-Systems' recommendations for simple and reliable installation.
Determine desired location and trace around
the outside of the KERDI-BOARD-SN flange,
making sure the lines are level and plumb.
Cut and remove the wallboard such that the
niche will be supported on both sides by the
studs or other wall framing.
1
Insert the niche and fasten to the studs using
wood or metal screws, placing the fasteners
approximately 1/4" (6 mm) from the edges
of the niche. Fasten all corners and limit
fastener spacing to 12" (30 cm) o.c.
2
Apply the KERDI membrane over the wall
surface as described on page 22. Once
the membrane is solidly embedded, cut the
membrane to match the niche opening.

, or unmodified thin-set mortar and solidly embed it in the niche,
resting on the previously installed tile. The shelf may be raised at the back to create a slope, or the tile may be set on a slope, to prevent water from pooling
in the finished application.
