A sink — also known by other names including sinker, washbowl, hand basin and wash basin—is a bowl -shaped plumbingfixture used for washing hands, dishwashing, and other purposes. Sinks 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. Many sinks, especially in kitchens, are installed adjacent to or inside a counter.
When a sink becomes clogged, a person will often resort to use a chemical drain cleaner or a plunger, though most professional plumbers will remove the clog with a drain auger (often called a " plumber 's snake").
