Using a utility knife cut the cardboard along the scribe line.

Attach countertop to half wall.

If the holes are not completely lining up or you want a more secure install use wall anchors to attach the vanity to the wall. Reinstall the cabinet doors put the drawers back in place and go have a beer. If you attach a countertop to the wall with absolutely no cabinets whatsoever then use the same bracing techniques on both sides. The point where two counters meet in a corner must be square.

For a tight fit screw the angles to the cabinet first and then draw the top down to meet the steel angle with the second screw. Cut the boards 2 inches shorter than the depth of the countertop with a circular or table saw. Slide the end of the countertop over the horizontal stud. Attach three 1 inch by 4 inch wood boards to the wall brace board to hold the countertop.

Be sure to place pressure sticks along the back corners where the corner blocks are located to get the countertop down tight. If you re working with bare plywood or particleboard place nails vertically down through the top of the countertop spaced about 4 inches. The fascia laminates and backsplash can now be added. Attach the vanity to the wall using 3 inch drywall screws.

Retape the strip in place. When you measure for your countertop be sure to include the counter overhang which is usually between 3 4 1 inch in front and on open ends. Push the strip back tight against the wall using the combination square to verify the overhang depth. Attach the countertops to the cabinets.

Steel angles with 5 8 in. Seal any gap between the backsplash and the wall or along the edges and the wall with a clear silicone acrylic caulk. Run the tip of the compass along the wall with the pencil on the cardboard to transfer the contours of the wall to the strip.
