Toilets are bathroom fixtures used for the sanitary collection and disposal of human waste products such as urine and feces. Consisting of a bowl and seat, toilets provide hygienically safe and convenient facilities for relieving ourselves. Toilets come in a variety of disposal methods that range from common flush toilets, dry toilets, and vacuum toilets to pit latrines, portable toilets, and chemical toilets. Toilet bowls are typically made of ceramic (porcelain) but other disposal designs may be made from concrete, plastic or wood. Toilet manufacturers also offer diverse options for seat styles and bowl design along with new possibilities to integrate technology into the toilet that may improve your experiences. The most common toilet design variations are two-piece, one-piece, and wall-hung toilets.
