Cut and Attach the 2x4s

Cut the 2x4s to length to act as supports for the sink: one across the back and two on the sides.

Measure the height of the sink and transfer that measurement to the cabinet. Attach the 2x4 supports.

Step 1

Attach the Ledger Supports

Measure where the feet are on the sink, and attach the ledger supports across the width of the cabinet. Cut 1x support boards the width of the cabinet, place them on top of the 2x4s and screw them down.

Step 2

Cut the Cabinet and Install the Sink

Measure the sink and mark the front of the cabinet for the area to be cut out. Place painter’s tape along the cut mark to protect the cabinet. Make the cutout with a jigsaw, and set the sink in place.
