9 Best Large Fireproof Waterproof Safes (November 2026)
The best large fireproof waterproof safes include the Mitlvge 23.62'' Tall Extra Large Home Safe (best overall), the FOWORE 23.6" Tall Large Home Safe for shared homes, and the Homirxan 3.4 Cuft Large Fireproof Safe Box for small-floorprint rooms.

- What does a fire rating on a safe actually cover?
- How much water protection do you get?

- Where should you place a large fireproof waterproof safe?
- The verdict: which large fireproof waterproof safe should you buy?
The best large fireproof waterproof safe for most homes is the Mitlvge 23.62'' Tall Extra Large Home Safe. Its 5 cu ft interior takes document folders and cash behind a 50mm door with three 20mm locking bolts, and the included bag adds fire protection for papers.
Measure your laptop against its 11.4 in chamber depth before you count on it fitting.
If you need a cabinet with its own fire and water rating, the RXUJYC biometric safe and the SentrySafe models are the ones to compare.
Large safes split into two families, and the split matters more than brand. Steel cabinet safes give you space, shelves and a keypad, but most carry no cabinet fire rating and only ship with a fireproof bag.
Rated document safes carry real fire and water tests, yet their interiors are smaller and built around paper.
This guide sorts the nine picks by what each one actually protects. Every score weighs specs, features and how well each safe fits what a buyer looking for a large fireproof waterproof safe needs.

The best large fireproof waterproof safes, ranked
The top picks are steel cabinet safes with the most usable space and the best layout control. The rated cabinets lower down are the safer choice when tested fire and flood protection matters more than volume.
Mitlvge 23.62'' Tall Extra Large Home Safe: Best overall
- 5 cu ft capacity
- 50mm steel door with three 20mm locking bolts
- Three removable steel shelves
- Fireproof document bag rated 30 min at 1700 F
- Programmable keypad with backup key
A tall 5 cu ft cabinet with three shelves, a thick pry-resistant door and a fireproof bag for papers. It gives most households the most usable room for the money.
Pros
- Largest usable interior among the steel cabinet safes here
- Three removable shelves adapt to laptop and document loads
- Sensor light and silent alarm mode
Cons
- The bag carries the fire rating, not the cabinet
- 38.8 lb empty weight needs two people for stairs
The Mitlvge is the easiest safe here to live with day to day. A 23.62 in tall cabinet gives you 5 cu ft split across three removable steel shelves, so document folders, cash and jewelry each get a tier.
The door is 50mm thick with three 20mm locking bolts and concealed hinges. That is serious steel for this price tier, and the safe bolts to a wall or floor with the included expansion bolts if you want to stop a quick carry-out.
Fire and water protection come from the included bag rather than the cabinet. The bag is rated for 30 minutes at 1700 F and measures 9.36 x 13.26 inches, so it takes A4 letters and cash but not a laptop.
Treat the cabinet as theft protection and the bag as the paper backup.
The keypad takes a code, locks out for 20 seconds after three wrong tries and five minutes after six. A sensor light turns on when you open the door.
At 38.8 lb empty, plan a spot before it gets heavy.
FOWORE 23.6" Tall Large Home Safe: Best for shared homes
- 4.6 cu ft capacity
- 50mm door with three 20mm locking bolts
- Three removable shelves
- External battery box and two override keys
- Beeping and silent alarm modes
A near-twin of the top pick with more ways back in when a code is forgotten or batteries die. The silent mode suits bedrooms and apartments.
Pros
- Three ways to open: keypad, override keys and external battery box
- Silent mode for quiet rooms
- Three shelves customize the layout
Cons
- Cabinet is not rated fireproof; only the included bag is
- Slightly less capacity than the Mitlvge
The FOWORE is the same size class as the top pick and solves the one problem keypad safes create: getting locked out. You can open it with the keypad, with two override keys, or with an external battery box when the batteries inside die.
Its 4.6 cu ft cabinet is split by three removable shelves, and the interior takes an A4 file and a 16-inch MacBook Pro. That makes it a practical office safe as well as a home one.
The alarm gives a short alert tone after three wrong PINs, and silent mode turns the sound off for bedrooms and apartments. The trade-off is the same as the Mitlvge: the cabinet has no fire rating, and the fireproof and waterproof bag is the only protection for paper.
Choose it over the top pick if a shared home means codes get forgotten or batteries run down. The override keys are the difference between a nuisance and a locksmith bill.
Homirxan 3.4 Cuft Large Fireproof Safe Box: Best for small-floorprint rooms
- 3.4 cu ft capacity
- Three live locking bolts
- Removable shelf
- Built-in LED light
- Dual alarm with silent mode
The shortest cabinet here, so it fits under a desk or in a closet where taller safes cannot go. It trades height and shelves for an easier spot in tight rooms.
Pros
- Low 17.72 in height fits closets and under desks
- External battery case for dead batteries
- Carpeted floor mat protects jewelry
Cons
- Only one shelf, so tall and small items compete
- Smaller interior than the top two picks
The Homirxan wins on floor space. At 17.72 in tall it fits under a desk or on a closet shelf, places where the 23 in cabinets here will not go.
The 3.4 cu ft interior still takes documents, drives, cards and medicine.
It uses three live locking bolts and a recessed door with concealed hinges, and the carpeted floor mat keeps jewelry and electronics from scratching. A removable shelf lets you clear the full height for one tall item.
The dual alarm locks the safe for 20 seconds after three wrong codes and sounds an alert. Silent mode keeps it quiet at night.
An external battery case covers a dead battery.
The trade-off is height and shelves. One shelf means tall items and small items compete for the same space, and the wall-only mounting limits where you can put it.
Pick it when the room is the constraint, not the load.
SentrySafe HD4100 File Box: Best for paper files only
- 0.65 cu ft capacity
- UL Classified 30-minute fire protection
- ETL Verified water protection
- Fits hanging file folders
- Key lock with two keys
A chest-style box built around hanging folders. It is one of several rated cabinets here, with both a fire rating and a water rating on the cabinet, but it holds paper, not laptops.
Pros
- UL Classified fire protection for 30 minutes
- ETL Verified water protection
- Interior takes hanging file folders upright
Cons
- Smallest capacity in this group
- Key lock only, with no keypad
The SentrySafe HD4100 is a file box, not a cabinet, and it is the pick for paper only. It is UL Classified to 30 minutes of fire protection and ETL Verified for water exposure, so the box itself is tested, not just a bag inside it.
The interior fits hanging file folders upright, which makes passports, birth certificates, insurance records and legal paperwork easy to flip through. Built-in straps hold smaller items flat.
A key lock with two keys keeps the lid shut and the contents private.
Capacity is 0.65 cu ft, the smallest here. It will not take a laptop or a stack of drives.
For a home office that needs tested paper protection and nothing else, it is the most honest safe in this roundup.
The key-only lock means no code to forget, but also no quick access in the dark. Keep a key within reach but away from the box.
SentrySafe SFW123DSB: Best for tested flood protection
- 1.23 cu ft capacity
- UL Classified 1 hour at 1700 F
- ETL Verified 24 hours in 8 in of water
- Four live locking bolts
- Dial combination lock
The strongest water claim in this roundup, at 24 hours in 8 in of water. The dial lock and 86 lb body make it a serious cabinet for documents in a flood zone.
Pros
- 24 hours of ETL Verified water protection
- One-hour UL fire rating at 1700 F
- Four live locking bolts and pry-resistant hinge bar
Cons
- 86 lb, so plan where it lands before moving it
- Dial lock is slower to open than a keypad
The SentrySafe SFW123DSB is the safe to pick when flood risk is real. It is ETL Verified for 24 hours in water up to 8 in deep, and UL Classified to one hour at 1700 F.
That combination is rare at this size.
The 1.23 cu ft interior is small next to the steel cabinets, so think documents and valuables rather than laptops and folders. Four live locking bolts and a pry-resistant hinge bar make the cabinet hard to force.
It also carries two claims the others do not match. It is ETL verified to survive a 15-foot fall during a fire and stay closed, and SentrySafe will replace the safe if fire or water damages it.
An 86 lb body means you place it once and leave it.
The dial lock is slower than a keypad and not ideal for quick access. For a basement or a home near a river, that trade is easy to accept.

FOWORE 27.56"H Steel Safe Box: Best for tall storage
- 6 cu ft capacity
- 27.56 in tall cabinet
- Three removable shelves
- 50mm door with three 20mm bolts
- Fireproof and waterproof document bag
The tallest safe here and the biggest stated capacity. The narrow 13.78 in width squeezes into a closet corner while giving you six cubic feet stacked upward.
Pros
- Tallest cabinet in the roundup at 27.56 in
- Three shelves split the height into usable tiers
- External battery pack for dead batteries
Cons
- Stated 6 cu ft capacity looks optimistic for the exterior size
- Cabinet is not rated fireproof; only the bag is
The FOWORE 27.56"H is the tallest safe here, and its narrow footprint is the point. At 13.78 in wide it slips into a closet corner, and its 27.56 in height stacks storage upward where floor space is short.
The maker states 6 cu ft, which is the largest FOWORE capacity in this roundup. Compare that with the exterior size before you plan a load, because the cabinet is only 11.81 in deep.
A 12 in chamber depth suggests it holds less than the figure implies. Three removable shelves help you split the height into tiers.
The door is 50mm with three 20mm bolts, and the keypad pairs with two spare keys and an external battery pack. A fireproof and waterproof bag comes in the box for paper and cash.
Pick it for a narrow closet or a corner where width is the problem. Do not pick it expecting the full six cubic feet.
FOWORE 4.4 Cuft Safe Box: Best for wide items
- 4.4 cu ft capacity
- 23 in height
- Removable shelf
- Fireproof and waterproof A4 bag
- Three ways to open
A mid-height cabinet with a sloped keypad that is easier to read than flat panels. The included A4 bag takes documents and cash before they go inside.
Pros
- Sloped keypad is easier to see and reach
- External battery box and two spare keys
- Low-battery warning lights on the keypad
Cons
- Single shelf offers less layout control
- Cabinet is not rated fireproof; only the bag is
The FOWORE 4.4 Cuft is the safe for someone who opens it several times a day. Its sloped keypad sits at an angle, which is easier to read and reach than the flat panels on most cabinets here.
At 23 in tall and 14 in wide, it sits between the top picks and the small Homirxan. One removable shelf and a felt pad give you a base layer for larger items and a top layer for jewelry or electronics.
The A4 fireproof bag holds documents and cash.
Three ways to open cover the usual failures: keypad, two spare keys and an external battery box. A low-battery warning lights both indicator lamps, so you get notice before a lockout.
The safe bolts to a wall.
The single shelf is the limit. If you want to separate a laptop from document folders from jewelry, the three-shelf cabinets suit you better.
RXUJYC 9.2Cub Large Fireproof Waterproof Biometric Safe: Best fire and water rating on the cabinet
- 35 minutes of fire protection at 1700 F
- Cabinet described as fireproof and waterproof
- Fingerprint, code and key entry
- 76 lb body
- Hidden bottom compartment
The only cabinet here that claims its own fire rating plus water protection, and it adds fingerprint entry. The 9.2 cu ft figure and the no-drill design need a close look first.
Pros
- Cabinet itself carries a 35-minute fire claim
- Fingerprint access for quick opening
- 76 lb body resists carrying away
Cons
- No mounting holes, so it cannot be bolted down
- 9.2 cu ft stated capacity is far larger than the exterior size suggests
The RXUJYC is the only steel cabinet here whose cabinet itself carries a fire rating, at 35 minutes and 1700 F, alongside a waterproof description. It also opens by fingerprint, code or key.
The body weighs 76 lb, which resists carrying it off, and it has a hidden bottom compartment beneath the removable shelf for valuables you want out of casual view. Two removable partitions let you reshape the storage.
Two details need a close look before you buy. The stated 9.2 cu ft does not match the 15 x 16.9 x 31.5 in exterior, so expect less usable space than the figure suggests.
It also has no mounting holes, so it cannot be bolted to a wall or floor.
Pick it for a rental or apartment where drilling is not allowed and you want rated protection in the cabinet. Skip it if you need the safe anchored against a determined thief.
Amazon Basics 2.13 Cu Ft Fire and Water Safe: Best for tested fire and water on a budget
- 2.13 cu ft capacity
- Intertek tested 60 minutes at 1700 F
- Intertek tested 24 hours in 8 in of water
- Six live locking bolts
- Removable shelf and drawer
The cabinet itself is tested for an hour of fire and a day of water. It is the strongest rated safe here, though its wide body and modest interior limit what fits.
Pros
- 60-minute fire test at 1700 F by Intertek
- 24 hours of water protection tested by Intertek
- Six live locking bolts and bolt-down hardware
Cons
- 2.13 cu ft is small for the 20.87 in width
- 61.86 kg body is heavy to move once filled
The Amazon Basics safe has the best tested protection in this roundup: Intertek tested it for 60 minutes at 1700 F and for 24 hours in water up to 8 in deep. Both ratings sit on the cabinet.
Six live locking bolts and pry-resistant dead bolts secure a heavy-duty steel body, and bolt-down hardware comes in the box. Inside, a removable shelf and drawer help separate small items from larger ones.
The problem is the shape. The cabinet is 20.87 in wide, but the capacity is only 2.13 cu ft.
That width buys a heavy door and thick walls rather than storage room, so a 14-inch laptop and document folders get tight.
Pick it when tested fire and flood protection matter more than volume. For a document archive in a flood zone on a budget, this is the strongest rated pick here.

How these large fireproof waterproof safes compare
The table lines up capacity, fire and water protection and locking for each pick. Read the fire column carefully: most cabinets here protect paper through a bag, not through the cabinet itself.

Our score weighs specs, features and how well each safe fits a buyer who needs large storage plus fire and water protection. The three cabinet safes at the top earn their scores on space and layout, while the rated cabinets score lower on volume but higher on tested protection.
What does a fire rating on a safe actually cover?
A fire rating covers only what the test measured, and on most large cabinet safes here that means the bag, not the cabinet. The Mitlvge, both FOWORE models and the Homirxan all ship with a fireproof document bag instead of a rated box.
The bag specs matter. The Mitlvge bag is rated for 30 minutes at 1700 F and made from silicone-coated fiberglass.
That protects letters, cash and passports during a fast house fire. It does not protect a laptop, a hard drive or a photo album that will not fit inside.
The SentrySafe HD4100 and SFW123DSB and the Amazon Basics safe put the rating on the cabinet. The HD4100 is UL Classified for 30 minutes, the SFW123DSB for one hour at 1700 F and the Amazon Basics safe for 60 minutes, tested by Intertek.
The RXUJYC claims 35 minutes on the cabinet. That is shorter than the SentrySafe SFW123DSB and the Amazon Basics safe, but longer than a bag alone.
How much water protection do you get?
Water protection varies more than fire protection here. Only the SentrySafe SFW123DSB and the Amazon Basics safe carry a tested water rating, both for 24 hours in up to 8 in of water.
The SentrySafe HD4100 is ETL Verified for water exposure without the same depth-and-time figure.
The steel cabinet safes handle water through their included bag. That keeps documents dry if the bag stays sealed and above the water line.
It does nothing for the cabinet or for electronics inside it.
If your safe sits in a basement, a ground-floor room near a river or a garage that floods, choose a cabinet with a tested water rating. A bag is a backup, not a replacement.
Cabinet rating vs bag protection: which one do you need?
Choose a cabinet rating when you store electronics, photos or anything that will not fit in a bag. Choose a bag when paper and cash are the load and you want more space per dollar.
If you need both, buy a rated cabinet and add a bag inside it for extra paper protection.
How much room does a large safe really give you?
Stated capacity is the least reliable spec in this category. The FOWORE 27.56"H claims 6 cu ft from an 11.81 x 13.78 x 27.56 in exterior.
The RXUJYC claims 9.2 cu ft from a 15 x 16.9 x 31.5 in cabinet. Neither figure lines up with the box size, so judge by the chamber dimensions and your largest item.
Depth decides more than total volume. A 14-inch laptop needs about 12 in of interior depth.
The Mitlvge lists an 11.4 in chamber depth, so measure your laptop with its sleeve before you count on it fitting. The FOWORE 27.56"H lists a 12 in chamber depth, and the RXUJYC lists 14.7 in.
Shelf count decides how you use the height. Three shelves, as on the Mitlvge and both tall FOWORE models, let you separate a laptop tier from a document tier from a jewelry tier.
A single shelf means tall items take the whole cabinet.
What fits in 3 to 5 cubic feet?
A 3 to 5 cu ft cabinet takes a laptop, a stack of document folders, a jewelry box and a few small electronics with room to spare. That is why the Mitlvge and FOWORE cabinets top this list for most homes.
Below 2 cu ft, plan for paper and valuables only.
Our guide to fireproof safes with shelves covers how shelf layouts change what fits.
Which lock and access type suits your household?
A keypad is the fastest lock for daily use and the easiest to share, but it depends on batteries and a code you have to remember. Every keypad safe here except the SentrySafe pair includes an external battery box and spare keys, so a dead battery does not lock you out permanently.
A dial lock, as on the SentrySafe SFW123DSB, needs no battery and no code. It is slower to open and harder to share.
The key lock on the HD4100 is the simplest option and the least convenient for frequent access.
A fingerprint lock, as on the RXUJYC, opens in one touch and is hard to share across a household. It also adds a failure mode you cannot override with a code alone, so keep the emergency key outside the safe.
Keypad, dial or fingerprint?
Pick a keypad for a family that opens the safe daily. Pick a dial or key lock when you want no batteries and no code to forget.
Pick a fingerprint lock for quick personal access, and store the backup key somewhere separate from the safe.
Where should you place a large fireproof waterproof safe?
Place the safe on a ground floor or in a basement room that stays dry, and bolt it down if the room is reachable from outside. Weight matters as much as location: an 86 lb SentrySafe SFW123DSB or a 76 lb RXUJYC is hard to carry, while a 38.8 lb cabinet is easy for two people to lift.
Bolting changes the theft picture more than weight does. Most picks here include pre-drilled holes and expansion bolts.
The RXUJYC has no mounting holes, so place it somewhere a thief cannot easily reach rather than relying on its weight alone.
Heat and water move upward and spread through rooms. Keep the safe off the floor in a flood zone if the cabinet lacks a water rating, and away from a furnace or water heater.
A closet on an interior wall is a better spot than a garage corner.
Wall mount or floor mount?
Floor mounting is the stronger choice for a heavy cabinet, because it stops tipping and carrying. Wall mounting suits a lighter cabinet in a closet where floor space is short.
The Homirxan is wall mount only, so plan its spot on a stud wall.
The verdict: which large fireproof waterproof safe should you buy?
Buy the Mitlvge 23.62'' Tall Extra Large Home Safe if you want the most usable space and shelves for the money. Its 5 cu ft cabinet and three shelves handle documents and valuables, and the included bag covers paper during a fire.
Measure a laptop against its 11.4 in chamber depth first.
It is the best large fireproof waterproof safe for a typical home where theft is the main worry and fire is a backup concern.
Buy the SentrySafe SFW123DSB or the Amazon Basics safe if tested fire and water protection is the priority. Both carry cabinet ratings for fire and 24 hours of water protection, and the SFW123DSB adds a fall test and a replacement promise.
Choose the Amazon Basics safe for the tested water rating on a budget and the SFW123DSB for the smaller footprint and dial lock.
Buy the SentrySafe HD4100 for paper only in a small space. Buy the RXUJYC when you cannot drill and want a rated cabinet with fingerprint access.
Buy the Homirxan when the room, not the load, sets the limit. Whichever you pick, match the safe to the threat you actually face: theft, fire or flood.

Frequently asked questions
What does fireproof mean on a large safe?
It means the safe or a bag inside it is rated to keep contents below a set temperature for a set time during a fire. Most large cabinet safes here carry no cabinet fire rating and instead include a fireproof document bag rated for 30 minutes at 1700 F.
Only the SentrySafe models, the Amazon Basics safe and the RXUJYC claim fire protection on the cabinet itself.
Is a fireproof document bag enough without a rated cabinet?
A bag helps protect paper and cash during a short, hot fire, but it does not shield a laptop or hard drive from heat the way a rated cabinet does. Use the bag for documents and keep electronics in a cabinet with a fire rating if that matters to you.
How much water protection do these large safes offer?
The SentrySafe SFW123DSB and Amazon Basics safe are tested by ETL and Intertek for 24 hours in water up to 8 in deep. The Mitlvge and FOWORE safes rely on an included waterproof bag rather than a tested cabinet seal.
For a basement or flood zone, choose a cabinet with a tested water rating.
Can I bolt a large fireproof safe to the floor?
Most picks here include pre-drilled holes and expansion bolts for wall or floor mounting. The RXUJYC has no mounting holes, so it cannot be bolted down.
Bolting matters most when the safe sits on a ground floor or in a rental where a thief could carry it out.
How big a safe do I need for documents and a laptop?
A 14-inch laptop needs at least 12 in of interior depth, so a cabinet 12.2 in deep or more works. The FOWORE safes fit a 14-inch laptop and leave room for document folders, while the Mitlvge lists an 11.4 in chamber depth that may not fit a 14-inch laptop.
For paper only, a smaller file box such as the SentrySafe HD4100 is enough.
Do large fireproof safes need a power outlet?
The keypad safes run on batteries, so no outlet is needed. An external battery box lets you power the keypad from outside if the internal batteries die.
Keep the override keys somewhere away from the safe, not inside it.
