Synonym discussion

Sense: noun/1

'Bathroom' is the most neutral and common term in American English, used for any room with a toilet and sink. 'Restroom' is a polite public-facing term found in restaurants, airports, and offices — it avoids direct reference to bodily functions. 'Toilet' is direct and globally understood but can sound blunt in American conversation. 'Loo' is the British informal equivalent of 'john' — casual and friendly. 'John' is distinctly American slang and projects a casual, slightly old-fashioned tone; it works best in relaxed settings among people who know each other. For example, you would say 'Where's the bathroom?' to a host at a party, but 'I'm going to the john' to a close friend at a bar.

Etymology

English (from the personal name John)

The slang use of 'john' for a toilet is widely thought to come from Sir John Harington (1561–1612), an English courtier and godson of Queen Elizabeth I, who invented an early flush toilet called 'the Ajax.' Over time, the name 'John' became attached to toilet fixtures in popular speech. The use of 'john' for a sex worker's client comes from a different source: it draws on 'John' as a generic name for an ordinary man — similar to 'John Doe' — and was adopted into underworld slang in the early 20th century. Both meanings are informal and specific to English.
