It’s very important to install an undermount kitchen sink before the countertop slabs are set down. Once the countertop slabs are set down, you usually will not be able to fit the sink through the hole, and you won’t be able to properly seal between the sink and the underside of the countertop.

Considering this, How do you attach an undermount sink to wood? Install a pair of flat under-mount sink clips, evenly spaced, at one side of the rim. To do this, hold a clip against the underside of the rim and perpendicular to the side of the sink, then drive a 1-inch wood screw through the machined hole in the clip and into the underside of the countertop.
