Base Installation

 Strip alcove to bare studs.
Shower stud pocket should be constructed 
as shown. 
Studs should be plumb and square to 
sub-floor.
Floor must be clean, smooth, and level - 
check with level. Sub-floor must be
installed in the stud layout. Do not install 
shower base on open floor joists. 
Cut hole in sub-floor as shown to 
accommodate drain (not included).
  Trial fit base in prepared alcove. 
With base sitting flat on floor, check with 
level on top of base. Base should be level 
from front-to-back and side-to-side (Fig 1).
If base is not level, install wood shims 
between base feet and sub-floor as needed.
Remove base from alcove.
Optional: If sub-floor is not level, a floor 
leveling compound (smooth mortar) or a 
similar quick-setting compound specifically 
made for leveling floors is an excellent way
to fully support and level base instead of 
wood shims.
  Apply construction adhesive to all feet 
and install base into alcove (Fig. 2).
Level base with shims into construction 
adhesive under feet (Fig 3).
After base is leveled, if alcove is larger than 
base, shim between base and studs
to create tight fit. Predrill hole using 1/8” 
drill bit. Then screw base flange to all studs 
(Fig 4).
NOTE: Failure to screw flange to all studs 
will void warranty.
