What size medicine cabinet should I get?
Reviewer consensus
Most reviewers recommend matching cabinet width to the vanity below it (or slightly narrower) and centering at eye level. Common sizes in this roundup range from 14x18 inches for half-baths up to 30x26 or 36x30 for primary vanities. Double-door units (like the Kohler CLC3026FS) make sense for wider single vanities; tall single-door units like the Kohler Archer work for narrower walls.
