Review the dimensions and technical drawing, then contact us for available configurations and pricing.

Undermount sinks are installed beneath the countertop, creating a seamless transition from counter to sink. This makes it easy to wipe crumbs and spills directly into the basin without obstruction. However, undermounts require precise installation and are typically supported with special brackets and adhesives. They work best with solid-surface counters like quartz, granite, or marble since laminate surfaces may not support the weight. While more expensive, the sleek look and easy cleaning make undermounts a favorite among homeowners.
