Fireproof safes can stop a fire or break-in from escalating from terrible to truly disastrous by keeping essential documents like birth certificates, Social Security cards, and passports safe from destruction or theft. These have at least 30 minutes of fire protection and the durability to keep thieves out. They’re also a good way to organize and keep track of sensitive information in your home as part of your home security system.

Useful features range from biometric locks and backup locks to alarms and water resistance. Wondering ‘what is the best fireproof and waterproof safe for home use?’ Your budget, capacity needs, and available space will help determine which fireproof home safe is suitable to keep your valuables secure. Each of the top picks below was selected after an in-depth review of the market and thorough product vetting.

Fire and theft are at the top of most people’s home security concerns. Some safes offer better protection from one than the other. Water damage is another issue at the top of many people’s minds, and there are safes that offer some water resistance in addition to their other protective capabilities.

Ultimately, the items you want to protect and what or whom you want to protect them from help determine the right capacity, locking mechanism, and fire rating for your safe.

Most safes are made of thick steel sheets. The sheets, which can be several centimeters thick, give safes their hefty weight. However, these aren’t just any sheets of steel. Safes contain plates made from both hard steel and mild steel. Heat can cause hard plates to crack, exposing the contents to hot temperatures. Mild steel warps rather than cracks, protecting the contents even as temperatures rise.

Fire safes are also constructed with a layer made of a nonconductive composite material that prevents the interior temperature from rising for 30 to 120 minutes. Fire-resistant insulation is also often used to help keep those interior temperatures down.

However, steel isn’t the only material used to make fireproof safes. ABS plastic and various resins are used as well. These two materials are lighter weight and are typically used to make smaller, more portable safes.

Start your search for a fireproof safe box by making a list of what you want to keep inside it. If you have valuable jewelry or other irreplaceable items, a bank lockbox offers the best protection.

Passports, birth certificates, Social Security cards, insurance policies, and tax returns are also valuable documents that could pose a problem if lost to theft or fire. Take a look at your list and make sure the safe will hold everything on it. For example, firearms take up more space than documents or DVDs.

Size also plays a role in where you can put the safe. Obviously, a fireproof wall safe or a large safe is harder to hide and easier to spot. If you want to keep the safe hidden, consider a small fireproof safe that more easily fits in a closet, crawl space, or under floorboards. Keep in mind that small safes are vulnerable to theft if they’re not hidden.

In truth, no safe is 100 percent fireproof. Safes are fire resistant only up to a certain temperature and for a certain amount of time.

Underwriters Laboratories (UL) evaluates safes and gives them a fireproof rating. These ratings indicate two things—the maximum temperature at which the product can maintain a safe interior temperature, and the length of time the safe can hold that temperature.

The interior temperature determines the kinds of materials the safe can protect. For example, the interior of a paper document safe shouldn’t get hotter than 350 degrees Fahrenheit. Anything above that, and the paper will burn. However, electronics may not be able to withstand temperatures of more than 125 to 150 degrees.

The UL rating also indicates how long the safe can hold that interior temperature. Most home fireproof safes offer at least 30 minutes of protection. That may not sound long, but most fires move through a room in less than 20 minutes. For additional peace of mind, however, some safes offer up to 120 minutes of fire protection.

Waterproof safes indicate how long they can protect their contents from water as well as the depth at which they can maintain that protection. Most resist water for approximately 24 hours, but some may offer up to 72 hours of protection in water that’s 8 to 40 inches deep.

If you live in a flood-prone area, it’s a good idea to put the contents of the safe in waterproof bags, whether the safe is rated for water protection or not. Some safes also offer humidity resistance, which can protect items or documents that are sensitive to subtle environmental changes.

Usability features include display visibility, weight, and the safe’s overall portability. LED displays are much easier to see in dim conditions. Considering that safes are often stored in dark, secure areas, a display that’s easy to see will make the safe more functional.

Some safes are portable with a top or side handle for easy carrying. These small safes may weigh 25 to 30 pounds. Others weigh more than 100 pounds and would take two people to move.

Fireproof home safes can weigh anywhere from 20 pounds to hundreds of pounds. The ideal safe weight depends on several factors, including portability and intended location and use.

If portability is a concern, look for a lighter safe, weighing under 30 pounds. These safes will be easier to take along when traveling or commuting. They’re also usually smaller and made to store items like USB drives, cash, passports, and other important documents you may need to carry with you.

Lightweight safes are easier to carry—both for you and a possible burglar. For larger or freestanding home safes, a hefty weight can work to your benefit; it’s harder for a robber to make away quickly with a safe that weighs hundreds of pounds.

The items you want to protect, your available space, and the threats from which you want to safeguard your items will help you determine the right safe for you. Here are a few more tips to help you find the best fireproof safe and incorporate it into your home security system.

The safes on this list offer a wide range of features and perform well under UL or ETL testing. Some models have extra features like alarms, while others offer biometric entry. We used fireproof safe reviews and user experience to critically examine the features and benefits of the top fireproof safes to select options to meet a variety of needs.

The SentrySafe SFW123GDC ticks all of the boxes for the safekeeping of sensitive items. Its UL rating indicates that it can keep its 1.23 cubic feet of interior space at a safe temperature for paper documents, DVDs, and USB drives for up to 60 minutes in temperatures up to 1,700 degrees Fahrenheit. The SFW123GDC also resists water for 24 hours in depths up to 8 inches.

Burglars will have a hard time cracking this egg since it can also withstand a 15-foot drop without breaking. The safe also comes with bolt-down hardware to secure it from thieves. You can set your own combination on the digital keypad but also have the assurance of access with a backup key.

On the interior, a locking drawer and shelves organize your documents and valuables, with interior lights that illuminate contents in the dark. At 86.3 pounds, this model is not lightweight. It requires four AA batteries to run the lock mechanism and interior light.

The Sanctuary Platinum features a safe within a safe construction. The exterior shell can withstand fire up to 1,800 degrees Fahrenheit for 60 minutes. The interior compartment, however, can withstand the same temperature for up to 120 minutes. Organizers in the door add storage space, and these, too, are fireproof. A triple seal design also protects contents for up to 7 days in 4.5 inches of water.

Any tampering will set off an audible alarm. When it’s time to get into the safe, an illuminated keypad offers reliable access. In an emergency (e.g., you forget the code), it comes with two backup keys.

Though this safe is on the smaller side, it has three locking bolts and comes with predrilled holes to fit the included bolt kit. The safe remains fireproof if it’s not bolted down. However, it loses its waterproofing if the bolt kit isn’t used.

SentrySafe offers a wide range of fireproof safe options worth looking into. We liked the SentrySafe SFW123GDC for its combination of interior space, entry options, and price. However, if you only need a fireproof safe for documents, a mini safe might fit the bill, and the First Alert 2030F is a highly affordable alternative offering 0.39 cubic feet of storage while still providing excellent fire security.

We spent hours researching fireproof safes because they come in a wide range of styles and designs, with varying levels of security to protect from theft, fire, and/or water. We started by looking for safes with maximum temperature ranges above 1,500 degrees Fahrenheit with at least 30 minutes of fire protection.

From there, we considered construction. Does the safe have a live locking bolt? How many? How are the hinges designed? (Exposed hinges are easy to break into.) How many layers make up the fire protection? (It often takes several layers of materials, including thick steel, to stop high temperatures from damaging valuables.)

The locking mechanism also played an important role in our choices. The locking mechanism should be secure enough to deter thieves, though fireproof safes are better at fire protection than protection from burglary. Safes with more than one kind of entry mechanism, like a combination lock with a key, also got higher marks from us. It’s always good to have a secondary locking key in case of an emergency.

A fireproof safe is a good place to store important belongings you want to keep at home, while a safety deposit box is best for really important items that you don’t use often. A home safe will keep items protected but also within easy reach, in case you need to access or use the contents inside. Some items to store in a fireproof home safe include:

Fireproof safes aren’t particularly complicated. But if you’re new to them, you probably have a few questions. We’ve got the answers to common questions along with tips to help you better protect your sensitive information and belongings.

It depends on the safe’s level of protection. If the house fire does not exceed the safe’s maximum fire-resistance time or temperature limit, it will survive the fire.

Look for a UL-listed or ETL verified safe; these safes have undergone trusted third-party testing based on design and performance standards.

Not all safes are fireproof. Some safes are designed specifically to deter theft, while others may protect from water damage rather than fire or theft. Some protect from all three. If you want a safe that protects from fire, you need to specifically look for one designed for that purpose.

It depends on the safe, so look at the displayed specifications. Many fireproof home safes can withstand temperatures over 1,000 degrees Fahrenheit.

A UL fire rating comes from the Underwriters Laboratories and is a rating of temperature and time. This organization tests safes to determine the maximum exterior temperature at which the safe can hold a safe interior temperature and for how long it can maintain that temperature. Be sure to buy a safe that’s “UL listed,” not “tested to UL standards.” The former means the safe has passed the UL tests, while the latter means the safe has been submitted but has not yet passed the safety tests.

Intertek inspects and tests products for safety and gives an ETL verification for those that pass. Much like the UL, they test safes for fire and water safety. An ETL verification is also a good indicator of a safe’s overall quality and safety.

Not all fireproof safes have been tested against flooding, although many will offer some water protection. For reliable fire and flood protection, look for a safe that is both fireproof and waterproof.

Choose a safe with your preferred locking mechanism for ease of use and convenience; it’s more important to consider the protection level rather than the lock type when it comes to fire safety. A fireproof safe that has been certified to a certain standard (for example, 1,500 degrees Fahrenheit for 60 minutes) will protect its contents from those conditions for the advertised time, regardless of the locking mechanism.

The size of the safe will narrow down your options. Look for a low-traffic area that’s not easily seen or noticed. Someplace other than the master bedroom is a good choice since thieves usually start their search there.

A guest bedroom or hall closet are good options. However, avoid the garage or basement. Garages tend to be left unsecured and are an easy target for thieves to carry away a safe. Water easily floods basements, making them a less-than-ideal choice.

Determined thieves can steal and possibly open a safe despite complex locking mechanisms. A poorly-made safe may open when dropped only a few feet, for example. The more deterrents the safe offers, the more likely thieves are to leave it alone. An audible alarm may be enough to scare off a jittery burglar.

To hide a wall-mounted safe, choose a concealed spot, such as behind a door, furniture, a mirror or painting, or in the back of a closet.

Yes, bolting a safe to the floor offers extra security against theft.

Home safes don’t require much maintenance. Periodic checks for dust and moisture and the occasional cleaning can help to keep contents tidy and prevent a musty smell.
