How thick does the wall need to be for a wall safe?

The minimum wall thickness is the depth of the safe itself plus at least 10 cm of concrete at the rear, plus any finishing at the back. For most wall safes, this means you need a fairly thick wall. If your wall is not thick enough, a freestanding safe anchored to the wall or floor is often the better solution. See our home safe page or explore our range of wall safes and floor safes.
