Roughing-In (cont.)
If installing this bath with a shower door, refer to the shower door manufacturer's instructions for any
special framing considerations.
1. Construct the Framing
Install the Framing
NOTE: Refer to the "Roughing-In" section for dimensions.
Install the subfloor if needed.
Construct 2x4 stud framing for your particular installation according to the "Roughing-In" section.
Ensure that the framing for each stud is plumb and square to within 1/8" (3 mm). Shim as needed
to meet tolerances.
Construct the Floor
IMPORTANT! Construct the floor of plywood. If the bath is installed over material other than plywood,
friction may cause squeaking over time.
IMPORTANT! Make sure the felt pad is properly positioned so that every bath-subfloor contact point has
felt between the bath and the subfloor.
Place the provided felt pad between the bath and the subfloor, positioned so that every
bath-subfloor contact point has felt between the bath and the subfloor.
Cut a hole in the floor for the drain.
Verify that the subfloor is flat and level. If the subfloor is not level, proceed to the "Level the Floor"
subsection.
IMPORTANT! Squeaking may develop if the bath is installed over a subfloor other than plywood. In
order to prevent squeaking place a pad between the bath and subfloor. The recommended pad material is
a spun bonded polyester landscape fabric, or spun bonded house wrap material. Do not use roofing felt
for this purpose.
Level the Floor (If Needed)
NOTE: Use cement or mortar for this application. Gypsum cement or drywall compound will not provide
adequate support.
NOTE: The bath supports must rest directly on a level subfloor.
Build a dam to keep the flooring material in the desired area. Be sure to dam the drain area.
Spread and level a layer of cement or mortar on the subfloor where the bath supports will rest.
Allow the cement or mortar material to cure.
Remove the dam.
Install the Ledger Strip
Cut three ledger strips from 2x4 lumber to fit the framing pocket. The rear ledger strip must be 60"
(152.4 cm) long. The end ledger strips must extend 39-3/4" (101 cm) from the rear ledger strip.
Adjust these dimensions accordingly if beveling the ends.
Install the ledger strips in the alcove no higher than 16-1/2" (41.9 cm) above the level floor. Ensure
that the ledger strip is level before fastening it into place.
NOTE: Nails must penetrate the framing studs to a minimum depth of 1" (2.5 cm).
Fasten the ledger strips using two nails per stud.
