Countertop (also counter top, counter, benchtop, or (British English) worktop) usually refers to a horizontal worksurface in kitchens or other food preparation areas, bathrooms or lavatories, and workrooms in general. It is frequently installed upon and supported by cabinets. The surface is positioned at an ergonomic height for the user and the particular task for which it is designed. A countertop may be constructed of various materials, both natural and manmade, each with its particular attributes with respect to functionality, durability, and aesthetics and may incorporate or house appliances or accessory items relative to the intended application.
