The sketches show clearly the methods employed to make a shower-bath waste and stall water-tight. The shower bath, as a separate fixture, is in use and the demand for it as a separate fixture is increasing rapidly. This demand comes from the owners of private houses. The plumber must therefore devise some way to make these connections tight and prevent any leak from showing in the room below. This fixture is so constructed that all waste pipes and trap come under the floor level with no way of getting to them from below. Therefore the piping for this fixture must be of a permanent nature. No pipe or trap made of material that is liable to give out in a short time should be allowed under a shower-bath fixture or stall. The two sketches, Figs. 82 and 83 illustrate two methods of connecting and making tight a shower stall. A plumber should always consider it his special duty to make his work complete and free from all objections. He should always prepare for any emergency that may occur in the future. This is rather a big task, yet the plumber when accepting all of his responsibilities has a big task. I state this to the beginner and emphasize the all-important fact that he must learn to perform and think deeply of the elements of plumbing to be able later on to handle successfully the problems that present themselves in the plumbing trade.

The heavy brass trap shown in the sketch has proved itself very satisfactory and can be made to fit almost any condition of piping or building construction. A flashing of sheet lead is soldered on the trap and carried out to the outside edge of the stall where it is turned up 1 inch, or to the floor level. When the flashing is carried out for only a foot on each side of the trap, the possibilities of a leak are greater.
