A kitchen is a room used for cooking, food preparation, and related tasks. Modern residential kitchens typically include appliances like a stove, sink, refrigerator, and cabinets. Commercial kitchens found in restaurants and other establishments tend to be larger with heavier-duty equipment and are subject to public health regulations. Kitchens in schools for teaching cooking skills have multiple workstations with individual ovens and equipment. Proper kitchen design with well-planned cabinets and appliances can create an efficient workspace.
