Stoneware makes the best kind of laundry tub from every point of view, and they are almost as cheap as enameled iron tubs. The stoneware is non-absorbent. It is very smooth, and will not crack by the variations of heat and cold. This style of laundry tub should be set on a solid foundation of either brick piers or good strong cast iron legs; there should be no woodwork around it, and even a wooden cover is very bad on a laundry tub. Some persons cover over the laundry tub for the purpose of making it answer as an ironing board, but it is not intended for this purpose. To close up the top of the laundry tubs prevents the air from circulating through them, and what little particles of soap or other matter that remain even after cleaning the tubs soon form into a gas which makes a very unpleasant smell when the cover is raised.

A stoneware laundry tub with metal rim, brass plugs, strainers, overflow and waste connections is shown in Fig. 161.

A somewhat similar stoneware laundry tub is shown in Fig. 162, only without the metal rim on the edges of the tub. It has a high back and the faucets are above the level of the tub proper.

The proper sanitary plumbing connections for a laundry tub are shown in Fig. 163. The waste pipes from the tubs and the connection from the trap to the main waste are 1 inches diameter;
