Step 3
Mix a modied thin-set mortar suitable for the suboor as per
manufacturer specication. Use a 3/8” square notched trowel and
apply thin-set mortar to the oor and backside of shower pan. Assure
that the thin-set is troweled in the same direction. Spreading the
thin-set with a square notched trowel will assure full coverage. Set the
shower pan in place.
Step 1
Cut the PVC pipe down to 2” below suboor by using a internal
PVC pipe cutter drill bit. Use a 2” rubber gasket to connect to
the 2” waste pipe and to the Dural adapter.
Step 4
Protect the shower pan by using a double layer of cardboard. Take two
bags of thin-set and place them in the drain area for extra weight to assure
the pan slope stays at a minimum of 2%. The drain cover will be screwed
onto the pan just before tile installation.
Suboor Prep
You must begin with a dry and structurally sound suboor. If water damage, rotting, or any other
structural defects are present, you MUST repair prior to installing your new showerboard. A clean
and level suboor is required for a successful installation. After cleaning the suboor, use a level to
check the suboor. The suboor MUST be level so that the showerboard will drain correctly.
Note: a self-leveling mortar can be used to level the suboor.
Step 2
Pret the shower pan and cut to t the shower
area, if needed. You can cut the foam board with
a utility knife or a circular saw. If the hole in the
suboor is wider than 4” diameter, use the metal
plate to support the area around the PVC pipe.
Install the Dural adapter to the rubber gasket. The
adapter has to sit 1/4” above the level suboor.
