Undermount Sink

Undermount sinks install beneath the countertop, with the counter material extending over the sink rim. This creates a seamless transition that makes cleanup effortless—crumbs and water sweep directly into the basin without catching on a lip. The clean aesthetic suits modern and transitional kitchens particularly well. However, undermount installation requires solid surface countertops (stone, quartz, or solid surface)—laminate counters cannot support undermount sinks.

Placement & Usage Tips

The countertop edge profile matters—eased or bullnose edges work best over undermount sinks. Avoid sharp square edges that collect water. Ensure adequate support clips for heavier sink materials.

💡 Pro Tip

Stainless undermounts are most forgiving during installation. Fireclay and cast iron require precise cutouts and robust support due to weight. Always confirm your fabricator has undermount experience.
