Homemade Floor Safe

By Brittiany Cahoon
Floor safes keep your valuables more secure.

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

Step 1

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.

Step 2

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.

Step 3

Use the shovel to dig deeper into the hole. Make the depth of the hole 3 inches more than the height of your safe.

Step 4

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.

Step 5

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

Step 1

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.

Step 2

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.

Step 3

Set the safe into the hole and secure it with cement using the same process as you would on a concrete floor.
