Many bathroom doors are cut a little short on the bottom to let air

As far as I know, all interior doors should have a 1/2-3/4" gap on the
bottom for air circulation if you have forced air HVAC.

No need if you have an air return in that room.



True, but the most places I've seen they don't exactly load all the BR's
with returns.
