Bath tubs are made in sizes that vary in length from 4 1/2 to 6 feet. They are constructed in a variety of forms and of materials to suit all conditions of service. For domestic use they are very generally made of enameled iron. This form of construction produces serviceable and handsome furnishings for the bathrooms of the modest house as well as for the sumptuous bath of the most pretentious residence. An elaboration of Fig. 84 might include the Sitz bath shown in Fig. 85 and the fittings may be chosen from a great variety of forms. The recent styles of enameled tubs are, in design, much handsomer than those with the roll rim and in form such as permits a clean room with the minimum of labor. They are also provided with more convenient water and drainage fixtures.

The tub of Fig. 86 sets flat on the floor and makes a close joint with the wall. It thus prevents the accumulation of dust that is difficult to remove. In addition the fixtures are arranged in a more commodious manner and the general appearance is most pleasing. The arrangement of the fixtures in Fig. 87 gives still greater convenience and being arranged with a shower and protecting curtain, provides all of the conveniences of a luxurious bath without greatly increased cost over the simple tub. The fixtures in this design are all in position of greatest convenience and attached to pipes that are concealed in the wall. The fixtures usually provided with the tub are double Fuller or compression cocks for hot and cold water, the overflow and strainer, for the discharge of the water into the sewer in case the tub overflows, and a drain and bath plug.

The double Fuller cock is shown in Fig. 88. It is made to open and close by the same sort of mechanism as is shown in Fig. 71, a description of which appears on page 90.

The overflow is shown in detail in Fig. 89. The part A appears inside the tub. It is made water-tight around the edge C by a rubber washer that is clamped tight to the surfaces by the nut B. In case of leakage, the overflow may be removed for repair by unscrewing the union attached to the piece D and removing the nut B.

The part C is a union which permits the tub to be detached from the drain pipe. Repairs to this joint may be made as in the overflow.
