10 Best Fireproof Box 2026 in the United States

This Amazon Basics fireproof safe is designed for home use, offering solid protection against fire and water damage. It meets a high fire rating standard, able to withstand 1 hour at 1700°F, which is a strong level protecting most important documents and valuables during a house fire. The box also keeps contents dry underwater for up to 24 hours at 8 inches deep, providing good water resistance in case of flooding.

With a capacity of 2.13 cubic feet and dimensions of 24" high by about 21" wide and 19" deep, it provides a decent amount of storage space for important papers, small electronics, or jewelry. Inside, it includes a removable shelf and drawer, helping keep items organized. Security is reliable with a preset digital electronic lock featuring six live-locking bolts and pry-resistant dead bolts, making it difficult to break into. The heavy steel construction and included bolt-down hardware add to its sturdiness and theft deterrent.

Due to its weight of over 136 pounds and design for floor mounting, this safe is not portable or easy to move once installed. This model is a strong choice for homeowners seeking a durable, fireproof, and waterproof safe with secure locking and practical internal organization, best suited for a fixed location.

This fireproof box from FOWORE offers a large 6 cubic feet storage space, making it suitable for protecting important documents, valuables, and small electronics at home or office. Its sturdy steel construction with a thick 50mm door and 20mm locking bolts provides strong resistance against fire and physical tampering. The programmable digital keypad with backup keys and an external battery option allows flexible access, while the built-in burglar alarm adds extra security with a silent mode feature for discretion.

Internal organization is well thought out, with three removable shelves and LED lighting to easily organize and find items. Although it comes with a fireproof and waterproof document bag, the safe itself is noted as not water resistant, so full water protection depends on using the bag. The safe weighs 41 pounds and can be mounted to a wall or floor for added theft prevention, but it’s not designed for frequent portability.

For anyone needing a sizable, secure, and fire-resistant safe primarily for home or office use, this model covers most bases well. If water resistance of the entire safe or lighter weight for portability is a priority, this product may have limitations.

The ENGPOW 5200°F Fireproof Document Box is designed to protect important papers and valuables from extreme heat and water damage. Its standout feature is the high fire rating of up to 5200°F, thanks to its thick silicone-coated cotton and aluminum foil lining, which has passed safety tests and won’t easily melt. This makes it a reliable choice for safeguarding documents in serious fire situations. The box measures 15.55 by 12.2 by 10 inches, providing enough space to hold both letter and legal-sized files, as well as smaller valuables like passports, USB drives, and CDs. Inside, you’ll find mesh pockets that help keep things organized.

A practical touch is its collapsible design, making it easier to store when not in use, and the sturdy adjustable handle adds to its portability for moving it around your home, office, or car. Security is enhanced with a mechanical combination lock, eliminating the need for keys, though this requires remembering your code. The box also resists water and dust, which adds extra protection in case of accidents. The zippers and reflective strip are thoughtful details for convenience and visibility.

At about 3 pounds, it’s light enough to carry but solid enough to hold up to 150 pounds without warping. While it offers excellent fire and water resistance, combination locks can be tricky if you forget the code, and its size may be larger than what some need for simple document storage. This box provides dependable, portable protection for important documents and valuables, combining durability, security, and organization features.
