Project Resources


Step 1

Cut the 1 x 6  board to length (30 inches for this mirror). Sand smooth with 120-grit and 180-grit sandpaper. While sanding, lightly round over the front edges, both ends and the front corners.

Good to Know

If you don’t have a suitable saw, ask a Lowe’s associate to trim the factory end from the board and cut it to length.

Step 2

Drill a total of four holes 3 inches and 11 inches from both ends and 3/8 inch from one edge (Project Diagram). Add countersinks to the bottom face.

Step 3

Hold the board in position on the bottom edge of the mirror frame and transfer the pilot holes to the frame. Remove the board and drill the pilot holes 1 inch deep.

Good to Know

Tape your drill bit to control the depth of the holes you drill in the mirror. Avoid drilling so deep into the edge of the frame that the bit touches the mirror glass. Don’t skip this step, though. Failing to drill pilot holes may cause the mirror frame to crack.

Step 4

Paint the shelf to match the factory finish on the mirror (Pontoon White shown), or apply a new color to both.

Step 5

Screw the shelf to the mirror using the pilot holes. If you prefer, touch up the heads of the screws with paint to match the shelf.
