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.Many households have a microwave oven,a dishwasher and other electric appliances.The main function of a kitchen is serving as a location for storing,cooking and preparing food (and doing related tasks such as dishwashing),but it may also be used for dining,entertaining and laundry.

Commercial kitchens are found in restaurants,cafeterias,hotels,hospitals,educational and workplace facilities,army barracks,and similar establishments.These kitchens are generally larger and equipped with bigger and more heavy-duty equipment than a residential kitchen.For example,a large restaurant may have a huge walk-in refrigerator and a large commercial dishwasher machine.Commercial kitchens are generally (in developed countries) subject to public health laws.They are inspected periodically by public-health officials,and forced to close if they do not meet hygienic requirements mandated by law.
