves once you start at the shallow end and walk the sheet forward.
A small number of buyers report that a size received was larger than ordered and needed cutting down, which is a listing accuracy problem rather than a product one. One reviewer reported exactly that with a round size, so measure twice and be ready to trim.
2. Real Relax 16 Mil Solar Pool Cover 16×32 – Highest Rated in the Group
Real Relax 16 mil Solar Pool Cover, 16 x 32 ft Rectangle Bubble Blanket
16 mil blue PE
32 ft x 16 ft rectangle
39 pounds
Bubble side down
Pros
- Highest average rating in this roundup at 4.7 stars
- Absorbs solar heat and holds water warm overnight
- Keeps leaves and debris out of the water
- Trims to any pool shape with ordinary scissors
Cons
- Short review history at 129 ratings
- Long-term durability is less well documented
- Must be installed bubble side down
The Real Relax earns the highest average rating in this roundup at 4.7 stars, with 81 percent of ratings at five stars. It is a 16 mil polyethylene bubble blanket in a 32 by 16 foot rectangle, weighing 39 pounds, and it is one of only three 16 mil covers in the group alongside the BigXwell and the VEVOR.
What draws praise is straightforward: the sheet absorbs heat during the day, the water stays warm overnight, and it keeps debris out. Buyers also call out how easily it trims, which is a bigger deal for kidney and freeform pools than for rectangles.
Installation direction is the one detail that trips people up. The bubbles must face down toward the water for heat transfer to work, and getting it on flat-side-down does nothing useful. The care instructions are minimal: rinse off debris and store it when not in use.
Evaporation reduction is listed at up to 95 percent, in line with the rest of the category. That figure is a measured maximum under test conditions rather than a daily average, but even a partial reduction is the reason these covers pay for themselves in a single season in most climates.
Whether the thin review history matters to you
With 129 ratings, this is the least proven listing here, and that matters if you are buying for a ten-year service life rather than a couple of seasons. The category leaders in this roundup carry review counts in the thousands, which tells you a lot more about what happens in year three.
If you want the best evidence, cross-check the owner photos and reports against one of the high-volume 16 mil options. The heating behaviour reported here is consistent with what the better-documented covers do, so we expect the long-run experience to match.
Who should look elsewhere
Buy a 12 mil option instead if weight is your constraint, since 39 pounds is meaningful on a wet deck. A lighter sheet at 12 mil is easier for one person to lift and dry, at the cost of some thickness and durability.
Skip this one if you want a long warranty behind the product. There is no stated warranty period in the listing data, and that is a real difference from covers that carry five or seven year limited terms.
3. VEVOR 16 Mil Solar Pool Cover 32×16 – Top Rated at 16 Mil
VEVOR Solar Pool Cover 32 x 16 ft, 16 Mil Rectangle Solar Blanket Blue
16 mil blue PE
32 ft x 16 ft rectangle
37.8 pounds
Foldable
Pros
- Best category rank in this group at number 28 in Pool Safety Covers
- 16 mil material resists tearing and holds up under prolonged sun
- Trims to any pool shape and blocks leaves and dust
- Low cost for a 16 mil sheet
Cons
- Highest one-star share among the well-reviewed options at about 8 percent
- 37.8 pounds is heavy to handle without a reel
- Bulky folded sheet takes effort to store
VEVOR is the pick if you want 16 mil thickness without paying the premium tier’s money. It holds 1,276 ratings at 4.3 stars and sits at number 28 in Pool Safety Covers, the strongest category rank of anything in this roundup. Owners in pool forums consistently single this brand out as a step up from the thin cover that ships with a new pool kit.
The specification is a 32 by 16 foot rectangle in 16 mil polyethylene, with the bubble film facing down. It is listed as foldable, listed as UV resistant in practice, and the care notes ask for a soft brush and mild detergent with no harsh chemicals.
The heating claim is the boldest in the group at 8 to 15 degrees Celsius depending on conditions, and the evaporation claim is the standard up to 95 percent. Treat both as multi-day sunny-weather outcomes rather than anything you should expect from a single afternoon, which is the same caveat we would apply to every number in this category.
Tensile and tear resistance is where the 16 mil thickness earns its keep. Owners report the film resists fading and warping under prolonged sun, which matters in high-desert installs where a dark blue sheet takes a beating from UV all season.
How the VEVOR handles in wind and sun
At 37.8 pounds the sheet has enough mass to sit down on the water rather than billow, which is the first line of defence against wind lift. That said, no bubble cover in this roundup is windproof, and none of them should be left unattended in a forecast gale.
The durability reports are the weak spot. A small but real share of buyers say the material degrades faster than expected under strong sun, and the one-star share runs around 8 percent, the highest among the options that still carry four-plus averages.
Best fit and who should skip it
This is the right choice for a 16×32 inground rectangle where you want a thick sheet on a tighter budget. The material trims to any shape, so it also works for a freeform if you are willing to spend a Sunday cutting it.
Look at a 12 mil cover if you plan to put the cover on and take it off by yourself every single day. Heavier covers and daily handling do not mix well, and a wet 16 mil sheet at nearly 38 pounds is a two-person job on anything but a small pool.
4. Blue Wave 12 Mil Solar Pool Cover 16×32 – Best for Cutting Chemical Use
Blue Wave 16×32-ft Rectangle Solar Pool Cover 12-Mil Blue – Solar Cover for Above Ground Pool & Inground Pool, Thermal Bubble Blanket for Heat Retention & Reduced Evaporation
12 mil blue plastic
32 ft x 16 ft rectangle
27 pounds
5 year limited warranty
Pros
- Largest review count among 12 mil options here at 2510 ratings
- Owners report lower chlorine consumption with the cover on
- Blocks leaves and debris and deters critters
- Cuts easily to fit kidney and irregular pools
Cons
- Repeated reports of bubbles breaking down after a season
- Warranty is heavily prorated in later years
- 12 mil is thinner and tears more easily than 16 mil
Blue Wave is a 12 mil blue plastic cover in a 32 by 16 foot rectangle, weighing 27 pounds, and it carries 2,510 ratings. That is the biggest review base of any 12 mil option in this roundup, which makes it the safest pick in the thinner tier if you want evidence rather than promises.
The selling point is chemical consumption. Owners report a noticeable drop in chlorine use once the cover is on, which follows from the same physics as the heat savings: less evaporation means less water volume lost, less water lost means less chemical going out of the pool. Several buyers also use it as a critter deterrent between uses.
Construction is 12 mil with downward-facing air-filled thermal bubbles, and the blue colour is specified for overnight heat retention. It is a floating cover, lightweight enough that most owners handle it single-handed, and it is listed as UV resistant and foldable.
One thing to check when the box arrives: the included component is listed as a 16 by 36 foot solar blanket, so the shipped sheet is larger than the 512 square feet the size line implies. That is useful news for a freeform or kidney pool, since you can trim the extra material away.
Reading the warranty honestly
Blue Wave Products backs this with a 5 year limited manufacturer warranty, which sounds generous until you read the reviews about how it is prorated. Buyers report that most of the cost lands in the later years, so effectively this is a two-to-three year cover with paperwork.
The bubble disintegration reports are the other recurring theme. Owners describe the bubbles breaking down after about a season, leaving blue plastic fragments in the pool and in the filter. Plan on vacuuming the bottom after the first summer.
Sizing advice and shrinkage
Leave material before you make the final cut. This cover can shrink slightly after first use, and buyers who trim tight end up with a gap that lets evaporation straight through at the edges.
It is also the easiest of the 12 mil options to cut for an irregular shape, so this is a reasonable choice for a kidney or freeform inground pool where a rectangle will not do. Keep a reel nearby anyway, since 27 pounds gets heavy when wet.
5. In The Swim 12 Mil Premium Solar Blanket 16×32 – Longest Warranty
in The Swim 16 x 32 Foot Rectangle Premium Pool Solar Blanket Cover 12 Mil
12 mil blue PE
384 inch L x 192 inch W
Floating install
Model 1632D
Pros
- 7 year manufacturer limited warranty
- longest stated term in this group
- Claimed 8 to 10 degree gain in 5 to 7 days of consistent sun
- Lightweight polyethylene that is easy to put on and take off
Cons
- 12 mil sits lighter on the water than a 16 mil sheet
- This listing is sold in a single 32 by 16 foot size
- Modest category rank compared with higher volume covers
The In The Swim Premium blanket is the odd one out in this roundup on paper, because it carries a 7 year manufacturer limited warranty while everything else tops out at 5 years or has no stated term at all. That matters more than the rating, because in a category where covers are replaced every few seasons, a long warranty is the closest thing to a durability guarantee you will find.
It is a 12 mil blue polyethylene cover in a 32 by 16 foot rectangle, 384 by 192 inches, made by Midsol under model 1632D. It is floating, lightweight, and rated at 1,105 reviews with a 4.1 star average.
The claimed heating result is up to 8 to 10 degrees in roughly five to seven days of consistent sunlight, which is the most conservative and therefore most believable claim in this group. It also reduces evaporation and chemical loss, and blocks debris entry.
What the warranty does and does not cover
A 7 year limited warranty is a manufacturing defect term, not a promise that the bubbles will last 7 years. No one in this category delivers that, and you should treat any cover as a three-season consumable at most regardless of the paperwork.
Still, if bubbles do fail early through a defect rather than ordinary UV ageing, a long term gives you a route to a replacement. That is meaningfully better than the prorated terms on some competitors.
Where the 12 mil tier shows its age
Owners confirm the heating gain and praise how light the sheet is for daily handling, which is the strongest argument for the 12 mil tier. The trade-off is that it does not sit as heavily on the water as a 16 mil sheet, so it can shift and bunch more easily on a windy afternoon.
Check your size before ordering. This particular listing is a single 32 by 16 foot configuration, so if your pool is 18×36 you will need a different variant entirely. The 12 mil thickness also needs trimming and will not drape as heavily, so avoid cutting it too tight.
6. VINGLI 12 Mil Solar Pool Cover 18×36 – Best for Large Inground Pools
VINGLI 18x36ft Solar Pool Cover 12mil Rectangle Blue
12 mil blue PE
36 ft x 18 ft rectangle
19.87 kg
Model PC-B-18
Pros
- Explicitly marketed for inground pools
- Welded seams for longer service life
- Cuts to irregular and freeform shapes
- Good option in the larger 18 by 36 footprint
Cons
- 12 mil is lighter against the 16 mil options
- Nearly 44 pounds means a reel is effectively required
- Bubbles can look deflated before sun exposure
The VINGLI is one of only two covers here at 18 by 36 feet, which makes it a direct fit for larger inground rectangles and freeforms that a 16 by 32 sheet will not reach. It is 12 mil polyethylene, model PC-B-18, rated at 4.3 stars across 806 reviews.
Its distinguishing feature is the welded seams. Rather than a heat-sealed or adhesive join, the seams are welded, and owners treat that as the reason the cover lasts longer than cheaper 12 mil sheets they have replaced before. The listing also notes that bubbles may appear slightly deflated before sun exposure because of thermal expansion and contraction, which is normal rather than a defect.
It is explicitly marketed for inground pools, which sounds redundant and is not, because plenty of covers in this category are quietly aimed at above-ground frames. The range also includes clear and blue variants in round, oval and rectangular shapes, so the same brand covers most pool geometry.
Cutting guidance is specific and sensible: the listing recommends leaving 2 inches of extra material when trimming to shape. That margin is what stops the edge from sitting short once the film relaxes on the water over a season.
Handling a cover this size on a daily basis
At 19.87 kilograms, roughly 44 pounds, this is one of the heavier sheets in the roundup. Buyers are commonly advised to pair it with a cover reel, and on a pool this size that advice is not optional. Without a reel you are dragging a wet 18×36 sheet across the deck every morning.
On the positive side, a heavier sheet has more mass on the water, which makes it marginally better at resisting wind lift than a 12 mil sheet on a smaller pool. Weight and wind resistance trade against each other against handling convenience.
Who this is the wrong pick for
If you want maximum service life, the 16 mil sheets in this roundup are the better bet, because the 12 mil tier is where the bubble breakdown complaints cluster. The VINGLI counters that with welded seams, but it does not change the base film thickness.
It is also the wrong choice for a small pool or a hot tub, where an 18×36 sheet is pure excess. Match the footprint to the pool and let the thickness decision be your second choice.
7. Goplus 12 Mil Solar Blanket 12×24 – Budget Pick for Smaller Pools
Goplus Solar Pool Cover, 12 x 24 FT Solar Blanket 12 Mil with Carrying Bag for In-Ground and Above-Ground Swimming Pools, Rectangle Hot Tub SPA Thermal Blanket, Blue Bubble
12 mil blue PE
24 ft x 12 ft rectangle
Small dense bubbles
Carrying bag included
Pros
- Lowest cost per square foot in this roundup
- Owners log morning water temperature jumps of 5 degrees or more
- Cuts very easily even to kidney shapes
- Carrying bag makes storage simple
Cons
- Several buyers report material degrading within a season
- Light sheet shifts and bunches if not weighted
- Anchoring bags may arrive damaged
The Goplus is the value entry point in this roundup and the only one sized for a small to mid-size pool, at 12 by 24 feet. It is 12 mil polyethylene with small, dense bubbles, rated 4.2 stars across 414 reviews, and it includes a zip-up carrying bag with handles.
The dense micro-style bubble pattern is worth noting. Owners say the stiffer sheet is easier to keep flat on the water than a large-bubble cover of the same weight, which matters if you have ever chased a floating sheet around the edge of a pool trying to line it up.
Temperature claims run from 14 to 27 degrees Fahrenheit depending on environment, which is a wide range because it covers everything from mild spring weather to strong summer sun. Owners who track their morning baseline readings report gains of 5 degrees or more, which is the number we would actually plan around.
The same 95 percent evaporation blocking claim appears here as across the category, and the range covers six sizes from 8×8 up to 40×20 feet, so this brand is a reasonable way to cover an inground pool on a budget regardless of shape.
Anchoring is the part you must plan for
This is a light sheet, and light sheets move. Buyers report it shifting and bunching if it is not weighted, so pair it with anchoring rope or water-filled bags rather than relying on friction alone. Some buyers also report that the floating anchoring bags arrive damaged, so inspect them before relying on them in a real gust.
Owners on r/swimmingpools describe a recurring pattern where a cover blows off the deck overnight despite weighting. The fixes that work in those threads are consistent: more anchor points, higher-tension rope, and never leaving a cover on when wind is forecast.
Durability is the tradeoff for the price
Several buyers report the material degrading within a season, leaving small plastic fragments in the water, so treat this as a one-to-two season cover rather than a long-term investment. That is still a defensible purchase for a smaller pool where the total cost of ownership matters more than longevity.
Two-person handling is needed on anything larger than this 12×24 sheet, and reviewers find the supplied carrying case largely unnecessary beyond transport. If you will be handling the cover alone, this lighter gauge is the more forgiving choice than a 16 mil.
8. Evoio 12 Mil Solar Bubble Cover 16×32 – Fastest Documented Heating
Evoio Solar Bubble Pool Covers for Above/Inground Pools 16 x 32 Ft
12 mil PE bubble film
384 inch L x 192 inch W
6-12 C daytime gain
Cuts to any shape
Pros
- Fast documented heating
- one 15000 gallon Texas pool went from 81 to 88 degrees in three sunny days
- Genuinely 12 mil with good tensile strength
- Cuts a ladder notch without further tearing
Cons
- Seams can separate after a season or two
- Some buyers say it is thinner than the advertised 12 mil
- Delivered length can run slightly under the stated size
The Evoio has the most concrete heating evidence of anything in this roundup. One owner documented a 15,000 gallon Texas pool moving from 81 to 88 degrees Fahrenheit in three sunny days, which is a real measurement on a real pool rather than a lab figure. The listed claim is 6 to 12 degrees Celsius during sunny days.
It is a 16 by 32 foot floating bubble cover in 12 mil polyethylene film, 384 by 192 inches. At 159 ratings it is early in its review history, so we would treat the durability verdict as provisional.
One genuine advantage is flexibility. The film cuts cleanly enough that owners can cut a notch for a pool ladder without the cut edge tearing, and the listing notes it suits rectangular pools, hot tubs and spas, which is why we badge it for small water features.
Evaporation reduction is the standard up to 95 percent, and the care instructions are unusually specific: clean it regularly, avoid leaving it in the sun out of the water when the pool is not in use, and keep it wet or submerged when stored on the pool.
Measure before you cut, every time
Buyers report that the delivered length can run slightly under the stated size, and others say the sheet feels thinner than the advertised 12 mil. Neither is a dealbreaker, but both mean you should measure the actual sheet against your pool before making any cut, because there is no un-cutting a cover that is cut short.
Seam separation after a season or two is the most common long-term complaint. In very intense sun the film can shrink and delaminate, so if you are in a high-UV region this is not the cover we would put on a roofless pool and forget about.
Why spa and hot tub owners like it
Small water features heat and cool faster than a full pool, so a cover that raises temperature quickly has a bigger visible effect there. A 16×32 sheet trims down easily to a spa or kiddie pool footprint without waste.
The tradeoff is the same as the rest of the 12 mil tier: light, easy to handle, and quicker to fail. For a spa that gets covered every night, that is a good trade. For a year-round inground pool, a heavier sheet is the better plan.
9. Doheny’s Clear-Tek Micro Bubble Cover 18×36 – Best Micro-Bubble Construction
Doheny’s Clear-Tek Micro Bubble Solar Pool Cover for In-Ground Swimming Pools | Increase Solar Energy Absorption, Retain Heat, Reduce Evaporation, Reduce Heat Loss & Save, 18×36 ft Blue 1600
Micro-bubble blue PE
432 inch L x 216 inch W
1600 Series
Made in the USA
Pros
- Micro-bubble film with twice the bubble count of standard covers
- Lighter and can increase solar absorption by 15 to 25 percent
- Made in the USA
- Scissors trimming does not void the warranty
Cons
- Weak heat-welded seams wrinkle
- lift and trap water
- Bubbles can arrive punctured or delaminate early
- Film tears more easily during fitting than standard bubble covers
The Doheny’s Clear-Tek is the only micro-bubble construction in this roundup, and it is also the only one made in the USA. The micro-bubble profile has roughly twice the bubble count of a standard solar cover, and the lighter, more transparent film is cited as increasing solar energy absorption by 15 to 25 percent over darker covers.
It is an 18 by 36 foot rectangle in blue polyethylene, 432 by 216 inches, from the 1600 standard series. It rates 3.9 stars across 589 reviews, which is the joint-lowest average here alongside the Sun2Solar.
Heating performance is not the problem. Owners report large, fast temperature gains, including one pool going from feet-only cold to comfortable within two days. Weights and handling are also praised, since the lighter film sits better on a solar reel than a conventional bubble sheet.
Cutting is worry-free in a way most competitors cannot match: trimming with scissors does not void the warranty. For a freeform or kidney pool that needs serious shaping, that guarantee is a genuine advantage over listings where cutting is buyer beware.
The listed benefit of cutting heating costs by up to 70 percent is in the same family as the 95 percent evaporation figures elsewhere in the category. It depends entirely on your climate, your heater runtime and how consistently the cover goes on.
Why the seams are the deciding factor
The complaint that shows up most often is the heat-welded seams. Owners describe permanent wrinkles that trap water and lift in wind, which is worse for wind resistance than a heavier flat sheet, because a wrinkle is an airfoil. This is the most credible reason to think twice about micro-bubble construction in a gusty location.
Defective bubbles are the second issue, with some buyers reporting punctured or delaminated bubbles on arrival and blue plastic dots shedding into the pool within weeks. The thinner 1600 series also does not lie as flat on the water as a heavier cover would.
What to check when your cover arrives
Inspect the bubbles before you cut anything, and reject a sheet that already has perforated or loose cells. The listing appears to mix the 1600, 2400 and 3200 series under one page, so check which series you actually received before comparing it to another cover.
With 16 percent one-star reviews, this is a higher-risk construction than the flat-film options. If you are in a high-wind region or need the cover to last more than a season or two, we would choose a 16 mil standard-bubble cover instead.
10. Sun2Solar 1200 Series 12 Mil 16×32 – The Most Proven Name in the Category
Sun2Solar Blue 16 ft x 32 ft Rectangle Solar Cover | 12 Mil
12 mil blue resin film
16 ft x 32 ft rectangle
512 square feet
1200 Series
Pros
- Largest review base in the roundup at 10786 ratings
- Works on both above-ground and inground pools
- Trims to fit around ladders and other protrusions
- Cuts chemical use and blocks leaves
Cons
- Thin 1200 series
- longevity commonly one to three seasons
- Reports of quality slipping across production runs
- Lowest-tier average rating at 3.9 stars
Sun2Solar is the name most pool owners recognise, and the 1200 Series 16 by 32 has 10,786 ratings behind it. No other cover in this roundup comes close to that volume, and when you want the longest available evidence base on how a cover ages, this is it.
It is a 12 mil blue resin film in a 16 by 32 foot rectangle covering 512 square feet, floating installation, listed as UV resistant and thermal insulating. The claimed result is up to 15 degrees of water temperature gain from solar energy, with up to 95 percent evaporation reduction.
The extra overlap design is the detail that separates it in practice. It makes installation and removal around ladders and other protrusions simple, and it is why this cover works on both above-ground and inground pools without modification.
Owners value the effect more than the build. Reported wins include conserving water, cutting chemical use, and blocking leaves and debris during autumn, and the sheet is light enough for daily handling on a 16×32 pool.
Heat retention after sunset is the second headline feature. The trapped air in the bubbles slows convective loss, which is the part of the equation you can actually measure in your own log book on the first cool night of autumn.
Treating this as a consumable, not an investment
The honest framing is a replace-every-few-seasons purchase. Owners commonly measure longevity in one to three seasons on the 1200 series, and material that degrades in strong sun leaves plastic fragments in the water, so budget for replacement rather than assuming a decade of service.
At 3.9 stars with 15 percent one-star ratings, it is tied for the lowest average here, and there is a recurring theme of quality slipping across successive production runs. The design has not changed much, but the consistency debate is real and worth factoring into your decision.
Why people keep buying it anyway
Because the price point and the heating effect are proven, and because most owners replace a cover every few years anyway. If you want a dependable, widely available cover for a 16×32 inground pool and you accept the replacement cycle, this does the job.
If you want the longest life out of a cover, step up to a 16 mil sheet such as the BigXwell or the VEVOR. The 1200 series is the right call for budget and familiarity, not for longevity.
How to Choose the Right Solar Pool Cover
Mil thickness: 8 mil vs 12 mil vs 16 mil
Thickness is the single most repeated question on this topic, and the short answer is that 12 mil is the sensible default for an inground pool while 16 mil is the better long-term buy if you can handle the weight. Eight mil is a light-duty gauge that belongs on an above-ground pool or a short warm-season use case, and it is the tier where tears and split seams show up first. Our buyer logic is simple: buy the thickest sheet you are willing to drag onto the water twice a week.
8 mil suits a small above-ground pool, a kiddie pool or a hot tub, where weight is the limiting factor. Expect the shortest service life of the three, because thin film deforms on waves and tears at seams before it degrades from UV.
12 mil is the standard choice for most inground pools. It is the tier behind the Blue Wave, the In The Swim, the VINGLI, the Goplus and the Evoio in this roundup, and it balances weight, price and durability. Handled alone, it is the most realistic gauge for daily use.
16 mil is the durability tier, represented here by the BigXwell, the Real Relax and the VEVOR. It sits heavier on the water, resists wind lift better, and is the gauge that tends to keep its bubbles intact longest. The cost is weight: expect to need a reel and, on a large pool, a second person.
Blue, clear and silver: which colour to buy
Blue is the standard for a reason. A darker blue film absorbs more solar radiation and is the default in every listing we reviewed, and owners generally see better overnight retention with it. Clear covers pass more light through, which some manufacturers claim increases absorption because the light reaches the water rather than heating the film, and our more detailed look at blue versus clear is in our heat-retention guide.
The trade-off is light transmission and algae. A cover that blocks light helps keep algae from starting, but any cover does that, and the difference is marginal compared with getting the cover on at all. Silver-backed covers reflect more and are the choice when maximum retention matters more than daytime gain, but none of the ten covers we reviewed is silver-backed.
Our take: buy blue unless you have a specific reason. It is the most documented construction in the reviews, and the durability data for blue PE is better established than for the lighter and clear variants.
How to size and cut a cover for an inground pool
Measure the pool across the longest length and the widest width, then add 6 to 12 inches of overlap on each side. You want the cover to sit over the coping rather than ending flush with the pool edge, because any exposed water at the perimeter is where evaporation and wind get in.
Do not cut to a tight fit on the first attempt. Every cover in this roundup shrinks slightly after first use, and trimming flush leaves a gap by the second month. Cut roughly 6 inches larger than you think you need, let the cover shrink on the water for a full season, then trim the slack.
For kidney, oval and freeform pools, buy a rectangle and cut it. Every cover here is listed as cuttable with ordinary scissors, and the Blue Wave and Doheny’s options are specifically praised for irregular shapes. Cut in short, smooth strokes and leave a smooth edge, because a ragged cut on PE film is where tears start.
Putting on, taking off and storing the cover
Wet covers are heavy. A dry 16×32 sheet at 16 mil is already a two-person unroll, and a wet one is worse. The practical routine is to float the cover, let it sit until the top surface is only damp, and then roll or fold it rather than dragging it across the deck.
A cover reel is the single most useful accessory and the one most owners skip. Without one, daily use means lifting a 30 to 44 pound sheet over the coping every morning, which is how a lot of covers end up on the garage floor unused. With a reel, deployment takes about a minute and the cover is off your list of chores.
For storage, rinse off debris, let it dry fully in the sun for a short while, then fold loosely rather than rolling it tight, which creases the bubbles. Store it somewhere cool and dry, out of direct sun, and away from anything that could puncture it in a garage.
Wind anchoring and blowout troubleshooting
No floating solar cover is windproof, and owners on r/swimmingpools describe a familiar pattern: a cover weighted down at the edges lifts in the middle, catches air, and ends up on the neighbour’s yard. The troubleshooting sequence we would use starts with more anchor points rather than heavier ones. A single rope per side creates a pocket that fills with air; four or six points pull the sheet flat.
Next, tension the rope. Slack line lets the cover billow, and tensioned line does not. Water-filled anchoring bags that sit on the perimeter are more effective than bags on top of the sheet, because they hold the edge down without creating a mound for wind to catch.
Finally, take the cover off when a strong gust is forecast. No anchoring system in this category survives a serious storm, and a cover that ends up in a tree is cheaper to replace than a cover that is gone. If your site is genuinely exposed, budget for a tensioned anchoring kit at installation rather than improvising with patio furniture.
Solar cover vs safety cover vs automatic cover
These three solve different problems and are not substitutes. A solar bubble cover is a floating thermal film that reduces evaporation and adds a little solar gain. A safety cover is a tensioned or anchored mesh or solid sheet designed to hold a person’s weight, and it is the only one of the three that keeps a child from drowning under it.
An automatic cover is a motorised mechanism with tracks, a housing and usually a safety release or alarm. It is the most expensive option and the one that does the most: automatic covers commonly combine a solar material with a safety rating, giving you heat retention plus a barrier.
Our practical recommendation for an inground pool in a shoulder-season climate is a solar cover for daily thermal use, plus a properly anchored safety cover or an automatic cover if young children or heavy leaf fall are factors. If you need a starting point on safety covers specifically, our broader pool cover guide covers the alternatives.
Frequently Asked Questions
Which brand of pool solar cover is considered the best?
For an inground pool, the BigXwell 16 mil 16×32 is the strongest all-round pick, combining 16 mil thickness with more than a thousand reviews and clean scissor cutting. The VEVOR 16 mil offers the same thickness at the value end, and the Real Relax 16 mil has the highest average rating in the group at 4.7 stars. If you want the most proven name rather than the best rating, the Sun2Solar 1200 Series has by far the largest review base in the category.
What is a good solar pool cover for an inground pool?
A 12 mil or 16 mil blue polyethylene bubble blanket sized slightly larger than your pool, with 6 to 12 inches of overlap on each side. At 12 mil, the Blue Wave and In The Swim covers are well documented. At 16 mil, the BigXwell is our overall pick because it sits heavy on the water, cuts cleanly and holds heat overnight. Add a cover reel and anchoring rope for daily use.
What thickness pool solar cover is best?
For most inground pools, 12 mil is the sensible default because it balances weight, price and durability and can be handled by one person for daily use. Sixteen mil is the better buy for longevity and wind resistance, but expect to need a reel and sometimes a second person to unroll it. Eight mil is light-duty and best reserved for above-ground pools, spas and short warm-season use.
Is blue or clear solar pool cover better?
Blue is the standard choice and the most documented in owner reviews, because the darker film absorbs more solar radiation and tends to hold heat overnight better. Clear covers transmit more light to the water, and some manufacturers claim a 15 to 25 percent increase in solar absorption over darker covers. In practice, blue wins on durability data and clear wins on light transmission, so pick blue unless you have a reason not to.
Can a solar pool cover support a child or a person’s weight?
No. A solar bubble cover is a thin floating film and cannot support any weight at all. A child can slip under it and drown without surfacing, which is why it looks far more load-bearing than it is. If you need a barrier that holds a person, buy a properly anchored safety cover or an automatic cover with a safety rating instead, and keep the solar cover off the pool whenever young children are around.
Our Verdict
The BigXwell 16 mil 16×32 is the best solar pool cover for inground pools in 2026 because it is the rare combination of thick film, high review volume and easy handling, and 4.5 stars across 1,035 ratings is a track record rather than a promise. The VEVOR 16 mil is the smarter money move if the same thickness matters more than the finish, and the Real Relax 16 mil is worth a look if the rating itself is your deciding factor.
Whatever you choose, buy one size up, cut it a season early, and pair it with a reel and real anchoring. And if you want actual heat rather than heat retention, a cover is the first step, not the whole plan, so read our solar pool heater guide next. Ten minutes of sizing work now beats a cover that sits short on the water all summer.
