Mix a non-shrinking bedding material such as mortar and apply enough bedding material to support the entire bottom
of the shower base.
Concrete is NOT recommended. The shower base is NOT to be supported by the base flange.
Tape over the strainer to protect the finish and prevent construction debris from entering the drain.

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
.
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.
