Mix up some concrete mix in the mixer. Mark this outer height mark along the wall with a pencil. The pre slope is a slight slope of the floor draining toward the shower drain created with dry pack cement before the shower pan is installed. During the rough plumbing of the shower and tub the drain pipe ends were each encased in plastic boxes so when the slab was poured a void was created surrounding the end of each drain pipe.

Despite what you may think water can and will penetrate all the way through the tile mortar and concrete above the shower pan making its way down to the shower pan. The following five part series gives a basic overview of building a shower floor for tile. If the wall is 3 feet from the drain the cement should rise by 3 4 inches as it goes from the drain to the wall starting at the half inch depth around the drain for a total height of 1 1 4 inches at the wall. For example a floor that extends 4 feet away from the drain should have 1 inch of overall slope.

The mortar bed on top of the membrane is exactly the same thickness along the walls as it is at the drain. To determine the proper slope measure from the drain to each wall and figure a quarter inch of slope per foot of length. To efficiently drain the recommended minimum slope for a shower floor is about 4 percent or a 1 2 inch drop per every 12 inches from the shower walls to the drain. When tiling a shower one of the most important things to remember is that you need extra cuts in the tiles to make sure they follow the fall of the floor a.
