We researched dozens of options on the market and chose standouts based on size and weight, protection from the elements, and added security features.

Here are the best fireproof safes for your home.
SentrySafe Fireproof and Waterproof Safe with Digital Keypad
Protects up to 1700 degrees Fahrenheit
Waterproof for up to 24 hours
Multiple layers of security
Keypad requires batteries
A bit expensive
You’ll see plenty of SentrySafe options on our list, because they are high-quality and reliable, and they will help keep your valuables safe. Earning the top spot on our list, this safe can protect its contents from fire and heat, up to 1700 degrees Fahrenheit, for up to one hour. In many cases, that is enough time to allow emergency personnel to respond and put out a fire before your documents and valuables are in danger. It also stays watertight for up to 24 hours, whether your house experiences flooding or you are dealing with the aftermath and cleaning of a fire response or other emergency.
It uses a digital keypad to lock and unlock the safe as well as a secondary key. Plus, there is another compartment within the safe that can be locked with a key for two layers of security. It is relatively small and designed for your most valuable and irreplaceable items. In fact, at 1.2 cubic feet and 87 pounds, this safe is small enough to fit in a closet or another out-of-the-way place.
You can bolt it down using the included kit, but that is not required. It's a bit pricey compared to similarly sized safes, but because it protects against multiple elements and has multiple layers of protection, we think it's well worth the cost for the added peace of mind. If you are going to buy one safe for your important documents and valuables, this is an excellent choice.

Anchoring hardware included
Very heavy and hard to move

It is compact and best for only your absolute essentials, such as irreplaceable documents and photos.

Sanctuary Platinum XSmall Fireproof and Waterproof Wall Safe
Superior fire rating
Waterproof for up to seven days
Not great for a lot of documents
This safe can withstand hot temperatures for up to an hour and water for up to seven days. With such great protection, you would expect it to be much more expensive than its budget-friendly price. It has an illuminated touch keypad for opening, so you never have to worry about fumbling with a key or seeing a dial when your home has been damaged by fire or flooding.
The safe is on the smaller side and best for small valuables, a few documents, and items like passports. If you want to store more papers and files, you will have a hard time with this safe, even if you take out the removable shelf. It does technically fit a standard 8.5 x 11 document on the bottom, but you won’t have much extra room.

Best for Documents
SentrySafer 1170 Fireproof Box with Key Lock
Sized for document folders
Easy to access important documents
Can be purchased with or without files
Not ideal for non-document valuables

You can also opt to get a package that includes file folders or a document shredder for added savings and to keep your important documents and personal information secure.
It is rated for 30 minutes of fireproof protection up to 1550 degrees Fahrenheit and uses a key to lock and open. And at 28 pounds, it is light enough to move as needed. Note that this box is not waterproof, and keep in mind that if you do store your documents in hanging files, it can make it harder for other valuables to fit or be easily seen in the safe.

Tigerking Safe Box
Keyless entry and two backup keys
Adjustable inner shelf
Fits legal-sized documents
Fire ratings are lower
You never need to worry about remembering where you stored your key or keeping track of it in an emergency with the Tigerking safe box. It uses a digital lock instead. In fact, this safe box comes with two emergency keys that you can keep at a safe distance for backup. It is double-hinged so that even if the outer hinge is breached, the inner one will keep the safe from being opened.
The fire rating is not as great as some other safes, protecting up to temperatures of 1200 degrees Fahrenheit for up to 30 minutes. It is also not waterproof. The larger size is a perk of this safe, however, as is the adjustable interior shelf. It can even fit legal-sized documents.

Comes with a fireproof document sleeve
Removable shelf and Interior locking drawer
Not enough space for large items
This large safe has a 2.1 cubic foot capacity, providing enough space to store documents, valuables, and keepsakes. It protects against fire and heat as well as break-ins. When triggered, the alarm vibrates and makes an audible sound. If it is struck with enough force, the vibration alarm is triggered. If the wrong password is entered three times, the audible alarm sounds. It stops after 60 seconds but remains active until the right password is entered.
You can set it by using the included key, keypad, or battery box and open it using any of these methods. It does require a battery to operate the keypad, however. The safe gives you a low battery notice when it is time to replace the battery. Plus, it comes with a fireproof envelope for your documents, an interior drawer with a separate key, and a removable shelf. It isn’t ideal for storing large items but works for important papers as well as other valuables.

The interior is carpeted to keep your valuables protected and padded. You can also use it as a gun safe. It weighs 217 pounds, so it likely isn’t going to be moved much once you get it in place.

What to Look for in a Fireproof Safe
It’s to be expected that a fireproof safe box will withstand high heat and flames, but not all safes are created equal. Some carry minimal fireproof ratings and can’t take the heat for more than 30 minutes before becoming damaged. Many models are rated for an hour of fire exposure, while the most robust safes carry a two-hour fireproof rating. Some fireproof safes are also waterproof or have been drop-tested.
Fireproof safes come in a range of different weights, which impacts how portable they are. Some larger safes can weigh 100 pounds or more—this can be a great deterrent for thieves but not so great if you want to take your safe on the road. If you’re looking for a fireproof safe that's easy to take with you, you’ll likely want to pick one that weighs less. Many portable versions weigh between eight and 15 pounds.
Choose a sturdy locking mechanism for your fireproof safe to ensure that the contents stay secure. There are traditional lock-and-key closures, but there's a risk that you may lose the key. Other fireproof safes have a keypad that allows you to enter a passcode to unlock the safe. Finally, some safes have a combination lock that eliminates the concern of lock-picking that comes with having a keyhole.
What are fireproof safes made of?
The most effective fire-resistant safes have a double-walled construction, with two sheets of steel and a layer of fire-retardant materials in the middle. Fire-retardant materials may include cement, gypsum, perlite, vermiculite, or diatomaceous earth, depending on the manufacturer. Cheaper fireproof safes have plastic interior walls covered with fireproof material. Well-made fireproof safes also include a strong seal that swells to keep the door firmly shut to keep out flames in the event of a fire.
Will paper money burn in a fireproof safe?
If the safe doesn’t have a high enough fire safety rating, it just might. If you’re keeping cash in a safe, do yourself a favor and make sure the safe has a high fire safety rating so that you have the best chance of protecting your money (and other important paper-based items) from bursting into flames. While some people feel better having a wad of cash money stashed in a personal safe, your money is probably more protected from fire when stored in a bank or credit union.
Are all safes fireproof?
No safe is entirely fireproof, but safes have varying degrees of resistance against damaging elements such as fire (and water), so be sure to read the fine print to find out just how fireproof (or waterproof) a safe is before you purchase it. Individual safes may keep your valuables from burning for as little as 30 minutes or as long as two hours, depending on the make and model. If you are storing irreplaceable items, documents, or paper money in your safe, do yourself a favor and invest in one with the highest fire safety rating you can afford to protect your valuables in case of a fire.
