The Ultimate Guide to Installing a Drop-In Kitchen Sink: Step-by-Step Instructions & Benefits

A drop-in sink is designed to be installed from above the countertop. It has a rim or lip that snaps onto the countertop, thus securing it in place. Unlike undermount sinks, which are installed below the countertop, drop-in sinks are easier to install and are suitable for a variety of countertop materials, including: engineered stone, natural stone, laminate, stainless steel.

The tools you need to prepare before installing a built-in sink include mildew-proof and waterproof glass glue; a screwdriver, and sometimes you even need to use an electric drill; fixing clamps, because some sinks require additional reinforcement; a tape measure and a marker to record the size of the sink to avoid drilling the wrong hole; a curved saw is used to cut the countertop.

Here are the steps to install an undermount sink:

Step 1: Measure & Mark the Cutout

• Place the sink upside down on the countertop and trace its outline.

• Measure the manufacturer’s recommended cutout dimensions.

• Use a jigsaw to carefully cut along the marked lines.

Step 2: Apply Sealant

• Run a bead of silicone sealant along the sink’s rim to prevent water leakage.

Step 3: Position & Secure the Sink

• Carefully lower the sink into the cutout.

• Press down to ensure a tight seal with the countertop.

• Use clips or brackets (if included) to secure the sink underneath.

Step 4: Connect Plumbing

• Attach the drain assembly and water supply lines.

• Check for leaks by running water.

Step 5: Final Check & Cleanup

• Wipe away excess sealant.

• Ensure the sink is firmly in place before regular use.

What are the benefits of using a built-in sink? First of all, it is easy to install, especially for people who live alone and need to complete the installation by themselves.
