Fixture clearance from walls
FIX-FIXTURE-CLEARANCE-01Description
Adjacent fixtures need at least 4 inches of separation unless they're explicitly counter-joined (double-sink vanity).
Why this exists
Every fixture has a manufacturer-specified front and side clearance. Forcing a vanity flush with a wall makes the door unopenable.
