A kitchen is a room or part of a room used for cooking and food preparation in a dwelling or in a commercial establishment. In the West, a modern residential kitchen is typically equipped with a stove, a sink with hot and cold running water, a refrigerator, counters and kitchen cabinets arranged according to a modular design. The main function of a kitchen is serving as a location for storing, cooking and preparing food, but it may also be used for dining, entertaining and laundry.
