A toilet is a plumbing fixture primarily intended for the disposal of human excreta: urine and fecal matter. Additionally, vomit and menstrual waste are sometimes disposed of in toilets in some societies. The word toilet describes the fixture and, especially in British English, the room containing the fixture. In American English, the latter is euphemistically called a restroom or bathroom. The latter term often describes a room that also contains a bath tub. A room with only a toilet and a sink is sometimes called a half-bathroom, a half bath, or a powder room.
