For years and years I assumed that by '
Restroom' Americans were referring to a place with large, comfortable armchairs, where tea and coffee etc were available, and where one went to relax. I was astonished to discover recently that it was a TOILET!!
Then last night I was watching an old episode of the UK sitcom
Are You Being Served?, and the ridiculous term
Powder Room was used three times.....

Restroom, bathroom, men's room/ladies' room, facilities, potty...pretty much nobody in America would refer to the bathroom as the "toilet", which is usually reserved only for the toilet toilet (you know, the thing you poop in!). Lavatory, loo, washroom...those are rarely heard in the US and I've never heard anyone use "water closet" ever.
"Powder room" is super-outdated, but I've actually heard elderly folk refer to it as such before. I believe it's exclusively referring to the ladies' room, back when "I've got to powder my nose" was an actual polite euphemism for "I've got to go to the bathroom". God forbid men discover that women actually pee.
I've also heard "comfort station" as a term for restroom, which I think is delightful.
