Toilet (room)

A toilet, in this sense, is a small room used for privately accessing the sanitation fixture (toilet) for urination and defecation. Toilet rooms usually include a sink (basin) with soap for handwashing, as this is important for personal hygiene.

This room is commonly known as a "bathroom" in American English, a "loo" in British English, and by many other names across the English-speaking world.

"Toilet" originally referred to personal grooming and came by metonymy to be used for the personal rooms used for bathing, dressing, and so on. It was then euphemistically used for the similarly private rooms used for urination and defecation. By metonymy, it then came to refer directly to the fixtures in such rooms. At present, the word refers primarily to such fixtures and using "toilet" to refer to the room or activity ("use the toilet") is somewhat blunt and may be considered indiscreet. It is, however, a useful term since it is quickly understood by English-speakers across the world, whereas more polite terms vary by region.

"" (from the Latin lavatorium, "wash basin" or "washroom") was common in the 19th century and is still broadly understood, although it is taken as quite formal in American English, and more often refers to public toilets in Britain. The contraction "lav" is commonly used in British English.

In American English, the most common term for a private toilet is "bathroom", regardless of whether a bathtub or shower is present. In British English, "bathroom" is a common term but is typically reserved for private rooms primarily used for bathing; a room without a bathtub or shower is more often known as a "WC", an abbreviation for water closet, or "loo". Other terms are also used, some as part of a regional dialect.
