[Illustration: FIG. 84.--Model bath room for the average dwelling.] Enameled iron has reached a state of perfection where it rivals porcelain in beauty. The forms of the various bathroom pieces have been modeled for convenience in use and grace of form, at the same time the strife of the designer has been to produce articles that not only look well but are convenient and easily kept clean. Bathrooms need not be expensive in order to be convenient, attractive and useful. The bathroom shown in Fig. 84 is such as is installed in dwellings of moderate price. It possesses every feature necessary to usefulness and comfort. In this room the furnishings are all of enameled iron. The floor is covered with linoleum and the wainscoting with enamel paint. =Bath Tubs.=--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. [Illustration: FIG. 85.--Sitz bath.] 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. [Illustration: FIG. 86.--Enameled iron bath tub.] [Illustration: FIG. 87.--Bath tub with shower.] 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.
