Installation Guide

Drain Location
Using the Shower Base and Drain Opening Rough-In
Dimensions chart, make sure the drain hole is properly
located. The recommended size of the hole in the floor
for the drain pipe is approximately 6” in diameter.
The drain of the shower base is designed for 2” cast-iron
(no-hub) or plastic drain pipes.
1. Dry fit the shower base to ensure a proper fit and
correct alignment of the shower drain and the hole in
the floor. The top of the drain pipe must be 1/4”
below the floor level.
2. Temporarily remove the shower base and proceed
with the installation instructions.
Standard Shower Base Installation
These instructions cover the installation of any square,
rectangular, or neo-angle shower base. Barrier free
shower floor and ramp installation instructions are
provided in a separate section in this manual.
The shower base is designed to be installed directly on
the subfloor and should rest loosely against the studs
maintaining the recommended minimum 3/16” gap.
For best installation results, it is suggested to install the
shower base using a mortar bed or equivalent material,
such as thinset.
1. Place up to a 1/2” thick layer of mortar/thinset on the
floor. This will ensure complete contact and support
by the existing subfloor, eliminating shower floor flex
during normal use. Taper the mortar/thinset to 1/4”
thick around the floor drain. Mix enough material to
cover the area under the shower base. Do not
place the material closer than 2” to the edge of the
shower base or the floor drain opening.
2. Place the shower base into the rough opening and
firmly press it into the mortar/thinset. Make sure the
side lips of the shower floor are parallel with the wall
with a gap (3/16” recommended) between the face
of the stud and the side lip.
Note: The mortar/thinset will prevent the shower base
from moving without the use of any mechanical
fasteners.
Do Not Use Nails
To prevent damage to the shower floor and
possible water or other damage to floors, pipes,
walls, or other portions of your building or
home, do not nail or screw through the shower floor to
secure it to the stud wall. Nails can be used, but are not
necessary, to hold the shower base in place. If nails are
used, they must be installed above the shower flange and
not through it. Refer to the specific instructions in this
manual for the proper installation of these optional nails.
