7 INSTALLATION OF SIDE WALL TRIMS (C, D, E, F).
Note: Vertical trim moldings are designed to be installed either: 1)
resting on top of the shower base threshold, or 2) outside the
threshold and running down to the floor. Depending on the size of
your alcove opening, you may even choose to contour cut the trim
moldings to overlap the threshold partially.
7.1) Place horizontal left wall top mitered trim (Item D)
in place, push into the corner against back wall
trim piece, then level it. Mark a level line on the
wall on the top side of the molding near the outer
end. Set aside this trim piece.
7.2) Measure from the floor to the level mark made in
7.1 to determine the length needed for the vertical
trim piece (Item C). Cut vertical trim piece (C) to
this length, but do not cut from the pre-mitered
end!
7.3) Fit vertical trim piece (C) over panel and plumb
using a level. If contour cutting this molding to
match the shower base shape, do so now. You can
scribe the contour with a compass, or by hand,
and cut with a jig saw or utility knife. For tub
installations, the back side of the molding will not
be supported by panel material in the contour cut
region outside the tub. Use a piece of cutoff scrap
as a filler behind this area of the molding. Peel
away protective masking from the trim, apply
adhesive and adhere molding to panel. Secure
with masking tape as in Step 6.3.
7.4) Measure horizontal distance from back wall
molding piece to the tip of miter on the vertical
molding. Cut horizontal top trim molding (Item D)
to this dimension by cutting off the end opposite
the miter. Be sure not to cut the mitered end.
7.5) Dry fit the molding (D) in place for a tight fit. Peel
away protective masking from the trim, apply
adhesive on the backside of the molding and
adhere to the wall as before. Make any minor
adjustments necessary to ensure that the mitered
end makes a tight joint.
7.6) Repeat 7.1-7.5 for the opposite wall trims (E, F).
