PLANNING YOUR INSTALLATION
Carefully remove the old bathtub at the installation site. The replacement showers are 82” tall so wall board should
be removed on all three walls to at least this height.
Study Framing Diagrams on Page 3 of this manual. Adjust drain and water supply locations if required.
Cutout in floor for drain requires a minimum size of 10” x 10”.
1.
3.
Modify framing if required. There should be a framing member behind each flange. Make sure your framing
is plumb and square.
4.
Planning is necessary for Thin-Set mortar to be placed in the drain core area for all installations. Proper blocking
is required to prevent the Thin-Set from flowing to the floor below.
5.
For installation of showers without Easy Base, wet Thin-Set mortar must be placed under the shower bottom to provide
structural support, and to maintain factory slope to the drain. See Figure 2.
INSTALLATION INSTRUCTIONS
1.
Always place cardboard or a drop cloth in the shower base to protect the finished surface. Working from the finished
side of the unit, using the proper size hole saw, cut holes for supply lines and shower head.
2.
Before you disassemble the shower unit, transfer the locations for the supply valve and shower head on the unit.
Mark these locations on the back (reinforced surface) of the unit. After double checking the locations, drill 1/4”
pilot holes.
Remove the connection bolts and disassemble the unit. If present, remove shower rod. Carefully carry the parts
to the installation area. Do not flex the parts when moving to avoid scratches and stress cracks.
3.
The shower parts may be caulked, reassembled and installed in one piece if there is sufficient room. Typically,
the parts are installed piece by piece starting with the base. If installing in one piece, the metal nuts and bolts must
be used for permanent connection. The installer must apply 100% silicone caulking to all connection surfaces for
final installation. If installing piece by piece, or as one piece, support under the unit must be provided as described
below. The support is necessary to assure factory slope to the drain is maintained.
4.
When installing piece by piece, use the plastic fasteners
in place of the nuts and bolts. The fasteners will act as
guides that will index the parts together for installation
where access to the back side in unavailable.
5.
Insert the plastic fasteners through the holes from
below so they point to the ceiling.
6.
Insert plastic fasteners through the holes in the vertical
mounting surfaces on each side of the back wall. These
must be inserted from the back so they point toward
the front of the shower. Again, apply 100% silicone caulk
to the fasteners before inserting them through the holes.
NOTE: The caulking must be allowed to cure before
assembly of the unit.
7.
Carefully position the shower base so it sits on the front mounting flanges. Install the drain fitting in accordance
with instructions provided with the fitting. Do not allow the base to sit on the drain fitting.
8.
9.
Apply a liberal amount of 100% silicone caulk to each
fastener before inserting them through the holes.
See Figure 1.
2
Study Framing Diagrams Figures 2 and 3 and note the important installation requirements.
Unless the shower is caulked and parts fastened together with nuts, washers and bolts as a one piece unit, the
shower base is installed separately from the wall sections. Before applying any Thin-Set or Adhesive, trial fit the
shower base to confirm the alcove is of proper size and the drain is located properly.
Make any adjustements at this time.
The shower unit must be disassembled for installation. All joints must be caulked as they are installed. When
moving the parts, take care to avoid striking the edges of the wall sections to prevent chips or cracks.
2.
Showers configured with the factory installed Easy Base
TM
self leveling, reinforced bottom will be installed using
panel adhesive. However, wet mud will be used in the drain core area on these units. See Figure 3.
For ALL installations, apply a heavy bead of polyurethane panel adhesive under the shower threshold.
