Systems of plumbing such as that shown in Plate 39 are to be found in Turkish-bath establishments, clubs, Y. M. C. A. buildings, and in other like institutions. Such a system usually includes a number of shower-bath compartments, other compartments for tub baths, swimming pool, lines of lavatories, and ample toilet arrangements.
A very important feature in the bath establishment is the liberal use of floor drains, for a great deal of water naturally falls upon the floors; and in addition, abundant opportunity must be provided for flushing and thoroughly cleansing. Owing to impurities washed from the skin, the bath rooms of an establishment of this kind may become exceedingly filthy unless constant attention is given them. For this reason many such bath rooms are supplied with flushing-rim floor drains provided with hot- and cold-water connections, which are very effectual in keeping such drains in a sanitary condition.
Plate XXXIX. Plumbing For Bath Establishment-Tanks For Storage And Supply
Plumbing for Bath Establishment Plate 39
All floors and walls of bath establishments should be of tile or waterproof material. The walls and ceilings should never be covered with any material that may absorb moisture and odors.
Generally the waste from a line of shower baths is carried off in a gutter at the rear of the stalls, the stall floors being graded so that all water will flow into the gutter.
The gutter may be formed in the floor itself or of slate or marble set into the floor for this purpose, or it may be of cast iron. The gutter should be graded to its outlet. The outlet should connect into a cast or wrought-iron waste line, and be provided with a trap, the size of which should be determined by the number of shower baths which are served, the size generally being from 2 to 4 in.
This trap should be provided with a 2-in. vent and cleanouts.
The plunge or swimming pool should waste through a 4-in. trap, provided with a 2-in. vent and cleanouts of the same size as the trap. The bottom of the pool should be graded toward the outlet end. The swimming pool should be provided with ladders reaching down into it, and a brass hand rail running completely around it.
The water of the swimming pool, when constantly in use, should be changed at least once in seven hours.
Although not seen in Plate 39, the swimming pool should be provided with an overflow. The plunge bath is now to be found occasionally in the basement of fine residences, and the use of shower apparatus of extensive nature has become a common feature of high-grade and well-appointed bath rooms. In some sections, where the water supply is not remarkably clear, the filtering of the water used in the bath establishment will be found to add much to its luxuries. As in the case of other public toilet rooms, it sometimes becomes necessary to provide a storage of water to be used at such times as the regular supply is inadequate.
Concerning the use of tanks, the following remarks may be of value:
