History of the Toilet

A toilet[n 1] is a piece of hardware used for the collection or disposal of human urineand feces. In other words: "Toilets are sanitation facilities at the user interface that allow the safe and convenient urination and defecation".[1] Toilets can be with or without flushing water (flush toilet or dry toilet). They can be set up for a sitting posture or for a squatting posture (squat toilet). Flush toilets are usually connected to a sewer system in urban areas and to septic tanks in less built-up areas. Dry toilets are connected to a pit, removable container, composting chamber, or other storage and treatment device. Toilets are commonly made of ceramic (porcelain), concrete, plastic, or wood.
