How to Install an Undermount Bathroom Sink in a Granite Countertop

Installing an undermount bathroom sink in a granite countertop can enhance the aesthetics and functionality of your bathroom. Here's a comprehensive guide to help you through the process:

Materials and Tools Required

Undermount sink
Granite countertop
Sink template
Construction adhesive
Caulk
Masking tape
Drill
Hole saw
Circular saw
Jigsaw
Clamps
Level
Pencil or marking tool

Step-by-Step Instructions

1. Preparation

Position the sink template on the underside of the granite countertop and trace its outline using a pencil or marking tool. Ensure the template is centered and aligned correctly.

2. Cutting the Hole

Use a hole saw to cut a starter hole at one corner of the traced outline. Insert a jigsaw into the starter hole and carefully cut along the traced lines, creating the opening for the sink.

3. Installing the Clips

Apply construction adhesive to the clips and attach them to the underside of the granite countertop around the cutout. These clips will support the sink and prevent it from sagging.

4. Mounting the Sink

Apply a generous bead of construction adhesive to the sink flange and carefully lift the sink into the cutout. Place the sink into the clips and clamp it securely to hold it in place.

5. Connecting the Drain and Faucet

Connect the drain and faucet according to the manufacturer's instructions. Install the gaskets and tighten the connections to prevent leaks.

6. Caulking

Once the sink and connections are secure, apply a bead of caulk around the perimeter of the sink where it meets the countertop. Smooth the caulk with a wet finger to create a watertight seal.

7. Cleanup

Remove the masking tape and clean up any excess construction adhesive or caulk. Allow the caulk to dry completely before using the sink.

Tips and Precautions

Use a sharp hole saw and jigsaw blade to ensure clean cuts.
Wear safety glasses and gloves throughout the process.
Double-check the measurements before cutting the granite countertop.
Allow ample time for the caulk to dry before using the sink.
If you encounter any difficulties, do not hesitate to seek professional assistance.

By following these steps, you can successfully install an undermount bathroom sink in a granite countertop, enhancing the style and functionality of your bathroom.
