A sink (also sinker, hand basin and wash basin) is a bowl-shaped plumbing fixture used for washing hands, for dish washing or other purposes. Sinks generally have taps (faucets) that supply hot and cold water and may include a spray feature to be used for faster rinsing.
 They also include a drain to remove used water; this drain may itself include a strainer and/or shut-off device and an overflow-prevention device. Sinks may also have an integrated soap dispenser.
