A sink—also known by other names including sinker, washbowl, hand basin and wash basin— is a bowl-shaped plumbing fixture used for washing hands, dishwashing, and other purposes.

Stone Sink China have taps (faucets) that supply hot and cold water and may include a spray feature to be used for faster rinsing. The wash-stand was a bathroom sink made in the China  in the late 18th century.

The washstands were small tables on which were placed a pitcher and a deep bowl, following the English tradition. Sometimes the table had a hole where the large bowl rested, which led to the making of dry sinks. From about 1820 to 1900 the dry sink evolved by the addition of a wooden cabinet with a trough built on the top, lined with zinc or lead. Self-rimming (top-mount) sinks sit in appropriately shaped holes roughly cut in the countertop (or substrate material) using a jigsaw or other cutter appropriate to the material at hand and are suspended by their rim.

The rim then inherently forms a fairly close seal with the top surface of the countertop, especially when the sink is clamped into the hole from below. Solid-surface plastic materials allow sinks to be made of the same plastic material as the countertop. These sinks can then easily be glued to the underside of the countertop material and the joint sanded flat, creating the usual invisible joint and completely eliminating any dirt-catching seam between the sink and the countertop.
