6. Seal the Module Sections
Clean the shower module to reduce the risk of surface damage.
Place a clean drop cloth or other similar material into the bottom of the module.
Wear gloves and use a soft damp cloth to carefully wipe the joining surfaces of each module section
and remove any dust or dirt.
Apply a 2" (5cm) wide strip of masking tape along the entire length of the joining surfaces on the
inside of each module section.
Insert a flat washer between the upper and lower mounting blocks at each door column and the
back corners to create a gap for the sealant. Make sure the washers do not block the bolt holes or
protrude into the wall joint. The bolts should be able to be inserted into the mounting blocks
without passing through the washers. Do not install the bolts at this time.
NOTE: Use of clear silicone sealant is recommended to ensure against leakage. Use of acrylic or other
caulks is not recommended.
NOTE: Sealant may set quickly. Proceed to the next steps immediately.
Work from the inside of the module and apply a generous, continuous bead of silicone sealant into
the joint.
Reinstall the bolts into the upper blocks and gently tap them into the corresponding lower blocks.
Remove the spacer washers and allow the upper section to slide down.
Tighten all the bolts starting at the door columns and work to the center of the back wall. See
illustration for tightening sequence. Do not overtighten.
Immediately wipe away any excess sealant from the front face of the module.
Spread out any excess sealant found along the backside seam areas.
Apply additional sealant to the backside seams.
Verify that all nuts and bolts are tight.
7. Prepare the Module
CAUTION: Risk of property damage. If a watertight seal on the drain is not obtained, water damage
to the subfloor may occur.
Install the drain to the module according to the drain manufacturer's instructions.
Layout and mark the location of the mixing valve, shower, and the bath spout holes on the back
surface of the module wall.
