In the United States, "bathroom" commonly means "a room containing a lavatory". In other countries this is usually called the "toilet" or alternatively "water closet" (WC), lavatory or "loo". The word "bathroom" is also used in the U.S. for a public toilet (the more formal U.S. term being "restroom"). In some U.S. markets, a toilet, sink, and shower are considered a "full bath".
