TopZero sink installation, flush with the stone

TopZero is an engineered seamless sink system. A stainless basin is made to fit a precisely machined cutout, and the stone wraps over its edge with a hairline reveal.

From above, the countertop looks continuous into the basin. Stoneex Surfaces is TopZero Integrated Sinks Certified.
