Karran Quartz Undermount Sink For High-Demand Kitchen Workstations
The Karran QU-810 is a double equal bowl undermount kitchen sink made from an 80% quartz and 20% acrylic resin composite, offered here in White. Its flat mounting rim fits beneath the countertop for a clean, exposed-edge finish, and its symmetrical bowl layout gives equal space on both sides of the divider for a wash-and-rinse workflow or two simultaneous prep tasks.
Key Features
• Heat resistant to 535°F so the bowl handles hot cookware without damage to the surface.
• Double equal bowl configuration divides the interior into two matched basins for versatile kitchen workflows.
• Quartz composite construction (80% quartz, 20% acrylic resin) delivers high resistance to scratches, stains, and chipping in daily use.
• Flat mounting rim secures beneath the countertop with a small positive or negative reveal, compatible with quartz, granite, and solid surface countertop materials.
• 9-inch bowl depth provides ample room for large pots, colanders, and sheet pans in both basins.
• No faucet deck keeps the countertop surface unbroken; faucet and accessories mount through the countertop behind the sink.
Where the Equal-Bowl Layout Earns Its Keep
A double equal bowl is the right call when the sink needs to serve two distinct jobs at the same time. One side holds soapy wash water while the other stays open for rinsing or draining. In a busy kitchen, that separation also lets two people work side by side without getting in each other's way. The 32-3/8-inch overall width fits a standard 33-inch or larger sink base cabinet, and the 19-1/4-inch front-to-back dimension works with typical 24-inch-deep base cabinet runs. Because the sink undermounts, there is no visible rim collecting debris at the counter edge — the countertop surface wipes straight into the bowl.
The flat mounting rim is compatible with quartz, granite, and solid surface countertops. If your countertop is laminate and a seamless flush finish is the goal, that application calls for a Q Series sink rather than this QU model. For stone, engineered quartz, and solid surface work surfaces, the QU-810 undermounts cleanly with a small positive or negative reveal decided between the fabricator and the client before cutting.
A Surface That Stands Up to the Sink's Busiest Days
Quartz composite wears differently than stainless steel or porcelain. It does not show water spots or fine scratches the way brushed metal does, and its matte texture stays consistent rather than showing use patterns at the center of the bowl. The White color is consistent through the material rather than a coating over a different substrate, so minor surface contact does not expose a contrasting layer. The 535°F heat threshold means a pot pulled directly from a burner can land in the bowl without the risk of thermal shock or surface damage that would concern you with some other sink materials. Routine cleaning with mild soap and water is all the maintenance this surface typically needs.
The Right Buyer for This Sink
Cabinet shops specifying a complete kitchen package will find the QU-810 straightforward to include in a standard undermount plan for stone or solid surface tops. Designers working on kitchen renovations where the countertop material is already set can size the QU-810 against the existing sink base without requiring a specialty cabinet. Homeowners doing a full kitchen remodel who want a durable, low-maintenance bowl in White — and whose countertop is quartz, granite, or solid surface — get a sink that handles daily volume without demanding much in return. Contractors who install a lot of stone-top kitchens will recognize the flat-rim undermount installation as familiar territory, requiring no special tooling beyond their standard undermount process.
Does this sink work with laminate countertops?
The QU-810 undermounts into quartz, granite, and solid surface countertops. For a laminate top where the goal is a seamless, flush installation, look at Karran's Q Series, which is documented for that application and uses a different rim profile designed for the laminate fabrication method.
Where does the faucet mount?
This sink has no faucet deck. The faucet, soap dispenser, and any other accessories mount through the countertop immediately behind the sink, which is standard practice for undermount quartz sinks paired with stone or solid surface tops.
Are the two bowls the same size?
Yes. The equal bowl layout splits the interior into two matched basins — same width, same depth, same usable area — so neither side is noticeably larger than the other. If you need a larger primary bowl alongside a smaller prep bowl, look at a large/small bowl configuration.
Are clips and a template included?
No. Mounting clips and a cutout template are not included with Karran QU Series sinks. Your fabricator will use their standard undermount hardware and should have the actual sink on hand before making the cutout.
Reliable Performance in White, Day After Day
The QU-810 brings together a practical equal-bowl layout, a surface that resists the wear of an active kitchen, and a clean undermount profile that suits fabricators and installers working with today's most common countertop materials — all in a White finish that stays consistent through years of use.
