Undermount sinks are increasingly popular for kitchen renovations, offering a sleek, modern look and easy-to-clean surface. However, installing one in a wood countertop can be tricky. We’ll guide you through the steps of how to install an undermount sink in a wood countertop.

Cut Your Countertop

Before installing an undermount sink, you need to cut the hole in the countertop where the sink will be placed. Make sure the hole is slightly smaller than the sink, so that the edges of the sink sit snugly under the countertop. Use a jigsaw to make the cut, and don’t forget to wear protective eyewear.

Sand the Edges of Your Sink Cut-Out

Once you have cut the hole in the countertop, you need to sand the edges of the cut-out. Use a high-grit sandpaper to smooth out the rough edges so that you don’t scratch your hands when using the sink.

Apply Sealant

Before installing the sink beneath the hole, apply a bead of waterproof sealant around the edges of the sink. This will prevent moisture from seeping in between the wood and rim of the sink during use.

Attach Sink Clips

Next, attach the sink clips to the underside of the countertop. These clips will hold the sink securely in place. Make sure they are positioned correctly and are tightened correctly to avoid any movement or wobbling of the sink.

Mount the Sink

Carefully raise the sink to align with the hole from beneath, making sure that it’s centered and level. Use a wood clamp between the sink hole and countertop to hold the sink in place while the sealant dries. Then, attach the sink clips to the rim of the sink, tightening them to secure the sink to the countertop. Now you know how to install an undermount sink in a wood countertop.
