The cons: outdated double bowl or butterfly corner sinks that waste counter space and force you to reach over dividers. You end up with water all over the countertops, and many cooking items will not fit in either bowl. Most importantly, watch out for the imported cheap copycats offering black and other colored corner workstation sinks. The colored coating on the interior of any stainless steel sink will NOT last! We don't care what the warranty says. We will stake our reputation on it. A PVD finish can scratch, chip, and lose luster during use. Just ask any AI source.

Each corner sink workstation is engineered to improve reach, workflow, and usability, turning an overlooked corner into a fully functional workspace. With built-in accessories like sliding cutting boards, colanders, and drying racks, Rachiele corner sinks streamline meal prep and cleanup.

Corner Kitchen Sink Solutions for Every Home
If you have a diagonal corner cabinet, we’ve designed a single-bowl corner sink that turns that space into a true workstation. 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.
We’ve designed replacement corner sinks for homeowners for more than 27 years, and the process is simple. We’ll walk you through everything from start to finish so the transition is smooth and stress-free. If you’d like, you can schedule a Zoom call with Dino to review options and sizing with zero sales pressure.

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.
A corner sink cabinet should always be designed after the sink is finalized. Even a small dimensional compromise can transform a highly functional corner sink into a daily frustration. The cabinet is simply the support structure - the sink is the working tool used every day.
Because we do not advertise and intentionally maintain a relatively low online profile, many cabinet designers may not yet be familiar with the capabilities of a true custom single bowl corner workstation sink. It is important to make them aware that a fully custom solution is possible and to hold off on final cabinet dimensions until the sink design has been properly developed.

Diagonal corner sink: The bowl sits at a 45-degree angle across the corner, fitting into a diagonal corner cabinet. The front face of the sink faces the cook directly, making it the most ergonomic corner option. The standard diagonal corner cabinet measures 36 inches from the corner wall in both directions.
L-shaped corner sink: The bowl wraps along two walls in an L configuration, following the cabinet line rather than cutting across the corner at an angle. This design works in kitchens where the corner cabinet runs parallel to the walls rather than diagonally.
Absolutely. During your Zoom consultation, Dino personally reviews your cabinet dimensions and kitchen plans to confirm the sink will fit precisely before a single piece of metal is cut. Every measurement is verified in advance so there are no surprises during installation
In most cases yes - and this has been one of our specialties for 27 years. Replacing a double bowl corner sink without replacing your countertops is typically a one-day process.

In 27 years of replacement installations, 100% have been completed without issue.
Choosing the right size for a corner kitchen sink begins with a conversation, not a catalog.
