A kitchen sink mixer is a plumbing fixture that controls the flow and temperature of water in a kitchen sink. It combines hot and cold water streams to provide the desired water temperature for various kitchen tasks, such as washing dishes, rinsing fruits and vegetables, or filling pots and pans. A kitchen sink mixer typically consists of a single handle or lever that allows the user to control both the water flow and temperature by moving it from side to side or up and down. The mixer is connected to the hot and cold water supply lines, and by adjusting the handle or lever, the user can achieve their desired water temperature. Some kitchen sink mixers may also feature additional functionalities such as a pull-out spray head or a separate spout for filtered water.

 Kitchen sink mixers come in various designs, finishes, and styles to match different kitchen aesthetics and sink configurations. They are commonly deck-mounted or wall-mounted, depending on the design of the kitchen sink. Kitchen sink mixers provide convenience, versatility, and ease of use for a variety of kitchen tasks, making them an essential fixture in any kitchen.
