Installation Instructions

3. Locate the Drain Pipe and Shower Receptor
Locate the Drain Pipe
NOTE: The drain system is designed for a 2″ (5.1 cm) drain pipe that is flush with the subfloor.
Determine the location of the drain pipe using the dimensions illustrated.
Cuta5″ (12.7 cm) to 5-1/2″ (14 cm) hole in the subfloor. This will provide adequate clearance for
the drain system.
Install the drain pipe. Verify the drain pipe is self-supporting and strapped down.
Locate the Shower Receptor
NOTE: The subfloor under the shower receptor must be level. Adjust the subfloor with leveling compound
as needed. Do not shim.
Place the shower receptor firmly against the two adjacent walls. Ensure the drain pipe is aligned
with the precut hole in the shower receptor.
Verify the shower receptor is flush against the studs.
If the shower receptor is not flush against the studs, use shims between the nailing flange and stud
wall as needed.
