It may be found convenient to arrange the valves for the whole of the above-mentioned appliances together, as at Fig. 16. Each pair of hot and cold handles are here brought together. These handles should be long, so as to admit of easy regulating of the temperature of the water; they may well be 9 in. in length. The douche, wave, and spray should be kept as close as possible to the handles that regulate their temperature.
I would repeat the caution that it is very necessary to beware of complications in these water-fittings and appliances. Some of the more "fussy" contrivances—as, for example, the elaborated needle bath as above described—require so much regulating, and so many valves and stop-cocks, that it is quite an undertaking for the attendant to set them going. Simplicity in design and construction should be observed in this work: the pipes as few as need be; the valves as simple as possible; and the whole put together in a manner that will permit of their being easily examined and repaired.
I have before hinted at the desirability of making some sort of provision whereby the bather may, on entering the bath, have a warm spray or shower, of any temperature that may be agreeable to him. In high class baths this feature should always be provided, as it is a great luxury, and, moreover, to certain constitutions a necessity, thus to be able to take such a shower before entering the hot rooms, or at such intervals during the sojourn in these apartments as may be desired. The proper position for this shower-bath requires some consideration. Were it only for the entering bather that it should be provided, it would be best placed in a lobby near the entrance to the hot rooms; but as the occupants of the hot rooms may frequently desire some such shower, it must be arranged with regard to this fact. It should be convenient for the entering bathers and for those in the bath. A small chamber entered by doors from the lobby to the tepidarium, and also from the tepidarium itself, would be convenient. At times it may be placed in a nook off the shampooing room. Wherever it be placed, the apparatus provided for the purpose of the shower must be such as can be managed by the bather himself, so as not to take up the time of the attendants; and for this reason it must be capable of easy regulation, and free from liability of scalding the user, unless through gross carelessness. A valve with one handle only must be employed, as, unless the bather has had some practice, it is difficult to obtain this immunity from danger of scalding when two handles are used. A valve such as that shown at Fig. 17 should be employed. This valve must be so designed as to supply cold, tepid, and hot water in regular gradation—not intermittently, as do some valves of this description. It must be so placed that any one taking the shower may, whilst beneath the rose, be able to easily reach the handle. The rose should not be less than 6 in. or 7 in. diameter. Fig. 12 illustrates the complete fitting up of this bather's shower-bath.
In hydropathic establishments it might be an improvement to add a small foot-bath, formed by a sinking of about 6 in. in the floor, and filled with hot water; for physiologists tell us it is bad for invalids to enter the hot rooms with cold feet. Supply pipes, a waste, and overflow would have to be provided for this bath, and a marble seat might be placed round it. A marble coping and mosaic flooring would render it pleasing in appearance.

Bather's Shower Bath.
I have hereinbefore, at Fig. 4, given plan and sections of a plunge bath, and shown its water-fittings. The overflow and waste run into cast-iron drainpipes, which should be employed till outside the building. On the end of the overflow pipe is screwed a gunmetal rose with leather packing, the screw-holes being drilled into the flange of pipe. For the waste I have shown a "disc" valve of gunmetal. This is similarly screwed to flange of pipe, and with leather packing. The valve is opened and closed by a movable rod. If fixed, it might catch the toes of the swimmer, and for this reason it would perhaps be best to set the valve itself back in a recess. Instead of this valve, an ordinary 4-in., 5-in., or 6-in. "plug" waste could be employed, but it is rather clumsy on such a scale. When practicable, a screw-down valve, with wheel and spindle outside the bath, is the best means of letting out the waste water. The supply-pipe should be connected with the main supply just after the water meter. The valve should be of the "screw-down" pattern, either with a thumbscrew, wheel and spindle, or a key.
In coast towns, where a sea-water plunge may be employed, a little rose on a bracket should be provided in a convenient position, for cleansing the hair from salt water.
Of the lavatory fittings in the cooling room, and of the "sanitary" water-fittings, it is unnecessary to speak, except to say that, in a place devoted to the attainment of cleanliness, plumbing of this nature should be as perfect as possible.
A drinking fountain is a desirable feature in the tepidarium of a bath of any pretension. It should be placed at the coolest end of the room, affixed to a wall, and provided with a supply-pipe, waste, and tap of some sort. The bowl is best formed of glazed earthenware.
