The design I give as a suggestion, to be modified and adapted to any style of design. The building could be connected to the house by a corridor, or by a glazed _xystos_, either abutting on to the main wall of house or a little detached. Off the lobby to the frigidarium are recesses for boots and for linen. The frigidarium--about 15 ft. square--has benches fitted up like one side of a divan, bay windows with space for plants and flowers, lavatory and toilet-table, and an ornamental fountain. A lobby separates this apartment from the bath rooms, and off it are a w.c. and a towel closet, which latter could be supplied with hot air. The combined lavatorium and tepidarium--14 ft. square--is a domed chamber, with semicircular recesses containing the plunge bath and lavatrina. A shampooing bench is shown. A marble dado surrounds the walls, and marble corbels are provided to pendentives of dome--which could be of brick or terracotta and concrete--and marble springers to horse-shoe arches. The shower is placed over the lavatrina. Plenty of space is left for a bench or chair in this chamber. Adjoining is the laconicum with a firebrick furnace, after the nature of that of which I have before given full detailed drawings. The vitiated air is drawn through flues in the floor, to a shaft on the opposite side to the chimney. The stokery and coke-store adjoin the laconicum. Fresh air would be admitted to the furnace as explained in the detailed description of the furnace illustrated at Fig. 10. If there were no available supply of water from house, a boiler and tank could be placed in the stokery, and a cistern on the flat roof. The flat roof, if of iron and concrete, would form an abutment to dome. If thought desirable, the same flat roof could be carried over the combined tepidarium and lavatorium. An air space should be left between the masonry of dome and covering of copper or other material. The lights should be double glazed. With the radiating stove there is no objection to the loftiness of the dome. This bath could be perfectly ventilated and supplied with pure heat of a most hygienic character. CHAPTER IX.
