It's important to protect your valuables, but a portable safe can be cracked or just taken by thieves to be cracked later. A floor safe is a permanent and secure storage device that can be built right into your home and hidden from potential burglars. Installing a floor safe takes some work, but you'll have the satisfaction of knowing that your valuables are much more secure than they would be otherwise.
Install a Safe into a Concrete Floor
Decide what type of lock you want on your safe. Purchase a safe that is made to be installed into the floor. Remove the door of the safe and tape a dust cover over the opening with masking tape to keep water and cement out of your safe.
Use chalk to draw a square around your safe, leaving 4 extra inches of space around the perimeter. Drill through the concrete in the outline using the electric jackhammer.
Use the shovel to dig deeper into the hole. Make the depth of the hole 3 inches more than the height of your safe.
Line the sides of the hole with plastic sheeting. Pour wet concrete into the hole to form a level base for the safe to sit in.
Place the safe in the hole. Pour concrete into the rest of the hole and use a trowel to level the wet concrete with the rest of the floor. Use scissors to trim away excess plastic when the concrete is dry.
Install a Safe into a Wooden Floor
Cut a hole in the floor the shape of your safe, allowing 4 extra inches of space on each side. Build a basket matching the dimensions of the hole out of mesh wire and line it with roof paper.
Attach the basket to the joists between the wood floor and the ground. Reinforce the joists to hold the weight of the safe, if necessary.
Set the safe into the hole and secure it with cement using the same process as you would on a concrete floor.
