The 8 Best Extra Large Fireproof Safes for Documents, Cash and Valuables, Ranked & Reviewed

Our verdict: A 35 minute rating at 1700 degrees F backed by a cited UL standard and SGS certification.

The Mitlvge 35-Min safe stands 23.4 inches tall and weighs 45 lbs. Its listing cites a UL standard and SGS certification for 35 minutes at 1700 degrees F, with 3 locking bolts of 0.98 inch and pre-drilled holes closed with fireproof sealing plugs.

It ranks first because a named test standard and a named certification body are the strongest evidence a listing can offer. The sealed pre-drilled holes show the maker thought about fire entering through the bolt-down points, which is where many safes leak heat. Weight is modest for an extra large safe, so bolting it down matters. It is the most expensive of the 5 cu ft class.

Buy it if a documented fire rating matters most. Skip it if you want maximum capacity.

Our verdict: 9.8 cubic feet and 124 lb with 8 locking bolts and fingerprint access with a key backup.

The biggest safe in this ranking offers 9.8 cu ft, weighs 124 lbs and has 8 locking bolts, 5 live and 3 dead. Access is by fingerprint with a key backup.

It takes second place because it combines capacity and mass: 124 lb is heavy enough to resist a casual walk-off, and eight bolts spread the load around the door. Live bolts move with the lock, and dead bolts sit fixed in the door, so both resist prying. The fireproof and waterproof claims in the title are not backed by a named standard in the listing we reviewed, so treat them as marketing until you see paperwork.

Buy it if you need to store firearms-sized or bulky items and want serious weight. Skip it if documented fire testing is your top need.

Our verdict: A 67mm reinforced door, four 20mm round bolts and three unlock methods with alarm lockout.

This 5.2 cu ft safe has a 67mm reinforced door, 4 round locking bolts of 20mm, three unlock methods and a tiered alarm lockout.

A 67mm door is the thickest listed in this ranking, and thickness is both a pry-resistance and an insulation feature. Tiered lockout means repeated wrong codes trigger longer delays and an alarm, which stops guessing. It ranks third because the listing gives no named fire rating, and a thick door is no proof of one.

Buy it if door strength and flexible access matter. Skip it if you require a certified fire rating.

Our verdict: 85 lb with a 35 minute fire claim at 1800 degrees F and sub-one-second fingerprint access.

This 31.5-inch safe weighs 85 lbs, claims 35 minutes at 1800 degrees F, and opens in under a second with a fingerprint reader that stores 29 prints. It ships with no pre-drilled mounting holes.

The lack of mounting holes is a stated tradeoff: it preserves the fire seal but means you cannot bolt it down without drilling yourself. At 85 lb it is heavy, but a determined thief can still move it. Twenty-nine stored prints suit a family or a small business. It ranks fourth because the fire claim names no standard.

Buy it if you want fast biometric access and a sealed body. Skip it if you must bolt it to the floor.

Our verdict: 5.0 cubic feet with a 50mm steel door and a bundled A4 fireproof bag rated 30 minutes at 1700 F.

The Mitlvge 5.0 cu ft stands 23.62 inches tall, weighs 38.8 lbs and has a 50mm steel door with 3 removable steel shelves. A bundled A4 fireproof bag is rated for 30 minutes at 1700 degrees F.

The bag is a thoughtful extra for passports and drives, but note that the 30 minute claim is for the bag, not the safe body. The safe itself offers a thick door at a modest weight. It ranks fifth because the body's fire rating is not documented separately.

Buy it if you want the bag included and a thick door. Skip it if you need a fire claim for the body itself.

Our verdict: A double-door independent design with a front deposit slot, four live bolts and a backlit keypad.

The Omethey has 5.0 cu ft, a double-door independent design, a front deposit slot, 4 solid live bolts and a backlit keypad.

The deposit slot lets cash go in without opening the door, a feature for small businesses and shared households. Double doors separate valuables from everyday items. The compromise is that independent doors add hinges and seams, and the listing lacks a fire rating.

Buy it if you drop cash or envelopes regularly. Skip it if fire protection is your top need.

Our verdict: 6.2 cubic feet with a 42mm door and three 20mm bolts at only 39.6 lb.

The 6.2 cu ft safe has a 42mm thick door, 3 locking bolts of 20mm and 3 removable steel shelves, at 39.6 lbs.

It offers the second-largest interior here, but at 39.6 lb it is lightweight for its size, which hints at thin body walls. The door is thinner than the Mitlvge's 50mm, and no fire rating is listed. Bolt it down if you buy it.

Buy it if you want maximum space on a limited budget. Skip it if you need documented fire protection.

Our verdict: A 4.0 cubic foot cabinet with two fireproof drawers, a 20mm bolt and a Type-C emergency power port.

The WASJOYE is a 56.11 lb cabinet safe of 4.0 cu ft with 2 fireproof drawers, a 20mm anti-pry door lock bolt and a Type-C port for emergency power.

The Type-C port is a thoughtful detail: if the batteries die, you can power the keypad from a power bank. Drawers organise small items. It ranks last because it is the smallest, with only one bolt listed, and the fire claim is unspecific.

Buy it if you want drawers for paperwork and a power backup. Skip it if you need a large interior.
