FRONT

Insure the floor and stud walls 
are square and plumb. 
Provide a 5" x 5" (127mm x 
127mm) opening in the floor 
for the drain (see Figs. A & B). 
The drain plug accommodates 
a 2" (51mm) 

PVC

 waste pipe. 

The waste pipe should extend 
above the surface of the 
sub-floor 3/8" ± 1/16". 

Note:

 Variations in levelness 

of subfloor may require 
adjustment of waste pipe 
height. See product drawings 
on this page for the specified 
drain locations.

Before installing drain into 
the shower base, remove 
strainer (see Fig. C). This 
will be installed after 
shower base is in its final 
position. Install the drain to 
the shower base as shown 
in Fig. D. Use silicone 
sealant between drain 
body and shower base.
