Mounting Undermount Bathroom Sink To Granite

Mounting Undermount Bathroom Sink to Granite: A Comprehensive Guide

Transforming your bathroom with an elegant undermount sink requires careful planning and precise execution. Installing an undermount sink on a granite countertop involves several essential aspects to ensure a flawless result and long-lasting functionality.

Preparing the Granite Countertop

Before mounting the sink, ensure the granite countertop has a precise opening cut to accommodate the sink. This opening should be slightly smaller than the sink's perimeter to allow for proper support and a tight fit. Use a diamond-tipped blade on a wet saw for a clean and precise cut.

Applying Adhesive

To secure the sink to the granite, select a high-quality bathroom or kitchen adhesive specifically designed for this purpose. Apply a generous bead of adhesive around the perimeter of the sink, ensuring it makes contact with both the sink and the granite.

Positioning the Sink

Carefully lift the sink and align it with the opening on the granite countertop. Slowly lower the sink into place, ensuring it sits flush against the granite surface. Use a level to check if the sink is level front to back and side to side.

Weighting the Sink

To provide additional support and prevent the sink from shifting during the curing process, place heavy weights or clamps around the perimeter of the sink. These weights will help maintain proper contact between the sink and the adhesive.

Curing Time

Allow the adhesive to cure completely for the recommended amount of time before removing the weights. The curing time varies depending on the specific adhesive used; always refer to the manufacturer's instructions.

Finishing Touches

Once the adhesive has cured, proceed with the remaining plumbing connections, such as the drain and faucet. Apply a bead of silicone caulk around the perimeter of the sink where it meets the granite to prevent water leakage.

Additional Tips

Use a sharp utility knife to clean any excess adhesive squeeze-out.
Avoid using acidic cleaners on granite countertops around the sink.
Periodically check the caulk seal and reapply as needed to maintain a moisture-resistant barrier.
