Q: Are wall safes waterproof?

A: No, wall safes are not watertight and are not waterproof. We recommend putting your items in zip lock bags or Tupperware containers if you want to keep them 100% waterproof. You can also buy a fire- and water-resistant bag to put your items inside. This bag sits inside the safe protecting your items. It comes in two different sizes. Both are designed to hold standard sheets of paper.
