Karran 32"W x 19-1/2"D Quartz Concrete Double 60/40 Bowl Undermount Sink - QU-711-CN

Karran QU-711-CN Quartz Sink For New Countertops

Karran QU-711-CN quartz sink gives you a 32-1/2 inch by 19-1/2 inch double 60/40 undermount layout, so you get a large and small bowl that organize dish, prep, or cleaning tasks without crowding the base cabinet space. The internal bowls measure 17-1/2 by 15-3/4 by 9 inches and 11-3/8 by 15-3/4 by 9 inches, which sets clear capacity for stacking pans in the large side while the smaller bowl handles rinsing or prep work at the same time. Manufactured from 80 percent crushed quartz plus 20 percent acrylic resin, the sink creates a hard, consistent material that supports everyday kitchen use while maintaining a uniform appearance around the bowls and rim. A 1-1/4 by 3/4 inch machined resin matrix rim forms a precise undermount surface, which helps fabricators achieve tight, repeatable seams against the countertop edge.

Key Quartz Double Bowl Details That Matter

• The 60/40 double bowl layout gives one larger and one smaller basin, so installers can position the QU-711-CN to match how the user prefers to split washing and prep tasks across the sink.
• External dimensions of 32-1/2 inches by 19-1/2 inches define the cutout and cabinet space, helping layout planning for base cabinet sizing and adjacent components in the kitchen run.
• Internal bowl sizes of 17-1/2 by 15-3/4 by 9 inches and 11-3/8 by 15-3/4 by 9 inches give clear working depth and width, which helps assess pot clearance and usable sink volume.
• The 3-1/2 inch waste opening matches a common drain size, simplifying selection of compatible strainer baskets and downstream plumbing parts during installation.
• An 80 percent crushed quartz plus 20 percent acrylic resin construction creates a uniform quartz sink body, supporting consistent cutting, edging, and mounting during countertop fabrication.
• The matte finish on the sink bowl surface provides a non-gloss working area, which can coordinate with stone countertop textures and reduce visible glare around the basin.

Undermount Installation And Fit Considerations

Undermount installation is required for this Karran quartz kitchen sink, so the sink mounts beneath the countertop and relies on the machined rim to support the bond and alignment. The 1-1/4 by 3/4 inch resin matrix rim is machined, providing a consistent mounting surface that helps installers set an even reveal or flush finish along the sink opening. This sink can only be installed in new countertops, not in existing countertops with an existing sink cutout, which directs the product toward projects where the fabricator controls the original stone cutting. The QU-711-CN may be undermounted to all stone products, and a 1/8 inch overhang is recommended, allowing a slight countertop lip over the bowl edge that supports controlled drainage and a clean visual line at the opening.

How This Quartz Sink Fits Real Kitchen Projects

Where The Karran Double 60/40 Bowl Sink Works

This Karran 32-1/2 inch by 19-1/2 inch quartz kitchen sink fits into new stone countertop installations, positioning it well for remodel or new-build projects where the shop fabricates the tops from scratch. Because the sink may be undermounted to all stone products, it suits granite, quartz, and similar materials commonly run on CNC equipment in fabrication shops. The double 60/40 bowl configuration, with 17-1/2 by 15-3/4 by 9 inch and 11-3/8 by 15-3/4 by 9 inch bowls, supports kitchens that need a primary washing basin plus a secondary bowl for prep or soaking without needing two separate sinks. The 3-1/2 inch waste opening aligns with standard kitchen drain assemblies, so the sink integrates into typical residential plumbing layouts while leaving the strainer basket style as a finish decision.

Details That Support Repeatable Fabrication Results

The QU-711-CN quartz sink is manufactured from 80 percent crushed quartz plus 20 percent acrylic resin, giving fabricators a consistent composite material to work around when shaping and polishing the countertop cutout. Its 1-1/4 by 3/4 inch machined resin matrix rim creates a defined support ledge, which helps installers and shops achieve a uniform bond line and even undermount reveal along the full perimeter. Because digital templates for CNC machines are available at www.karran.com, shops using CNC fabrication can rely on accurate electronic files to generate repeatable cutouts and mounting details across multiple jobs. The recommendation for a 1/8 inch overhang, with the option for flush installation, provides clear guidance on edge treatment, enabling designers and installers to coordinate sink reveal style with the overall countertop profile while maintaining consistent drainage toward the basin.
