7. Cut Holes for Valves and Spout
For Units with Wall Surrounds Only
Holes for the valve handles and spout must be cut in the plumbing end wall. Refer to the manufacturer’s
instructions for the necessary hole sizes. Verify that any escutcheon, flange, or cover plate is large enough to
cover the hole for the component.
Lay out and mark the location of the mixing valve and shower on the back surface of the surround
wall.
Drill 1/4
″
(6 mm) pilot holes at the marked locations.
Clean the bath to reduce risk of surface damage.
Verify that there is a protective covering in the bath.
IMPORTANT!
If using a round hole saw or other rotary tool to cut the holes, cut the holes from the front
or finished side of the wall. If using a saber saw or other reciprocating saw with a blade that cuts on the
pull stroke, cut the holes from the rear of the wall. If using a hand-held jig saw or other saw that cuts on
the push stroke, cut the holes from the front of the wall.
Use a hole saw of the correct diameter to carefully drill the fitting holes.
Clean any debris from the bath to reduce the risk of surface damage. Be careful not to scratch the
surface of the product.
