Installation Sheet

For a finished appearance, install greenboard up to the front
edge of the shower base, leave a 1/2” gap between the shower
base and the greenboard.
In addition, if baseboard trim (not included) will later be
installed along the floor next to the shower base, a 1/2” gap
between the floor and bottom of the greenboard is
recommended (see illustration below).

4. Apply a coat of water or oil-based primer/sealer to all
the surfaces of the cementboard or greenboard (follow
the manufacturer’s instructions). Allow the primer to dry
thoroughly before installing the wall panels.
Panel Installation
Back Panel
If the back wall measures less than the width of the panel, cut
the panel to fit the opening (for alcove installation only).
1. Using a builder’s square, make sure the shower base
is perpendicular to the side walls. If the walls are out of
square, the bottom of all the panels may need to be cut to
follow the contour of the shower base.
2. If the shower base is not perpendicular to the wall, use
a level and draw a line around the alcove on all three
walls. Measure the distance from the line to the top of the
shower base.
3. Transfer these measurements to both side panels and the
back panel. Cut the bottoms of the panels.
Note: For any panels with tile patterns, this process will keep
the faux grout lines running level, although the bottom
tiles may not be evenly sized from the shower base to
the first faux grout line. Since every installation is slightly
different, it is up to the installer to create a pattern match
that is visually pleasing.
4. For alcove installation only: If the back panel must be
cut (side-to-side) to fit the opening, find and mark the
center of the back wall in the alcove opening. Use a level
to draw a line from the shower base to a point above the
height of the wall panel.

Installation Procedure
m Remove or reattach any loose ceramic tiles. Old tiles and
front edge ceramic tiles should be reset for appearance
only.
m Remove any tile accessories attached to the walls.
m Remove the bottom row of tile and cut a ventilation gap in
the substrate.
m Surface must be dry, smooth, and free of any dust, soap
scum, or any other contaminants.
m Complete the installation following the instructions in this
manual.
Wallpaper
m All wallpaper must be removed from the area being
covered. Clean the wall surface to remove any dust, soap
scum, or any other contaminants. The wall surface must be
dry and smooth.
m To ensure proper adhesion of the wall panels, the complete
wall surface must be sealed with two coats of water or oil-
based primer/sealer.
m After the primer/sealer is completely dry, complete the
installation following the instructions in this manual.
Masonite
m Clean the wall surface to remove any dust, soap scum, or
any other contaminants. The wall surface must be dry and
smooth.
m To ensure proper adhesion of the wall panels, the wall
surface must be sealed with a water or oil-based primer/
sealer.
m After the primer/sealer is completely dry, complete the
installation following the instructions in this manual.

Filler Boards
If an existing wall covering (i.e. tile) does not extend to a
height equal to the height of the panel, it will be necessary to
install a filler board to that height. The filler board must equal
the thickness of the existing wall covering (tile). Usually, 1/4”
masonite or similar material is adequate. If desired, the filler
board can extend from the top edge of the tile to the ceiling.

could result in water damage or other damage to floors, walls,
or other portions of your building or home.
Wallboard Installation
Note: If the wall panels will be installed over an existing
shower wall surface, proceed to the next section.
Install 1/2” moisture-resistant cementboard or greenboard
over back (1), front (2), and rear (3) wall surfaces of the rough
opening.
1. Measure and cut openings for the shower faucet(s) and
shower head before installation.
2. Install the wall board with a 1/2” gap above the shower
base side lip to prevent possible water (wicking affect)
damage.
