the.com/restroom

The one room where lying about being 'busy' is architecturally guaranteed privacy.

means A room in a public or workplace building with a toilet, used as a polite catch-all term rather than naming its actual function.

from An early-1900s American euphemism — 'rest' standing in for the room's real purpose, in the same genteel tradition as 'bathroom' for a room with no bath and 'powder room' for one with no powder. It caught on because English has always preferred to tiptoe around bodily functions with comfortable fictions.
