In order that some one will be on the premises at all times to give the building personal attention, living-rooms are provided for the superintendents of public bath houses, usually on the top floor, and these living-rooms require all of the sanitary appliances of a like apartment in any other building. In the bath house proper the requirements will depend to a great extent on the completeness of the equipment. For instance, but few baths are provided with a hot-air room, or "sweat room," such as is used in a Turkish bath, yet no more beneficial provision could be made, for the "sweat bath" is the most cleansing to the skin and purifying to the blood of all the baths. As the installation of a "sweat room" is a very simple matter and not at all costly, it would seem that no public bath should be erected without this important adjunct. From the hot-air room the bather could pass to a shower bath for a good scrubbing and subsequent cold spray to close the pores and tone the system. Next to the hot-air bath and the vapor bath the ordinary bath tub is the most beneficial, but outside of some bath rooms in the women's apartments tubs are not so desirable as shower baths. Soap and dirt cling to the surface of bath tubs and would have to be cleaned away after each bath. Liability exists of spreading disease if the tubs are not properly cleansed, and, finally, more time would be required for each bather if tubs were used, without giving them the advantage of a cold shower to finish off with. For these reasons overhead shower nozzles are commonly provided for general use in public baths, and bath tubs provided only in a few of the compartments in the women's departments, where they may be used by women either for themselves or for bathing children.
In addition to bathing-facilities, toilet accommodations must be provided both for men and women, and instead of having separate days when the bath house is for the exclusive use of men or women, it is much better to have separate compartments where either can bathe at any time.
In the larger and more complete bath houses plunge baths are constructed, and while they add greatly to the attractiveness of the place, and tempt many people to the establishment during the summer months, still they are not of much value from a bathing standpoint, as they are very poor cleansers of the person. As between the plunge bath and the hot room, the latter is by far the more preferable where real value instead of attractiveness is desired. Swimming-baths, on the other hand, do untold good by alluring people to the bath house who otherwise would not attend, thus making of them regular patrons.
In order to launder numerous towels, sheets and bathing-trunks, unavoidably soiled in a bath house, a laundry is indispensable, and this may well be located in the basement. Rotary machine washers, centrifugal water extractors, drying-racks and mangles, all run by power, are about all that will be required even in the largest establishments.
