How to Make and Install a Flushmount Sink and Countertop

Plastic laminate for countertops is durable, resistant to water damage, easy to maintain and affordable. You can choose patterns, colors and edge profiles that you won’t find with other countertop materials. Plus, you can use an undermount sink — and you can do it yourself. Installing our undermount sink from Karran required only basic tools. Here’s how we did it.

Placing and cutting out the sink

Mark the location of the sink on the substrate. Place the sink 2-1/2-in. back from the front edge of the countertop and centered on the cabinet. When you trace the sink shape onto the particle board substrate, keep your pencil vertical so the cutline is offset about 1/8-in. Drill a 1/2-in. starter hole and cut out the sink opening with a jigsaw.
