5.  Installation of Tub Leg Filler Panels (K)
A.  Tub Leg Filler panels (K) are installed from the oor to 
the bottom of the side walls next to the skirt of the tub, 
only when the side walls extend beyond the tub. First trim 
the height to t from oor to the bottom of the side wall 
panel. For a professional look, ller panel should match 
the contour of the tub. You can scribe the contour with a 
compass, or by hand, and cut with a jig saw or utility knife. 
Next, trim the outside edge to align with the outside edge 
of the side panel. Place a very ne bead of silicone along 
the top edge of the ller panel to seal it to the bottom 
edge of the side wall panel, then adhere ller panel as in 
Step 2.B.
NOTE: For alcoves that are only 1-2" larger front to back than the tub, 
the tub leg ller panels will not be needed, and the vertical trim molding 
(Item C or E) can be contour-cut to t right up against the tub.
6.  Installation of Back Wall Top Trim (G)
A.  Note the height of the shower head. Decide if top trims 
will be installed above or below shower head/escutcheon, 
keeping in mind that trims can overlap panels from ½" to 
2-1/2". Mark a level line at desired height of the top of the 
trim on the back wall (above the back wall panel).j
B.  Measure the distance from plumbing wall to opposite 
wall (sheetrock to sheetrock, NOT FlexStone to FlexStone). 
Cut item (G) to this measurement, then cut a notch ¼" wide 
in both ends. This will enable the trim to overlap the back 
panel and t over the end panels eliminating any large gaps 
or holes in the corners. 
C.  Dry t this trim piece and make sure it ts properly in a 
level position. Peel away protective masking from the trim, 
apply adhesive to the back of the trim molding, and adhere 
it over the back wall panel. Secure the trim piece in place 
while the adhesive cures using paint-safe masking tape.
NOTE: Trim moldings are shaped like an "L", and the long leg is 
designed to overlap panels, with the short leg returning back to 
the sheetrock and hiding the panel edge. Be sure to peel protective 
masking back from the edges of the panels before adhering the trim 
moldings.
