If you’re looking for a small fireproof safe to fit just a few vital documents, this compact option from SentrySafe will do the job. It’s designed to withstand temperatures of up to 1,550°F for half an hour and has a capacity of just 0.18 cubic feet, with a built-in handle that makes it easy to take with you.

One satisfied customer shares, “I’ve owned [this] safe for 20+ years…It’s the perfect size to slide under the bed or put on a closet shelf. Reliable and great quality!” More than 19,000 Amazon users give this Sentry fireproof safe a 5-star rating. “EXACTLY what I was searching for,” another reviewer writes. “Something stable but yet light enough to pick up and go if the need be. It can be stored inside a cabinet or closet out of sight.”

And even though it’s conveniently portable, if the wrong person gets their hands on it, they’ll run into serious trouble trying to open it without the key.

Amazon Basics isn’t just for paper plates, bath towels, and batteries. You’ll find that label on the site’s most popular safe, too, which has more than 36,000 5-star reviews. The largest size, which offers a capacity of 2.13 cubic feet, is a fireproof safe box. In addition to security features like live-door bolts, concealed hinges, a programmable lock, and wall-mount hardware to keep prying hands out of your business, it’s also certified to endure temperatures of 1,700°F for up to one hour. The safe is waterproof as well, so if a fire triggers your automatic sprinkler system, you’re covered there, too.

Reviews for this safe praise everything from the sturdiness of the build to how easy it is to use. “Highly recommend if you’re looking for a simple and reliable safe!” says one user. Another comments, “Big enough and heavy enough that it won’t be easily stolen if not bolted down. Sizable enough for all our household documents, receipts, insurance and investment paperwork. Hopefully I never find out if it’s as fireproof as they claim.” We couldn’t agree more.

One of the most durable fireproof waterproof safes you’ll find, this Sanctuary Diamond option can handle temperatures up to 1,800°F for 90 minutes. It will also stay watertight for a whopping seven days in standing water (as long as the water level stays below the handle). It even comes with a lifetime warranty for theft, fires, and floods—the items inside aren’t covered under the warranty, but the safe itself is.

Interior lighting helps you see what’s inside even if you keep the safe tucked away in a dark closet, and the inside is lined with carpeting to protect your delicate valuables from damage. In addition to industrial-grade steel construction, the safe prevents against theft with a timeout lock to thwart anyone who tries to break in too slowly.

“This is so well built and solid! You can definitely tell the difference between this safe and many others,” one customer comments. “The door itself is sooo much thicker than a normal safe and the locking mechanism is very user friendly. Looks like I’ll be using this safe to protect all my valuables for years to come!!”

Measuring 19.3 inches deep x 16.3 inches wide x 17.8 inches tall, this Sentry fireproof safe has a 1.23-cubic-foot capacity. It also weighs a whopping 90 pounds, which means that it’ll ultimately be extremely difficult for an intruder to take it without putting in some serious effort. Adding to the security factor, this fireproof document safe features four live-locking bolts, pry-resistant hinges, steel construction, and hardware to bolt it to the floor.

“I don’t usually write reviews but in this case I wanted others to know what a great product this is,” reads one review. “I am very happy with this purchase and recommend this safe very highly. No negatives to report.”

For floods and fires, this safe is verified to remain watertight for 24 hours and withstand temperatures of 1700°F for up to one hour. It’s even guaranteed to stay locked if it’s dropped from as high as 15 feet!
