If you’re looking for something that can easily be hidden, a floor safe may be the way you want to go. Floor safes are a great way to keep your important documents out of harm’s way. However, while a floor safe may be heat resistant it is not water resistant. Your paperwork may survive the fire but it will not survive the water from the fire department. We would suggest you put everything in air-tight bags or air-tight plastic boxes. If you are putting this in your garage, cement will allow water to seep through, we would suggest that you wrap the body of the safe in thick plastic. Floor safes are also one of the hardest safes to break into with the sides being surrounded by the ground and the door made of thicker steel.
