In the tub which is built into the wall, there is a tendency to neglect proper piping conditions. When installing a solid tub, it is necessary to build a bulkhead in back of the tub so as to take care of the waste pipe which should be available to the plumber as it often needs a new washer. Or it must be built against a closet wall so that the pipes are easy to get at, or against a hall wall or some stable place. VALVES There are myriads of styles of faucets, vents and outlets used to-day in tubs. It was at first thought advisable to have the inlet as near the floor of the tub as possible in order to make the pour of the water practically soundless after the first inch or two came in. This is about the only advantage of this arrangement. It is far better to have the inlet higher up, either on top of the wall of the tub, or even in the wall above the tub. If it is in the wall of the room it is impossible to hit your back while bathing; and you may have a shampoo nozzle attached; or draw water from it whether you are in the tub or not, and when necessary, fill a pail or dish. There is more noise when the water is running into the tub, but what of it? If you have a good door on your room, that will silence the sound. With the low inlet, there is a remote danger of drawing in through the pipe dirty water from the apartment above if some one is bathing in the tub which is a twin to yours. It is quite possible for this to happen unless the plumbing system is very well contrived. You can have a hot water and a cold water faucet or one faucet from which both hot and cold come. This is a matter of taste. More often there are two, but many people like one, so that there can be a mixture of water, giving a comfortable temperature. Tubs, of necessity, have to be placed in many ways. When in recesses or in a corner, the valves, etc. can be placed at one end. When against a wall, the piping can be placed above the bath in the wall. This method often lends a luxurious air to a room and has been utilized in the most elaborate ones. THE SHOWER BATH Nearly every modern bath has a shower of some description. The difficulty with the shower is the splashiness of it. The first protective device was a cloth on a bracket. This is still used to a great extent, but the ideal arrangement is to have the shower in a closet designed for it, opening into the room. This closet may be of glass, marble, or tile, with a cloth curtain or a door to match the material of which the section is built. The door should be as small as possible. Twenty inches is quite large enough. The smaller the opening, the less chance for the escape of water. Besides, a large door is a nuisance to clean.
