FRAMING DIAGRAM FOR BATHTUB REPLACEMENT SHOWER
Note that for ALL installations, Thin-Set mortar is used in the Drain Core area. Fill the drain core only 2/3rds full
of Thin-Set. Do not overfill as this will prevent proper floor draft and may push the drain area up causing the unit
not to drain properly. Make sure you block off the drain core to prevent the Thin-set from escaping to the floor
below.
Before beginning final installation, it is ESSENTIAL that the sub floor in the installation area be completely clean.
It must be free of all dirt, trash, oil, grease, water and other contaminants that may affect adhesion.
Thoughly clean the area before proceeding with the shower installation.
After blocking the drain core, apply the appropriate amount of Thin-Set in the drain core area. Then appy the
Thin-Set mortar to the installation area, as shown in Figure 2. Apply a wide bead of 3M polyurethane adhesive
(or equivelent) at the front where the shower threshold will be located.
Carefully lift the shower base into the framing alcove. Guide the shower drain pipe with a hammer handle or
equivelent. The entire bottom of the shower must be in contact with the Thin-Set mortar. The front threshold must
seat into the heavy bead on 3M adhesive.

When installing showers without the factory Easy Base, wet Thin-Set mortar must be appled to the sub-floor to
provide support of the shower base. The Thin-Set should be applied immediately before the shower base is set
in place. This Thin-Set should be thick enough to assure it will contact the bottom of the shower, but be plyable
enough so it may be dispalced as the shower is leveled.
Note that for ALL installations, 3M Polyurethane Adhesive (or equivelent) is use to adhere the shower threshold
to the sub-floor.
Apply a thick bead of 3M Polyurethane Adhesive (or equivelent) along the sub-floor where the shower threshold
will be located as illustrated in Figure 2.
After blocking the drain core, apply the apropriate amount of Thin-Set in the drain core area. Then appy the
adhesive to the installation area as shown in Figure 3. Use a notched trowel to spread the adhesive. Apply a wide
bead of 3M polyurethane adhesive (or equivelent) at the front where the shower threshold will be located.
Carefully lift the shower base into the framing alcove. Guide the shower drain pipe with a hammer handle or
equivelent. The entire bottom of the Easy Base including the threshold must be in full contact with the Construction
Adhesive.
