Installation Guide

Prepare the Site (cont.)
NOTICE: Adequate floor support is required. The wood support
must be a minimum of 2″ (51 mm) thick by 6″ (152 mm) wide. 2x6
lumber is NOT adequate for this application.
NOTE: Concrete can be used as the floor support.
Plan out the bath filler placement based on the dimensions above.
Cut a hole in the subfloor that is large enough to install the wood
support between two floor joists.
Secure a wood support 2-1/4″ (57 mm) by 3-1/16″ (78 mm) below
the height of the finished floor.
