Concrete Finish and Equal-Bowl Symmetry in One Undermount
The Karran QU-810-CN is a 32-3/8 by 19-1/4 inch quartz composite undermount kitchen sink with two equal bowls, each 9 inches deep, finished in a warm Concrete tone. Made from 80% natural quartz crystals and 20% high-performance acrylic resin, it mounts beneath quartz, granite, and solid surface countertops for a clean, rimless work surface.
Key Features
• Double equal-bowl layout divides the sink symmetrically, giving each side the same working depth and footprint.
• Quartz composite construction combines 80% natural quartz and 20% acrylic resin for a material that resists scratches, stains, and chips through daily kitchen use.
• Heat resistant to 535°F so hot cookware set directly in the bowl won't damage the surface.
• Undermount installation leaves the counter edge exposed and uninterrupted, making cleanup a single wipe from counter to drain.
• Concrete color brings a neutral, matte-toned finish that coordinates with both warm wood cabinetry and cooler stone or laminate surfaces.
• 9-inch bowl depth on each side accommodates deep pots, large cutting boards, and full-size baking sheets.
Where the Equal-Bowl Layout Earns Its Keep
A symmetric two-bowl sink suits kitchens where the wash-and-rinse workflow matters as much as raw basin volume. One side holds soapy water while the other rinses; neither bowl feels like an afterthought. For households that hand-wash dishes regularly, or for cabinet shops and design studios with a sink in the break room or studio kitchen, equal bowls keep both stations productive. The 32-3/8 inch overall width fits a standard 33 inch sink base with comfortable clearance, and the 19-1/4 inch front-to-back depth leaves room for a deck-mounted faucet drilled through the countertop behind the sink.
Because the faucet mounts through the countertop rather than a sink deck, the QU-810 works cleanly alongside stone, quartz, or solid surface tops where the counter itself carries the faucet. That configuration also keeps the bowl area free of obstacles so each side stays fully usable.
Quartz Composite in a Concrete Tone
Concrete is a neutral mid-tone that reads warmer than grey and cooler than brown, making it one of the more versatile colorways in the quartz sink lineup. It pairs naturally with white shaker cabinetry, walnut or white oak faces, and matte black or brushed gold faucet finishes without competing with any of them. The quartz composite material carries that color through the full depth of the bowl, so chips or small nicks don't expose a white substrate underneath. The surface is non-glossy and matte in character, which also means it doesn't show water spots or fingerprints the way a polished finish would. Care is straightforward: a non-abrasive cleanser and a soft cloth keep it looking right without special treatments.
The Right Sink for a Serious Kitchen Build
Cabinet shops specifying for a kitchen remodel, designers sourcing for a renovation project, and homeowners building out a new kitchen will all find the QU-810-CN hits a practical middle ground. It's large enough to handle real cooking tasks but not so wide that it crowds a standard sink run. The Concrete finish gives it flexibility across a broad range of cabinet and countertop combinations, and the equal-bowl split avoids the compromise of an unequal layout where one side always feels too small. For installers, the flat mounting rim works with standard undermount clip and adhesive methods for quartz, granite, and solid surface countertops. Note that installation template and mounting clips are not included with this sink and should be sourced separately before fabrication begins.
Frequently Asked Questions
Does this sink mount seamlessly like Karran's Q Series?
No. The QU-810 is a standard undermount sink, not a seamless-series model. It mounts beneath the countertop with a flat rim using conventional clip and adhesive methods. Seamless flush-to-counter installation is specific to Karran's Q Series, which uses a different fabrication method for laminate and solid surface countertops.
What countertop materials work with this undermount?
The QU-810 is designed for undermounting in quartz, granite, and solid surface countertops. It is not a seamless-mount model, so it is not documented for the bevel-bit laminate method used with the Q Series.
Are template and mounting clips included?
No. This sink does not include an installation template or mounting clips. Both need to be sourced separately before the countertop cutout is made. A DXF file may be available for CNC cutouts; confirm with your countertop fabricator.
Is a drain or strainer included?
The QU-810-CN is a bare sink; drains and basket strainers are sold separately. You will need a strainer for each of the two bowl drains.
How does the Concrete color hold up over time?
The color runs through the quartz composite material rather than sitting on the surface as a coating, so it doesn't peel, fade, or chip away to reveal a different substrate. The quartz composite is scratch, stain, and chip resistant under normal kitchen use.
A Workhorse Sink That Looks Considered
The QU-810-CN delivers the depth, symmetry, and material durability a busy kitchen demands, wrapped in a Concrete finish that works across a wide range of design directions without calling attention to itself.
