7. If a surface mounted accessory, such as a grab bar,
is going to be installed, make sure 2 x 6 wood
blocking is installed where the surface mounted
accessory will be attached. This will ensure a solid
backing for any mounting hardware.
Shower Base Installation
The shower base is designed to be installed directly on
the subfloor and should rest loosely against the studs
maintaining the minimum 3/16” gap. The drain is
designed for 2” cast-iron (no-hub) or plastic drain pipes.
For best installation results, it is suggested to install the
shower base using a mortar bed or equivalent material,
such as thinset.
1. Dry fit the shower base to ensure a proper fit and
correct alignment of the drain. The top of the drain
pipe must be 1/4” below the floor level.
2. Remove the base and place up to 1/2” thick layer of
mortar or 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 an
area approximately 1/2 x 24 x 42”. Do not place the
material closer than 2” to the edge of the shower
base or the floor drain opening.
3. Place the shower base into the rough opening and
firmly press it into the mortar/thinset. Make sure the
side lips of the shower base are parallel with the wall
with 3/16” gap between the face of the stud and the
side lip.
NOTE: The ideal placement of the shower base would
be 1/2” from the inside lip of the shower base to the face
of the stud. This dimension would allow the Swanstone
wall panels to rest against the lip of the shower base
once the moisture-resistant cement board is installed, as
shown.
