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 large enough to install the wood support
between two floor joists.
Secure the wood support between 2-3/8" (60 mm) to 3-3/16" (81 mm)
below the top of the finished floor.
