Recessed or surface mount: which medicine cabinet fits your wall?
A recessed medicine cabinet sits inside the wall, so it fits only where the cavity behind the opening is clear of plumbing, wiring and venting. A surface-mounted medicine cabinet hangs on the face of the wall. Start by finding where the wall studs are and measuring the distance between them.
What size opening does a recessed medicine cabinet need?
A recessed medicine cabinet needs the rough opening its own specification sheet or installation guide gives, which is the opening cut into the wall to fit the cabinet, with a width, a height and a depth. Published openings differ between cabinets, as the three examples below show, so read the figures for the cabinet in question before buying.

These are manufacturers' published figures, given as examples, not a list of what BVX has.
Which way should a medicine cabinet door open?
A medicine cabinet door should open clear of everything around it. Hold the cabinet in place, open the door and make sure nothing such as the faucet or the vanity lighting is in its way. Some cabinets can be installed with a left- or right-hand swing, and some can be turned over so the door opens the other way.
What power does a lighted medicine cabinet need?
One maker's guide for a lighted medicine cabinet requires a 120 V, 15 A circuit with GFCI protection and a qualified electrician to route the wiring. The guide also says electrical wiring may need to be relocated, so read your cabinet's guide and check the wall for that supply first.
What to check on a medicine cabinet at pickup
Look at the mirror on the door for cracks and along its edges for chips. Check the door, whether attached or packed loose, for its hinges, present and tight. Look over the cabinet body's corners for dents. Count the shelves and their clips against the listing, and check every other part the listing names, including any side mirror kit for surface mounting.
Medicine Cabinets is part of the bathroom range. For a mirror with no storage behind it see Bathroom Mirrors, and for the cabinet under the sink see Bathroom Vanities. The inspection guide and the pickup planning guide cover the rest.
