A sink (also sinker, hand basin, and washbasin) is a bowl-shaped plumbing fixture used for washing hands, for dishwashing 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.

Sinks are made of many different materials. These include:
 

•     Stainless steel
•     Enamel over steel or cast iron
•     Ceramic
•     Marble
•     Plastic
•     Soapstone
•     Concrete
