A recessed medicine cabinet is called one because it is designed to fit inside a hole cut on the get-go on drywall or plaster. It keeps the cabinet snug into the wall framing leaving the depth invisible and only the front trim and door embossed and visible. 

This allows homeowners to save space in their bathroom layouts which is efficient for smaller spaces; however, the catch is that recessed medicine cabinets are only available in the standard depth of 4 inches or 10 centimeters, nothing deeper.

The width and length can vary from one to the other, but the range is generally the same: 16 to 24 inches or 41 to 61 centimeters in width, while the length can stand from 20 to 40 inches or 51 to 102 centimeters. 

How To Measure Medicine Cabinet Size

In order to ensure that the chosen cabinet will be perfect for the space, busting out the measuring tape is needed to specify how a medicine cabinet will fit into the room. This calls for measuring the width, height, and depth of the vanity or the bathroom sink. 

The first is the width, and this calls for measuring the homeowner’s vanity space. Once this is measured, the medicine cabinet will be the same width or something narrower than the dimension. 

The second is the height measured by taking the tape measure and calculating the distance between the lights on the wall down to the faucet. There should be considerable space between both fixtures, and the cabinet should be a few feet higher than the top of the toilet. 

The last is the depth which is solely decided by the homeowner and will depend on how much usable space they want. This will extend from the wall.
