We recommend the use of 1/2" thick cement board as your shower backer. This is a common backer for stone
and tile. Using this backer will help comply with almost all city codes. A cement-based product like
WonderBoard or HardieBacker may also be used if it meets your local codes. Some codes require a vapor
barrier to be installed as well. We recommend a water/vapor barrier of 6 mil. plastic be installed before installing
the cement board. To do this, staple plastic so that it hangs 1" above the floor. Roofing nails may be used to
attach the cement board instead of screws, this prevents the plastic from wrapping around the screws.
IMPORTANT: Use your cement board as an indicator of squareness. The
cement board comes in square sheets. If you see gaps or areas where the
cement board is not fitting flush, fix the problem by removing the cement
board and shimming the board until it’s square and flush. If the seams of the
cement board are not flush and square, your wall panels will not be square
and flush.
1. Cut a notch in cement board to fit around threshold flange. Sanding or
shimming the 2 x 4’s at the top rim of the pan may be required to flush the
cement board. (dia. 5)
2. Place a bead of 100% RTV silicone on the front INSIDE face of the shower
pan flange. The bead should be in a zig-zag pattern. (dia. 5)
3. Place the cement board against the studs and rest it inside the shower
pan against the back flange. Attach the cement board to the studs with
screws or nails. DO NOT screw or nail into the metal shower pan flange.
4. Continue installing the remaining cement board.

nut and gaskets from the drain assembly.(dia. 3, previous page) Push the
drain collar #5 into the drain hole between the pan and the 2” pipe. With
the drain collar pushed flush to the pan surface, the 2” drain pipe should
not extend past the inside threads of the drain collar #5.
2. Make sure the pan and drain fit level to the floor.
3. Remove pan and apply 100% RTV Silicone to floor. (dia. 4)
4. Carefully lift the shower pan and set into place. Make sure the ABS pipe is
still centered.
5. Push and secure the rubber seal #4 onto the 2” ABS pipe.
6. Thread on the brass pressure ring #3 around the drain pipe with the
provided tool #2. Remove the tool after the brass pressure ring is installed.

the decorative trim plate and store in secure area until installation is complete,
