Self-rimming, overmount or drop-in sinks are the perfect choice for counter tops with a rough sink opening.

Whether you are replacing an old sink or adding a new one, installing a self-rimming sink is a reasonable, do-it-yourself kind of job.

Step 1: Determine the size of the sink by measuring the counter surface. Account for any under-the-sink obstructions such as drawers or plumbing fixtures. The sink should sit approximately 1 1/2 inches from the front edge of the counter and no more than 3 to 4 inches from the back splash or back edge of the counter top. If you have an existing hole, measure it after you have removed the old sink to determine the proper sink size.

Step 2: If you need to cut a hole for the sink, tape the template that came with the sink onto the counter. Use a pencil to trace the template. Drill a half-inch hole inside each corner of the template outline. Use a jig saw to cut away the excess counter top, creating a smooth straight hole to set the sink into.

Step 3: Set the new sink into the cutout area of the counter to ensure there are no obstructions.

Step 4: Remove the sink from the hole and clean the counter area where the sink is to be installed. Make sure the area is free of debris before proceeding.

Step 5: Before installing the sink, turn it upside down and properly attach the faucet to the sink. This will minimize the work you will need to do beneath the sink once it is installed.

Step 6: Apply a quarter-inch bead of 100 percent silicone caulk or plumber’s putty to the underside of the sink rim.

Step 7: Turn the kitchen sink right-side up and position it over the cutout area in the counter. Make sure the sink is properly aligned before pressing it firmly into place. Remove any excess silicone caulk or plumbers putty immediately.

Step 8: Most self-rimming sinks come with fastener clips used to anchor the sink to the counter top. Follow the manufacturer’s directions and secure the sink into place with the fastener clips.

Step 9: Clean up any excess silicone or plumber’s putty and attach the water supply and drain accessories. As you proceed you may find that setting the sink was indeed the easiest part of your plumbing project.
