Countertop (also counter top, counter, benchtop, (British English) worktop, or (Australian English) kitchen bench) 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 with different attributes of functionality, durability, and aesthetics. The countertop may have built-in applicances, or accessory items relative to the intended application. In Australian English, the term counter is generally reserved for a surface of this type that forms a boundary between a space for public use and a space for workers to carry out service tasks. In other contexts, the term bench or benchtop is used.
