Step 1: Place the Cabinet

Installation of the preassembled medicine cabinet is made easier by first removing the mirror and door from the framework. In our case, this was simply a matter of removing two screws from the door hinges and carefully lifting off the door.

With the door and mirror removed, the medicine cabinet is carefully placed into the precut rough opening (Image 1) left earlier by the carpenters and drywall installers. The assembly is pushed back until it's seated firmly in the opening and flush with the drywall.

A 2' level is used to check and ensure that the cabinet is straight and level (Image 2).

Step 2: Attach the Cabinet

The cabinet is secured in the opening with wood screws. Pilot holes are first drilled through the side walls of the cabinet and into the wall stud underneath, using a 1/8" drill bit. Screws are then inserted with a Phillips-head screwdriver attachment on a cordless drill.

The steps are repeated for the installation of the second medicine cabinet in the master bath.
