Steps:
1. Measure opening and transfer those measurements to the cement board. Use a square to be sure you make a straight line. Make six to eight scribes along the line with a utility knife, and then snap off the excess.
2. Set the board in place and secure it with cement-board screws.3. Find center on the wall and use a level to extend the reference line. Mark for the height of the diverter, and use the provided template to trace for the cutout. Make a pilot hole with a 1/2-inch drill bit, then cut the opening with a jigsaw.
4. Attach the copper stubs to the diverter before fastening it to the wall. Flux the fittings, then solder them together. Put Teflon tape and paste on the diverter, and screw on the supply stubs. Attach the diverter to a backer board with copper brackets.
5. The no-caulk drain assembly screws right onto the sink. Tighten it with locking pliers.
6. Use a jigsaw to cut the opening in the subfloor for the drain. Set two 2x4s on the ground to set the sink on so you don't pinch your fingers. Slide the sink into place, and remove the boards.
