Board toilet

Board toilet of an aircraft (Airbus)

Board toilets are built-in rooms in vehicles, equipped with a toilet, for the use of human excretion.

The small rooms also often are equipped with at least a sink, liquid soap and paper towels for hand washing. Except in luxury versions, toilets of this kind are usually small and uncomfortable.

The feces are put in a basin (chemical toilets except on aircraft where a holding tank is utilized) or, on some ships, piped overboard. They are found in large aircraft, ships including manned spacecraft, some road vehicles (recreational vehicles, coaches) and many passenger train cars.
