Under mud shower pan

The method of installing tile on a prefabricated shower pan, the method comprising the steps of:

• (a) inserting a conventional drain pipe into a drain hole of a one-piece pre-fabricated shower pan and fastening the conventional drain pipe to the shower pan using flanges so that the conventional drain pipe extends above the surface of the bottom of the shower pan between ½ to 2 inches;
• (b) floating cement or other adhesive on the interior surface of a shower pan in sufficient amounts such that when tile is placed over the cement or other adhesive, the top surface of the tiles are substantially flush with the top portion of the conventional drain pipe;
• (c) inserting a wall system inside the shower pan, wherein the shower pan has side walls against which the wall system is pressed, the wall system is wrapped in butyl tape to ensure a strong bond and create a water proof barrier to prevent water migration up the wall system, cement or other adhesive is floated against the interior surface of the wall system wrapped in butyl tape, and tile is placed over the cement or other adhesive;
• and
• (d) floating cement or other adhesive over a waterdam and over a fin of the waterdam, and placing tile over the cement or other adhesive, the amount of cement or other adhesive and the thickness of the tile dictating the elevation of the waterdam.
