A toilet is a plumbing fixture and disposal system primarily intended for the disposal of the bodily wastes: urine and fecal matter. Additionally, vomit and menstrual waste is sometimes disposed in toilets in western societies. The word "toilet" can be used to refer to the fixture itself or to the room containing the fixture, especially in British English. In Canadian English, the latter is euphemistically called a washroom, and in American English, a restroom or bathroom. The latter term usually refers to a room that also contains a bath tub. A room with only a toilet and a sink is sometimes called a half-bathroom or a powder room.
There are two basic types of toilets: the dry toilet, and the wet toilet - the latter being the most commonly known and producer of blackwater. The dry toilet needs no plumbing for water input or evacuation, but is often coupled with some ventilation system.
The ancient cities of the Indus Valley Civilization, e.g., Harappa[1] and Mohenjo-daro[2] which are located in present day India & Pakistan had flush toilets attached to a sophisticated sewage system[3]—and other forms of toilets were used both in the time of the Romans and Egyptians as well.[4] Although a precursor to the modern flush toilet system was designed in 1596 by John Harington,[5] the toilet did not enter into widespread use until the late nineteenth century, when it was adopted in English upper class residences.
The most common type of toilet in modern cities is the flush toilet, in which water takes away the waste through sewers to a waste treatment plant. In rural areas where sewers are not practical, septic tanks may be installed instead.
The most common design in western countries is the sitting toilet. Squat toilets are still used by the majority of the world's population.[7]
