Granite Undermount Sink Installation

Installing a granite undermount sink can seem like a daunting task, but with the right tools and some patience, it can be done successfully. In this article, we will guide you through the step-by-step process of installing a granite undermount sink in your kitchen.

What is a Granite Undermount Sink?

A granite undermount sink is a sink that is installed from beneath the countertop, leaving the sink rimless and flush with the surface of the counter. This type of sink is popular because it provides a sleek and seamless look to any kitchen design. Granite undermount sinks are made from a durable, non-porous material that is resistant to stains, scratches, and other types of damage.

Tools Needed for Installation

Before you begin the installation process, you will need the following tools:

  • Electric Drill
  • Adjustable Wrench
  • Silicone Caulk
  • Plumber’s Putty
  • Sink Clips
  • Utility Knife
  • Measuring Tape
  • Screwdriver

Step-by-Step Guide to Install Granite Undermount Sink

Step 1: Measure the Sink

The first step in installing a granite undermount sink is to measure the sink and the countertop opening to ensure that the sink will fit properly. Measure the width and depth of the opening, and then measure the sink to ensure that it will fit comfortably.

Step 2: Prepare the Sink

Before installing the sink, clean it thoroughly with a non-abrasive cleaner and dry it completely. Apply a bead of plumber’s putty around the perimeter of the sink, leaving a 1/4 inch gap around the edge.

Step 3: Apply Caulk to the Countertop

Apply a thin line of silicone caulk around the perimeter of the countertop opening where the sink will be installed. Smooth the caulk with a caulk smoothing tool or your finger.

Step 4: Position the Sink

Position the sink in the countertop opening, making sure that it is centered and level. Press down firmly to ensure that the sink adheres to the caulk and putty.

Step 5: Secure the Sink with Clips

Using the sink clips provided, secure the sink to the underside of the countertop. Tighten the clips with an adjustable wrench to ensure that the sink is firmly secured to the countertop.

Step 6: Clean Up Excess Caulk

Use a utility knife to remove any excess caulk around the perimeter of the sink. Wipe away any remaining residue with a damp cloth.

Step 7: Connect Drain and Faucet

Connect the drain and faucet to the sink according to the manufacturer’s instructions. Use a wrench to tighten all connections securely.

Step 8: Test for Leaks

Turn on the water and check for leaks around the drain and faucet connections. Tighten any connections as needed to stop any leaks.

Once your granite undermount sink is installed, it is important to take proper care of it to ensure that it lasts for many years. Here are some tips for maintaining your sink:
