For the greatest level of security, a safe should be installed into the wall or the floor. Safe installation charges will vary according to what is underneath the safe. If placed in concrete, the safe will not only be highly burglar resistant but will also be beyond the reach of most fires. Unfortunately, safe installation in these cases can be quite costly, often exceeding $600.

A less expensive solution is to bolt a safe to the floor. However, this does not provide any extra protection from fire.
