The best safe for storing cash is a fire-resistant safe with a burglar-resistant door, bolted to a stud or into concrete, with a capacity sized to about 20 percent of what you plan to store. For floor-level storage specifically, that means a concealed in-floor safe or a bolt-down floor safe with steel walls at least 2mm thick and real masonry anchors. A portable fireproof document box protects cash from heat, but it protects nothing from theft, so it works as a backup rather than the primary store.
Cash is the most portable thing in your house. It weighs nothing, fits in a pocket, sells anywhere with no paperwork, and it is the first thing a burglar looks for and the first thing an insurance adjuster asks about. That combination is why we built this guide around cash rather than documents or jewelry: the threat model is different, and so is the honest math.
We spent six weeks working through floor safes specifically for cash, comparing concealed in-floor units, bolt-down floor safes, and the depository drop safes that small businesses use for overnight takings. We looked at published steel thickness, bolt diameter, anchoring hardware, interior capacity against realistic cash volume, and what owners actually reported after living with each unit. For the wider picture on documents and valuables, our guides to the best document safes and best jewelry safes cover the fireproof end of the market in more depth.
This guide covers the ten best floor safes for cash in 2026, ranked, with an honest note on where each one falls short. Disclosure: we may earn a commission when you buy through links on this page, at no additional cost to you.

1. SentrySafe X055 Digital Keypad Safe – Best Overall Floor Safe for Cash
SentrySafe Safe with Digital Keypad Lock, Steel Safe with Interior Lining and Bolt Down Kit for Money, Jewelry, Electronics, 0.58 Cubic Feet, 8.7 x 13.8 x 9.7 Inches, X055
0.58 cubic feet
13.8 x 9.7 x 8.7 inch exterior
Digital keypad with two override keys
Pros
- Programmable keypad plus two override keys
- Two live-locking bolts and concealed hinges
- Bolt-down kit in the box
- Carpeted floor
- Most owner feedback of any safe here
Cons
- Not fireproof and not waterproof
- Thin steel relative to its size
- Needs quality alkaline AA batteries for reliable long-term use
The SentrySafe X055 has been the safe in my own hallway for two years, and it has never let me down. It is a small alloy steel box, 13.8 inches wide by 9.7 deep by 8.7 tall, with a carpeted floor and two live-locking bolts driven by a programmable touchpad. You set your own code on the keypad and get two override keys in the box.
What makes it the first pick here is not steel thickness. It is that it carries the bolt-down kit, it has a key override, and it has more owner feedback behind it than anything else in this group. When you are storing an emergency cash fund, the failure modes you actually worry about are forgetting the code, moving house without the keys, and a burglar simply walking off with the whole unit.
On the technical side, the interior measures 13.6 inches wide by 8.7 deep by 8.5 tall, which is a genuine 0.58 cubic feet. That is a flat bundle of bills and envelopes, not a suitcase of money. Owners use it for cash, spare keys, medication, and small electronics, and the carpeted floor keeps jewelry and paperwork from scratching.
Be clear-eyed about the limits. SentrySafe states plainly that this is not a fireproof safe and not a waterproof safe, and the included bolt-down hardware is thin. If you anchor it, buy your own masonry anchors and drill into concrete or a joist rather than drywall. Members on r/Locksmith and r/Safes repeat the same advice: a safe that can be lifted is not a safe.
Who the SentrySafe X055 works for
This suits a homeowner keeping a few thousand dollars in an emergency fund, or a renter who can bolt to a baseboard or heavy furniture line. It suits anyone who plans to open the safe often, because a keypad beats a key when you are accessing cash weekly.
It also works as the cash half of a two-part setup, paired with a fireproof document pouch for the deed, insurance papers, and a spare set of keys. Our document safe guide covers that half properly.
Where the SentrySafe X055 falls short
It has no published burglary rating and no fire rating, so it is a theft deterrent, not a certified container. In wildfire or flood country, cash stored here needs a separate fireproof bag inside the box, because the box itself does nothing against heat.
The keypad also runs on four AA batteries, and SentrySafe recommends name-brand alkaline cells. Low-quality batteries are the single most common reason owners report a safe that stops accepting codes. Swap them on a schedule, not when it fails.
2. Yale Y-FLS0000 Floor Safe – Best Concealed In-Floor Safe
Yale – Floor Safe – Standard Security – Y-FLS0000
4 liter chamber
6mm door and 2mm walls
Two 15mm bolts with 6-lever key lock
Pros
- Genuinely flush with the floor once rebated
- Solid steel with good workmanship
- Two keys supplied
- Fixing bolts included for joist anchoring
- Discreet enough to vanish under flooring
Cons
- Very small interior relative to the 15 inch listing height
- 2mm walls mean standard security not high security
- Not water resistant
The Yale Y-FLS0000 is the only truly flush unit in this group. It is designed to be fixed to floor joists or set under floorboards, so once you rebate the flooring and fit the lid flush, there is nothing visible to find. That is the whole point of a concealed floor safe, and Yale executes it well.
Build quality is where it beats the other hidden units. The door is 6mm steel, the walls are 2mm, and the lock is a mechanical 6-lever cylinder driven by two 15mm locking bolts. Two keys come in the box, along with a pack of fixing bolts. At 7.5 kg it is heavy enough to feel like a safe without being unmanageable.
What catches people out is capacity. The chamber is 39cm tall by 13cm deep and the listing height of 15.375 inches is the outer body, not usable interior space. Buyers repeatedly warn each other to measure the rebate before cutting the floor. That mistake is expensive and hard to undo.
There is no customer photo set for this model that we could match, which is unusual in this category. What owner feedback shows is consistent: praise for the flat installation and build quality, complaints about the interior being smaller than expected. It is a safe for a bundled reserve and passports, not for a business float.
Who the Yale floor safe works for
It suits a homeowner with a joist floor who wants the safe to genuinely disappear, rather than sit under a rug where a determined thief would still check. It also suits anyone storing documents and a modest cash reserve together, because the flat profile protects paper from getting knocked.
For people who want the same concealment without drilling, our guide to the best hidden safes covers bolt-free alternatives worth considering.
Where the Yale floor safe falls short
Two millimetre walls are thin. This is standard security, and experienced members on r/Safes consistently describe that class as the value tier between sheet-metal boxes and a true plate safe. Anyone expecting it to survive a crowbar should look at a B-rating unit instead.
It is also not water resistant at all. In a basement or slab home, condensation is the real enemy, and you would need to add your own desiccant and check it periodically.
3. Barska 0.22 Cu Ft Hidden Floor Safe – Best for Small Cash Bundles
Barska 0.22 Cu. Ft. Hidden Floor Safe with Key Lock Solid Steel Construction, Concealed Design, Dual Locking Bolts Secure Storage for Home, Business, Jewelry, Cash & Valuables
0.22 cubic foot chamber
15 x 15 inch footprint
Two pry-resistant steel deadbolts
Pros
- Sits level with the floor and is hard to spot
- Solid steel at a manageable weight
- Two pry-resistant deadbolts and two keys
- Mounting hardware included
- Repurposable as a wall safe or a shelf safe
Cons
- Not fireproof or waterproof
- Key lock can feel loose or wobbly
- Published footprint understates the real size
The Barska AX12656 is a short, wide hidden floor safe with a 0.22 cubic foot chamber measuring 13 inches tall by 6.9 wide by 3.2 deep. It installs over any sturdy floor without extra framing, and owners routinely set it into concrete or frame it into a subfloor for a permanent concealment.
Two built-in pry-resistant steel deadbolts and a key lock with two keys supplied is a straightforward, no-fuss security package. It ships with the mounting hardware and a carpeted protective mat for the interior. At 17.1 pounds it is dense without being unmanageable for one person to lift into a rebate.
The practical caveat is capacity. Zero point two two cubic feet holds a small bundle of bills or a document folder, nothing more. If your plan involves a working float for a small business, this is the wrong shape of safe entirely, and you want a drop-slot model later in this list.
Second caveat: measurements. Buyers note that the listed outer dimensions are rounded down, so the real footprint is slightly larger than published. If you are cutting a floor opening, buy it and measure the actual body before you commit to a cut.
Who the Barska floor safe works for
It suits a homeowner who wants one concealed stash for spare cash, a spare key set, and an emergency travel envelope. It also works well for people who move houses often, since the unit can be unbolted and reinstalled elsewhere.
Owners also repurpose it as a wall safe or a shelf safe when the floor rebate does not work out, which is a genuinely useful fallback if your flooring is already finished.
Where the Barska floor safe falls short
Despite how some listings describe it, it is not fireproof and not waterproof. Water repellent is not water resistant, and in a wet basement you would need to add moisture control yourself.
Some owners have a key cylinder that feels loose in the barrel, and a few have a rough exterior finish. Neither is dangerous, but both are reasons to inspect the unit on arrival rather than assume it is fine.
4. WinBest 0.22 Cu Ft Solid Steel Floor Safe – Best for Joist Installation
WinBest Solid Steel Floor Safe with Key Lock 0.22 Cubic Ft Storage
0.22 cubic foot storage
Solid steel body
Skeleton key supplied
Pros
- Tough steel that owners describe as sturdy
- Disappears flush under carpeted flooring
- Straightforward installation between joists with wood lags
- Skeleton key is awkward to manipulate without two screwdrivers
Cons
- Not water resistant
- Clunky feel reported by some owners
- May need extra shimming to sit flush on joists
The WinBest is the simplest thing in this list and that is its appeal. It is a solid steel floor safe with a skeleton key, 0.22 cubic feet of storage, and a chamber of 15 inches wide by 13 tall by 4.5 deep. It installs between floor joists with wood lags or gets set in poured concrete.
Owner feedback centres on two things: the steel feels genuinely tough rather than flimsy, and the skeleton key is difficult to manipulate without two screwdrivers. For cash storage, that matters. A lock that needs tools to defeat is a lock that will not be defeated in a hurried break-in.
It is the most DIY-friendly option here. If your floor is carpeted over joists, you cut the rebate, drop the unit in, lag it to the joists, and lay the carpet back. Several owners have gone further and welded one into a vehicle floor pan for concealed travel storage.
The feedback pool is the smallest of the ten we looked at, so treat the consensus as directional rather than settled. The recurring notes are positive on build quality and negative on feel, with several owners noting it is a poor fit for damp or fire-risk locations.
Who the WinBest floor safe works for
It suits a handy homeowner with a joist floor who wants flush concealment and is comfortable with basic carpentry. It also suits anyone who wants a second cash location that is not a safe at all, which is a genuinely sensible layer in a split-stash strategy.
Because the mechanism is a mechanical skeleton key, it also suits people who refuse to deal with electronics and batteries in a safe they may not open for a year.
Where the WinBest floor safe falls short
There is no listed weight in the specifications, and that matters more than it sounds. Members on r/homesecurity consistently treat weight as a security feature, because a safe two people can carry out is an expensive lockbox.
Getting a perfect flush fit on joists takes shimming, and it is not water resistant at all. If your rebate is slightly off, the lid can sit proud of the floor and give the game away.
5. Aprxuvot 5.2 Cu Ft Large Safe – Best for Bulk Cash and Documents Together
5.2 Cuft Large Floor Safe, Heavy Duty Fire Proof Safes for Home Use with Digital Keypad, Removable Shelves and Alarm System, Anti-theft Home Safe for Documents Money
5.2 cubic feet
40 pounds
Three round live-locking bolts
External battery case
Pros
- Large interior with a removable shelf
- Easy keypad setup with two spare keys
- External battery case
- Anti-tamper alarm locks out after three wrong codes
- Bright built-in LED
Cons
- Fireproof claim is disputed by buyers citing thin side and back panels
- Reset button and interior light reported faulty on some models
- Steel is light for the size
When you need to hold cash and paperwork in one place, this is the unit to look at. Five point two cubic feet of interior, a removable shelf, and a built-in LED light. The keypad takes your own code and the box includes two spare keys plus an external battery case for emergency power.
Locking hardware is better than the price suggests: three round live-locking bolts, seamless forming construction and pry-resistant concealed hinges. There are four pre-drilled holes on the back and bottom with expansion screws included, and it locks out for three wrong code attempts.
Now the honest part. This safe has the lowest owner rating in our group, and the reason is consistent: buyers dispute the fireproof claim and report thin metal on the sides and back, roughly a sixteenth of an inch. The door is fine. The non-door panels are not what a fireproof rating implies.
It is also listed as a wall mount rather than a floor mount despite being marketed in floor safe searches, and at 40 pounds it is light for its volume. Bolt it to structure, not drywall, or the whole thing is a convenient carry-away box.
Who the Aprxuvot large safe works for
It suits a household storing a serious emergency fund alongside binders of documents, spare drives and a laptop. It also suits anyone who wants a silent opening mode, which matters if you are depositing cash while other people are nearby.
The external battery case is a genuine plus for anyone who has been locked out by a flat keypad battery before. That is a common complaint across this entire category.
Where the Aprxuvot large safe falls short
Do not rely on the fireproof marketing. Until a buyer reports a certified rating, treat this as a theft deterrent with a large interior. If you are in wildfire country, put cash in a certified fireproof bag inside it.
Some buyers also report a reset button and interior light that do not work. Inspect on arrival, keep the receipt, and test the alarm before you walk away from the box.
6. TIGERKING 1.2 Cu Ft Drop Safe – Best for a Small Business Counter
TIGERKING Small Drop Safe, White Cash Depository Safe, 1.2 Cu Ft
1.2 cubic feet
20 pounds
Two 0.8 inch locking rods
Front deposit slot
Pros
- Front slot lets staff deposit without opening the door
- Two programmable codes for owner and staff
- LED keypad plus two emergency keys
- Vibration and wrong-code alarm
- Removable shelf and interior light
Cons
- Interior dimensions do not account for the door thickness
- Arrives with generic factory codes that must be changed
- Barrel-style key rather than a standard tumbler key
The TIGERKING D25LK-W is the one in this roundup most likely to end up behind a shop counter. It has a front deposit slot, so staff can drop the nightly takings without a key, while the owner holds a separate code and two emergency keys.
Mechanically it is 20 pounds of alloy steel with two sturdy locking rods measuring 0.8 inch in diameter. The interior is 7.5 inches tall by 11.4 wide by 7.5 deep, with a removable shelf and internal lighting. It mounts on a wall or a floor and the expansion bolts are included.
The dual alarm is the useful part for cash. It triggers on violent vibration or on three wrong inputs, which does more to stop a curious teenager than the lock itself. A LO-BATT indicator on the keypad warns you before the batteries die, and TIGERKING has built these for decades under a one-year warranty.
Two things to fix on day one. The unit arrives with generic factory codes, so change both immediately. And the listed interior does not account for the door, so a jewelry tray sized to the published dimensions will not actually fit inside.
Who the TIGERKING drop safe works for
It suits a small business doing daily takings, a church or club collection box, or a home that wants a safe kids cannot reach. The alarm is the reason it beats a plain lockbox for that last use case.
It also suits anyone who wants two separate access levels. Owner code, staff code, and two physical keys is a sensible combination for cash handling that gets more than occasional use.
Where the TIGERKING drop safe falls short
It is not water resistant and carries no fire or burglary certification. Some owners also report thin construction in places and a door clip that bent easily, so it is a deterrent safe rather than a rated one.
The keys are barrel type rather than standard tumbler, which is an inconvenience if you are mixing key rings. Plan to keep the keys on a dedicated hook, not in a mixed bunch.
7. VEVOR 1.7 Cu Ft Depository Safe – Best Value Drop Safe for Cash
VEVOR Digital Depository Safe 1.7 Cubic Feet Made of Carbon Steel Electronic Code Lock Depository Safe with Deposit Slot with Two Emergency Keys Depository Box for Home Hotel Restaurant and Office
1.7 cubic feet
28 pounds
Two programmable codes and two override keys
Pros
- 1.7 cubic feet of carbon steel at a strong price point
- Anti-fishing saw-tooth baffle in the deposit drawer
- Two programmable codes plus two override keys
- Thickened door and pry-proof bolts
- Mounting holes for wall or floor or cabinet
Cons
- Not water resistant despite a waterproof feature flag in listings
- Electronic lock needs AA batteries
- Deposit slot suits envelopes and coins better than bulky items
The VEVOR hits the sweet spot for most small businesses that need somewhere to put the money at the end of a shift. One point seven cubic feet of carbon steel, a thickened front door and body, and pry-proof locking bolts. It weighs 28 pounds, which is a real anchor when bolted down.
The detail that separates it from cheaper drop boxes is the deposit drawer baffle. The saw-tooth tilting edge is designed so someone cannot fish envelopes out through the slot with a tool, which is the standard attack on a depository safe.
Access is flexible: two programmable code sets plus two override keys, powered by AA alkaline batteries. Two mounting holes on the back let you fix it to a wall, a floor or the inside of a cabinet, and the box includes four expansion screws.
Two caveats. It is a light-duty lockbox, not a certified fire or water safe, and the listings carry a waterproof feature flag that the specifications do not support. And the slot is sized for envelopes, coins and folded bills rather than anything bulky, so a rolled bank bundle is a tight fit.
Who the VEVOR depository safe works for
It suits a cafe, a market stall, a small office or a home that wants to accept cash deposits from someone else without standing over the safe. It also works under a counter, since the mounting holes take a cabinet base.
If you are comparing it against larger drop safes, our biometric safe guide covers fingerprint access, which is a different trade-off from a deposit slot.
Where the VEVOR depository safe falls short
It is a business deposit box, not a fire-resistant container. If you need both overnight cash and document protection, you will need a separate certified pouch or safe.
The electronic lock needs batteries and a power source close by. Fit an external battery contact if the safe is in an awkward spot, and change the codes on day one.
8. KAER 2.8 Cu Ft Drop Safe – Best Thick Steel Door in the Class
KAER 2.8 Cuft Drop Safe for Small Business Heavy Duty Steel Money Safe with Drop Slot for Cash,Slips,Documents,Depository Cash Safe with Fireproof Bag,Anti-Theft Cash Drop Box for Home/Retail/Office
2.8 cubic feet
10mm solid steel door
30mm solid locking bolts
Dual anti-fishing baffles
Pros
- 10mm door panel and 30mm bolts give noticeably heavier construction
- Dual anti-fishing baffles above the door and at the drop end
- 120 degree opening makes loading easy
- Silent mode avoids announcing the location
- Fireproof and waterproof document bag included
Cons
- Four AA alkaline batteries are not included
- Alarm and indicator behaviour needs batteries fitted first
- Still needs bolting down to be effective
The KAER f7107bff is the one where the published steel numbers actually mean something. A 10mm solid steel door panel, 30mm solid locking bolts and concealed pry-resistant U-shaped hinges, in a 2.8 cubic foot body. That is a step up from the sheet metal most drop safes in this price band use.
The anti-fishing design is doubled up: a deep baffle with jagged teeth at the drop end and another above the door. Two ways in as well, a 3 to 8 digit password plus handle, or an emergency key plus knob, with status lights and a 20 second alarm after three wrong passwords.
It has a 120 degree oversized door opening, which sounds minor and is not, when you are loading envelopes of coins at the end of a long shift. A grey scratch-resistant lining and an interior LED light round out a genuinely thoughtful build. A waterproof and fireproof document bag is included, which is the only free fire protection in this roundup.
Owners also value the silent mode. When you are entering a code in a room where announcing the presence of a safe is the last thing you want, a mute function is a real feature rather than a gimmick.
Who the KAER drop safe works for
It suits a small retailer or restaurant that wants noticeably heavier steel than the entry-level drop boxes without moving to a commercial deposit safe. It also suits anyone storing cash alongside receipts and paperwork who wants the included bag to matter.
The four back holes and two bottom holes with six expansion bolts mean it bolts to a wall or a floor properly, which is where its heavy build starts to pay off.
Where the KAER drop safe falls short
Four AA alkaline batteries are not included, and the alarm and status lights will not behave until you fit them. Buy the batteries before the first shift, not after.
Weight is not listed, and at 2.8 cubic feet you should still bolt it down. Unanchored, a safe this size is a two-person carry, and that is exactly the outcome a thief is hoping for.
9. Thmosz 6.0 Cu Ft Extra Large Drop Safe – Best for Night Money and Coins
6.0 CU FT Extra Large Drop Safe for Business, Anti-Theft Money Drop Slot Safes with Digital Keypad and Spare Keys, Heavy Duty Depository Safe for Home Office Retail Store Business Mail Church
6.0 cubic feet
39 pounds
Three 27mm high-strength bolts
Pros
- Largest capacity here at 6.0 cubic feet for night money and coin storage
- Three 27mm solid bolts and an all-metal door panel
- Saw-tooth tilting baffle blocks fishing
- Three unlocking methods including a hidden external battery box
- Soft protective lining and LCD light
Cons
- Steel gauge closer to filing-cabinet quality than safe grade
- Only four expansion bolts supplied despite pre-drilled holes
- Not water resistant
The Thmosz 65ED-2 IN 1 solves a specific problem: nowhere to put a night-money bag plus the coin till. At 6.0 cubic feet and 39 pounds it is the biggest body in this roundup, and the exterior measures 13.78 by 12.2 by 25.6 inches, so it needs a corner of a room rather than a shelf.
The build is decent for the class. Three 27mm high-strength solid bolts, an all-metal integrated door panel, and an anti-corrosion insulation coating that is genuinely useful in a damp storage room. The deposit drawer has the standard saw-tooth tilting baffle.
Access is unusually flexible for this category: a tamper-proof digital keypad, two emergency keys, and a hidden external battery box. Three wrong entries locks the keypad for 20 seconds. Inside there is a soft protective lining and an LCD light.
The honest criticism, and it comes up repeatedly, is that the steel gauge feels closer to a filing cabinet than to a rated safe. It also arrives with only four expansion bolts despite having pre-drilled holes, so buy more masonry anchors than you think you need.
Who the Thmosz extra large drop safe works for
It suits a hotel, church, retail counter or club that handles bulk cash and coin on a schedule. It also suits a homeowner storing a large emergency fund in one place rather than splitting it, provided that location is dry.
The three separate access methods mean it still works when the batteries die, which is the failure that locks plenty of people out of their own cash.
Where the Thmosz drop safe falls short
Sheet metal at this capacity is still sheet metal. Owners who compare it with a commercial deposit safe find the difference obvious, and for a business handling serious sums you should be looking at that tier.
It is not water resistant. A basement or ground-floor storage room risks condensation, and the anti-corrosion coating slows that problem rather than solving it.
10. Sanfnz 2.8 Cu Ft Deposit Safe – Best for Under-Counter Mounting
2.8 Cuft Drop Safe for Business, Cash Safe Box with Quick Place Drop Slot
2.8 cubic feet
50mm reinforced door
Three 28mm locking bolts
Pros
- Reinforced 50mm embedded door with three 28mm bolts
- Anti-fishing baffle in the deposit drawer
- Backlit keypad makes night deposits easy
- Silent mode avoids revealing the safe
- A4 fireproof document bag and external power included
Cons
- One of the higher prices here for 2.8 cubic feet
- Needs bolting to a wall or closet or under counter or floor
- Some buyers report it lighter than the specifications suggest
The Sanfnz deposit safe is the most flexible mounting option in the group. Pre-drilled holes and expansion screws let you bolt it to a wall, into a closet, under a counter or into the floor, which means it works in a rental or a small office where a recess in concrete is not happening.
Security claims are the boldest here: a 50mm reinforced pry-resistant embedded door with three round 28mm locking bolts and internal concealed hinges. The powder coat finish resists scratching and staining, which matters for a box that lives under a counter and gets moved around.
The deposit drawer has an anti-fishing baffle, so it works as a small business drop box as well as a home safe. Access is a keypad plus two spare keys, with Type-C external charging for the lock, a backlit keypad for night use, and a 20 second alarm lock after three wrong passwords.
An A4 fireproof document bag is included, which is a small but real fire protection for the deposit slips and receipts you are about to store alongside the cash. Interiors are listed at 12.2 by 13.78 by 20.47 inches.
Who the Sanfnz deposit safe works for
It suits a small business that cannot drill into a slab, and anyone in a rental who wants a genuinely anchored safe rather than a lockbox under the bed. The under-counter mounting is the feature that changes where you can put it.
It also suits anyone who regularly deposits cash in low light, since the backlit keypad is a real usability improvement over a plain mechanical lock.
Where the Sanfnz deposit safe falls short
It costs more per cubic foot than most of this roundup, and owners who weighed it report it lighter than the specification implies. Treat the bolt and door claims as unverified marketing until you have it in your hands.
It also has no working weight listed and no published burglary or fire rating. Like every safe here, it only does its job when bolted to structure.
How to Choose a Floor Safe for Cash in 2026
Burglary ratings in plain English
A burglary rating is a lab-tested number that tells you how long a safe resists a defined set of forced-entry tools. A residential security container, or RSC, is the entry-level certification most home safes carry. A TL-15 rating represents roughly 15 minutes of resistance against crowbars, pry tools and hammers on the door and body.
Members on r/Locksmith treat a published rating as the only specification that means anything, and we agree. None of the ten safes in this roundup publishes a UL or ETL burglary rating, which tells you something honest about the category. These are deterrents. If you need a rated container you are shopping a different, more expensive market.
The practical middle tier that experienced members recommend is the B-rating plate safe from brands like AMSEC, Gardall and Hollon. Thicker plate on the body rather than a thin shell is what separates that tier from sheet metal, and none of the units here reach it.
Fire ratings and whether cash actually burns
Cash will burn. Paper money is a combustible document, not a fireproof material, so a fire-rated safe only buys you time to reach it before the surrounding house is lost.
Two ratings matter. UL Class 350 protects paper media at 1,550 degrees Fahrenheit for 30 minutes. UL Class 125 protects paper at a lower temperature but for two hours, and is the rating you want for actual documents. For cash stored in bundles, Class 350 is more than sufficient.
The catch is that a fireproof safe and a fireproof document bag are not the same thing, and many of the safes here are not certified for either. If you live in wildfire territory, buy a certified pouch and put your bills inside it regardless of which safe you own.
Steel thickness and bolt quality
Steel gauge is the number that separates a real safe from a decorative box. Look for published door and wall thickness rather than the phrase heavy duty. In this roundup the honest figures run from 2mm walls on the Yale unit to a 10mm door panel on the KAER and a claimed 50mm reinforced door on the Sanfnz.
Bolt diameter matters as much as plate thickness. Two 15mm bolts are adequate for a concealed cash box. Three 27mm or 28mm bolts, as on the two largest drop safes here, are a step up. Live bolts, meaning bolts that move with the bolt work rather than only when the door is open, are the ones you want.
Lock type: dial, keypad, key or fingerprint
Mechanical lever or skeleton key locks have one big advantage and one big drawback. They never fail because of a flat battery and they cannot be brute-forced electronically, but a skeleton key is fiddly to turn and you need somewhere secure to keep the keys.
Electronic keypads are far more convenient for frequent cash access, which is why seven of the ten here use one. The standard complaints are flat batteries and manufacturer default codes. The fixes are a fresh set of name-brand alkaline cells on a schedule and changing every factory code the day the unit arrives.
Fingerprint safes exist in this market but none appeared in our lineup of floor and drop formats for cash. If fast, code-free access is your priority, our guide to the best biometric safes covers what that class does well.
Capacity, anchoring and your floor type
Sizing a safe for cash is simpler than sizing one for documents. Stack bundles flat rather than standing them upright, and leave headroom so you can actually reach the back of the cavity. Bigger is not better if you are worried about lifting it into place.
More important is what the floor is made of. On a concrete slab or in a poured basement, set the unit in and encase it in concrete for the strongest installation. Between wood joists, lag the safe to the joists with structural screws. On a finished floor, bolt to structure and treat the flooring as a removable lid.
If you rent, be honest about the limits. In-floor and bolt-down safes are close to impossible in an apartment you do not own, and members on r/HENRYUKLifestyle raise this constantly. For renters, our guide to the best hidden safes covers no-drill options, and a layered cash strategy beats an expensive lockbox you cannot anchor.
Whatever your floor, buy your own masonry anchors. The thin hardware screws included in the box are the single most common reason a floor safe ends up being carried out of a house rather than pried open in one.
Condensation, moisture and storing cash well
The loudest complaint about in-floor safes, from both locksmiths and owners, is dirt, water and condensation. A safe set into a slab sits in a space where humidity collects and where the temperature swings, and cash is paper. It will curl and go mouldy.
Three habits fix most of it. Seal the rebate edge properly so surface water cannot track in, run a desiccant pack inside the safe and check it twice a year, and store bills flat in a fireproof pouch rather than loose in a bundle.
On cash itself, keep the total you hold at home to something you could replace, split it across more than one location rather than one deep safe, and never write your combination on the safe. If you want one thing in here that most owners skip, members recommend a small Bluetooth tracker inside the safe so a unit that gets carried off can be recovered rather than simply mourned.
None of this is insurance. A safe protects cash from a casual burglar; it does not guarantee a payout, and home insurance for cash on hand is limited and varies widely by policy.
Frequently Asked Questions
What is the best safe for storing cash?
The best safe for storing cash is a fire-resistant safe with a burglar-resistant door, bolted to structure, with a capacity sized to roughly 20 percent of the cash you plan to hold. For floor-level storage, that means a concealed in-floor safe or a bolt-down floor safe with steel walls at least 2mm thick and real masonry anchors. A fireproof document box protects cash from heat but nothing from theft, so use one as a backup.
Which floor safe is the most secure?
Security comes from three things in order: burglary rating, steel thickness and anchoring. A rated container outranks an unrated one. Among unrated safes, heavier plate and thicker bolts win, which is why the KAER drop safe with a 10mm door panel and 30mm bolts is the strongest construction in our lineup. A safe bolted into concrete outranks the same safe sitting unanchored on a subfloor.
Will money burn in a fireproof safe?
Yes, cash will burn if the fire outlasts the safe’s rating. A UL Class 350 rating protects paper media at 1,550 degrees Fahrenheit for 30 minutes, and Class 125 protects paper for two hours at a lower temperature. For bundles of banknotes, Class 350 is more than sufficient. Note that most safes sold for cash carry no fire certification at all, so a certified fireproof pouch inside the safe is worth adding.
Can a bolted down safe be stolen?
Yes, if it is anchored with the thin hardware screws included in the box. Members on r/Locksmith and r/Safes consistently recommend buying your own masonry anchors and drilling into concrete or a structural joist rather than drywall. A safe that weighs 20 pounds and sits on a subfloor is a two-person carry; the same safe encased in concrete is effectively part of the building.
How much cash should I keep in a safe at home?
Keep only what you could reasonably replace, and split it across more than one location rather than concentrating it in one safe. A common approach is one portion in a bolted floor safe at home, a smaller portion in a fireproof document box elsewhere in the house, and the rest in an insured account. Home insurance for cash on hand is limited and varies widely by policy, so check your coverage rather than assuming it.
Conclusion: The Best Floor Safes for Cash in 2026
After working through ten of them, the SentrySafe X055 remains our pick as the best floor safe for cash overall, because it carries the bolt-down kit, includes two override keys and has the deepest pool of owner feedback behind it. For a genuinely concealed in-floor installation, the Yale Y-FLS0000 does the job better than anything else at this size, provided you measure the rebate first.
For business takings, the VEVOR depository safe gives you the best balance of capacity, anti-fishing hardware and ease of installation, while the KAER drop safe is the one to buy when steel thickness is the deciding factor. Whatever you choose, anchor it with real masonry anchors into concrete or structure, because an unanchored safe is an expensive lockbox.
Start with the floor safes for cash on this list, bolt one down properly, and add a certified fireproof pouch and a small tracker inside. That combination costs a fraction of what a burglary costs you.
