3. Prepare the Receptor and Subfloor
CAUTION: Risk of property damage. The seal on the drain must be made watertight, or the subfloor
may sustain water damage.
Install the drain fitting to the shower receptor according to the drain manufacturer's instructions.
IMPORTANT! Construct the floor of plywood. If the shower or receptor is installed over material other
than plywood, friction may cause squeaking over time.
If the subfloor is constructed of a material other than plywood, position the supplied felt pad under
the supports.
Move the receptor into the installation location.
Verify that the receptor is level and well supported by the floor. If required, remove the receptor and
place shims under the receptor feet to level the receptor.
When the receptor is leveled, an optional mortar bed may be used to help secure the unit.
Install a Mortar Bed (Optional)
Remove the receptor from the alcove.
Remove the felt pad, if present.
NOTE: The receptor supports must rest directly on the subfloor.
Build a dam to keep the flooring material clear of the drain area.
NOTE: Do not use gypsum cement or drywall compound for this application, as they will not provide
adequate support. Use mortar.
NOTE: Do not spread mortar around the receptor feet.
Spread a 2" (5.1 cm) layer of mortar on the subfloor.
Remove the dam.
Move the receptor into position.
Verify that the receptor is level and resting on all supports.
Position a clean drop cloth or other similar material into the bottom and over the outside edge of
the receptor. Be careful not to scratch the surface of the receptor.
