A squat toilet (or squatting toilet) is a toilet used by squatting, rather than sitting. This means that the posture for defecation and for female urination is to place one foot on each side of the toilet drain or hole and to squat over it. There are several types of squat toilets, but they all consist essentially of a toilet pan or bowl at floor level. Such a toilet pan is also called a "squatting pan". A squat toilet may use a water seal and therefore be a flush toilet, or it can be without a water seal and therefore be a dry toilet. The term "squat" refers only to the expected defecation posture and not any other aspects of toilet technology, such as whether it is water flushed or not. Squat toilets are used all over the world, but are particularly common in some Asian and African nations, as well as in some Muslim countries. In many of those countries, anal cleansing with water is also the cultural norm and easier to perform than with toilets used in a sitting position. They are also occasionally found in some European and South American countries. Squat toilets are regarded as traditional by many. In 1976, squatting toilets were said to be used by the majority of the world's population. However, there is a general trend in many countries to move from squatting toilets to sitting toilets (particularly in urban areas) as the latter are often regarded as more modern. Squat toilets are arranged at floor level, which requires the individual to squat with bent knees. In contrast to a pedestal or a sitting toilet, the opening of the drain pipe is located at the ground level. Squatting slabs can be made of porcelain (ceramic), stainless steel, fibreglass, or in the case of low-cost versions in developing countries, with concrete, ferrocement, plastic, or wood covered with linoleum. Slabs can also be made of wood (timber), but need to be treated with preservatives, such as paint or linoleum, to prevent rotting and to enable thorough cleaning of the squatting slab.
