This is an area where UK and US English are very different! There is no such word as "faucet" in the UK (we say a tap) - a "rest room" is where one goes to lie down - a toilet is definitely NOT a bathroom.
For some reason US Americans seem rather squeamish about bodily functions, the English rather less so while the French are entirely open.
Where do the Dutch stand on this delicate subject?
Here the toilet is 'de wc' or 'het toilet'. The bathroom is 'de badkamer', the room where you take a bath.
