How to Construct a Tile Shower Pan
- 1). Set cement board on the floor of your shower stall frame. Cut the board with a jig saw to fit. Cut a hole at the center for the drain. Glue down the board with carpenter's glue, and sink galvanized screws every six or eight inches.
- 2). Position the drain in the hole. There should be an adjustable rim that sits loosely around the outside of it, on the cement board.
- 3). Lay concrete mesh over the floor, covering everything except the drain. Attach the mesh with a staple gun.
- 4). Mix Portland cement, following the packaging instructions. Pour it over the cement mesh. Make it about 1/2 inch thick around the drain, then slope it upward toward the walls with your cement trowel at an angle of 1/4 inch per foot. For example, if the walls are all three feet from the edge of the drain, the cement should be 1-1/4 inch deep at the walls (because it started at 1/2 inch by the drain, and rose by 3/4 inches over a 3-foot span).
- 5). Let the cement set. Spread plastic floor liner over it, using a razor knife to cut out the hole for the drain. Put liner glue under the edge of the liner where it skirts the drain. Attach the liner to the walls with a staple gun, letting it rise about a foot from the floor.
- 6). Put a second layer of cement over the liner. Make it 1 inch deep, keeping the same slope that you started with.
- 7). Set the drain flange into the cement. Let the cement cure for two or three days. The shower pan is now ready for tiling.
