It maximizes usable counter space and lets you stand comfortably at the cutting board, making prep easier and more enjoyable. Most diagonal corner cabinets measure 36" from the corner of the wall in both directions, and our standard diagonal corner sink is built to fit that layout perfectly.

If your kitchen plan truly requires a corner sink, you’re in the exact situation that inspired me to reinvent the category. For years, homeowners were stuck with clunky double-bowl “butterfly” corner sinks that wasted space and made prep uncomfortable. I designed one of the first true single-bowl corner sinks to solve that problem, turning an awkward corner into a highly functional workstation. Today, our corner sinks blend efficiency, comfort, and clean design, all built to fit your exact cabinetry and workflow.
