Usage notes

From the beginning of the 20th century, bathroom has been the generic word for a room with toilet facilities in American English. As Britons continue to say lavatory relatively more frequently and often loo or WC for a room with a toilet but no bath. Partly from French influence, such rooms are also relatively more common in British homes.[citation needed]

In some contexts, bathroom refers more particularly to the toilet facilities of a private residence, distinguished from public buildings' restrooms, men's rooms, ladies' rooms, etc.
