Laundry tubs, generally speaking, are made of slate, cement, soapstone, glazed earthenware, or solid porcelain. Wood, cast iron or sheet steel are not suitable materials for wash tubs. Tubs used in tenement and apartment houses should be provided with overflows. The height of wash tubs from floor to top of rim is from 32 to 36 in. The wringer should be set on the right-hand tub.

The following tables give the average sizes of slate and cement tubs:
