Karran 32"W x 21-1/4"D Quartz Black Double 60/40 Bowl Undermount Sink - QU-811-BL

Karran QU-811-BL Sink For Busy Kitchens

Karran QU-811-BL sink is a 32-3/8 inch wide by 21-1/4 inch deep double bowl quartz undermount unit that provides a large work area for kitchen tasks while keeping the footprint controlled for typical cabinet layouts. The 60/40 large and small bowl configuration lets installers and users dedicate the larger left bowl for washing and prep while the right bowl handles rinsing or secondary tasks, keeping workflow organized. Each bowl has a 9 inch depth, so the sink handles deeper pots and pans without excessive splash, which helps the surrounding countertop area stay drier in everyday use. Made from 80% natural quartz crystals and pure acrylic resin, the sink offers a solid-feeling work surface that supports regular kitchen duty. The black quartz finish ties into darker countertop designs, helping projects achieve a coordinated, modern appearance in the sink zone.

Quartz Double Bowl Details That Add Value

• The external bowl dimensions of 32-3/8 inches by 21-1/4 inches by 9 inches define a substantial working sink area, giving fabricators and installers clear sizing for layout while still fitting common kitchen cabinet runs.
• The left bowl dimensions of 16-1/2 inches by 21-1/4 inches by 9 inches create a generous primary basin, allowing users to handle large cookware and prep tasks without feeling cramped during regular kitchen use.
• The right bowl dimensions of 11-1/2 inches by 16-3/4 inches by 9 inches provide a compact secondary basin, which supports rinsing, soaking, or separate prep work while keeping tasks divided for cleaner workflow.
• Construction from 80% natural quartz crystals and pure acrylic resin creates a solid composite structure, giving the sink a dense feel and supporting long-term service in busy residential kitchen environments.
• The quartz material is non-porous, prohibiting the spread of germs and bacteria, which helps kitchens maintain a cleaner sink surface and simplifies day-to-day cleanup for users.
• Heat safety up to 535 degrees Fahrenheit, with resistance to rapid temperature changes from hot and cold water, allows normal hot pot handling and sink use without concern about routine thermal stresses.

Undermount Quartz Sink Layout And Fit

This quartz double bowl sink is designed for undermount installation, so it mounts beneath the countertop and creates a clean edge that makes wiping debris directly into the bowls straightforward in daily use. The external bowl dimensions of 32-3/8 inches by 21-1/4 inches by 9 inches help fabricators plan cutouts and cabinet spacing, supporting predictable fits in typical kitchen base configurations. With both bowls at 9 inches deep, the vertical clearance is consistent across the sink, which simplifies planning for drain connections and under-sink component layouts. All external dimensions are approximate to 1/4 inch, which gives installers a defined tolerance range when coordinating countertop fabrication, cabinet clearances, and sink positioning in the run.

How This Quartz Sink Supports Kitchen Work

Where This Double Bowl Sink Works Best

This quartz black double 60/40 bowl undermount sink fits kitchen projects that call for a distinct primary washing area plus a smaller support bowl, giving designers flexibility in how the wet zone is organized. The left bowl dimensions of 16-1/2 inches by 21-1/4 inches by 9 inches provide a strong main work basin, so tasks like washing baking sheets or stock pots fit within the bowl instead of over the countertop edge. The right bowl dimensions of 11-1/2 inches by 16-3/4 inches by 9 inches suit secondary uses such as holding a colander or handling quick rinses, which helps users separate cleaner tasks from heavier washing. The black color option ties into darker or contrasting countertop choices, so this sink serves both as a work tool and as a visual anchor in the kitchen layout. Sinks in this series are available in six colors - white, bisque, black, brown, concrete, and grey - supporting a range of design schemes when planning multiple projects.

Details That Support Consistent Performance

The construction using 80% natural quartz crystals and pure acrylic resin creates a dense, composite structure that stands up to repeated kitchen use while maintaining a solid feel under pots and pans. The non-porous quartz material prohibits the spread of germs and bacteria, which supports hygienic food prep zones and helps users keep the sink surface cleaner with routine washing. Heat safety up to 535 degrees Fahrenheit, along with the ability to withstand rapid temperature changes from hot and cold water, allows normal kitchen workflows that move from cooktop or oven to sink without concern about typical thermal shock. Both bowls share a 9 inch depth, so drain routing, trap placement, and accessory planning stay consistent from side to side, streamlining under-sink layout decisions. A 25 years Limited Warranty against manufacturer defects backs the sink, giving contractors and homeowners confidence that the manufacturer stands behind the quartz construction over long service life expectations.
