Freestanding kitchen and bar sinks, also called utility or scullery sinks, are usually made of stainless steel that's stain resistant and easy to maintain during food prep in commercial kitchens such as in school cafeterias, hospitals, and restaurants. These freestanding sinks are supported by four legs and include deep bowls for cleaning hands or dishwashing and rinsing glasses, dishes, or large pots. Drainboards are often included to prevent spills and provide a food preparation or dish drying surface.
