Level base in two directions.
Note: Allow the bedding material to completely harden before applying
weight to the bottom of the shower base.
Place strainer back into place and conduct a water test of drain and
plumbing to ensure there are no leaks.

After the bedding material has been poured and before it sets,
lower the shower base into position with the drain assembly sliding
over the waste pipe (Fig. C). It will be necessary to "rock" the shower
base until the top of the tile flange aligns with the lines drawn on the
stud walls from Step 1. Make sure the apron is contacting the rough
floor along the entire length of the shower base and ensure that the
base is level in two directions as shown in Figure D.
Tape over the shower base drain strainer to protect the finish
and prevent construction debris from entering the drain. Finish
the shower base installation. Any finish material such as
shower wall tile or wallboard must be self-supporting if it
contacts the deck of the shower base as shown in Figure E.
Install the water resistant drywall while keeping approximately
1/4" (6mm) to 1/2" (13mm) of clearance between the shower
base and drywall to prevent any possible water from wicking.
