Installation Instructions
Gelcoat & Solid Surface Bathware
When the shower pan is removed from the packaging, use
a straight edge to check the straightness of the threshold.
Place a straight edge on the under side of the threshold
across the front to check the straightness. See Figure 2A
In the event it is not straight to 1/16”, pressure can be
applied to the top side of the material. This can be
accomplished by placing blocks under the two extreme
corners of approximately, 3” high.
Always place a soft rag on the nished surface where it
contacts the wood blocks, and under your feet to avoid
damaging the nish.
Gently step on this area and allow your body weight (Up
to 250 pounds), to ex the material back straight.
Conrm straightness, repeat if necessary until +/- 1/16” is
accomplished. See Figure 2B
6. Carefully measure the framing pocket to assure it is of
proper size for the unit to be installed. Refer to
dimensional information in the FRAMING DIAGRAMS-
Figure 1.
7. Check the framing pocket for square. Check to assure
the vertical studs are plumb. Check for square by holding a
measuring tape from the back left corner to the right front
corner, as shown in Figure 4. Repeat for the other side. If
both dimensions are the same, the framing is square. Adjust
if necessary.
These steps are necessary to assure a good installation of
the walls (provided by others) to be installed later.
8. The next step is to dry t the shower pan to the studs
and conrm the drain location.
The better t of the pan, the better all wall parts will
assemble as intended with minimal gaps at the seams.
Note in Figure 5 the two installers have placed the shower
pan on the oor, and are pushing it into the installed
position. One of the installers is using a short piece of 2 x
4 wood to hold the front of the shower pan off the oor.
This will assist in moving the pan into the installed position
while preventing chipping the front edge if it were to slide
along the sub oor.

Once the shower pan is put into place and
fit is confirmed, draw a pencil line on the sub floor
indicating the front point of the threshold of the pan.
(See Figure 8).
The back corners of the shower pan should be in
contact with the framing, as seen in Figure 7.
Shim these areas if required.
NOTE: There are 2 shower pans models that require
shims on the underside for installation. These models are:
When the shower pan is trial fit in the framing
pocket, shim under the leveling leg on the under
side of the pan. Place the shims and adjust
until the pan is level and does not rock.
These shims must be glued or screwed down in the
correct location before the final installation.
This step is required for these units to assure a correct
installation for these two higher threshold shower pans.
Place a piece of cardboard in the floor of the shower to
protect the floor during the additional steps of installation.
There is a cut out for this on the pan box.
After the pan is set, fill any gaps between the mounting
flange and the framing with wood shims or furring strips to
achieve solid contact. The flange must be in contact with
the studs along all sides.

The next step is to dry fit the shower pan to the studs
and confirm the drain location.
The better fit of the pan, the better all wall parts will
assemble as intended with minimal gaps at the seams.
