Abstract: A dual capacity sink has two basins divided by a divider which extends to a much lesser height than the peripheral walls of the sink. In one capacity the sink is capable of holding a volume of fluid, such as soap or rinse water, in one or both of the basins up to the top the divider. In this capacity, the basins can be used individually, for example, one to wash and one to rinse. In another capacity the sink is capable of holding a second volume of fluid using the two basins and also the available space in the sink above the divider. In this second capacity the sink effectively becomes a large single basin sink. There is sufficient fluid in the sink above the divider for submerging items that are larger than either of the basins individually. A method of washing items in such a sink is also disclosed.
