Black Quartz Double Bowl Sink for Serious Kitchen Work
The Karran QU-810-BL is a 32-3/8 inch undermount double equal bowl kitchen sink crafted from quartz composite. Its deep Black finish and 9 inch bowl depth make it a workhorse center-point for busy kitchen countertops in quartz, granite, and solid surface installations.
Key Features
• Quartz composite construction — 80% natural quartz crystals and 20% high-performance acrylic resin for a sink that resists scratches, stains, chips, and heat.
• Heat resistant to 535°F — handles hot pans and cookware without damaging the bowl surface.
• Double equal bowl configuration — two identically sized basins support a dedicated wash-and-rinse workflow side by side.
• Undermount design with no faucet deck — faucet and accessories mount through the countertop, leaving the basin accessible from edge to edge.
• Deep 9 inch bowl depth — accommodates large pots, sheet pans, and tall cookware without splashing.
• Black finish throughout — the color runs through the full composite body, so minor surface wear does not expose a contrasting layer beneath.
Built for High-Traffic Kitchen Installations
Two equal-depth bowls let one side hold soapy wash water while the other handles rinsing or prep work, a practical split that anyone cooking daily or running a production kitchen will recognize immediately. The 9 inch bowl depth gives clearance for the largest stockpots and sheet pans without wrestling them over a shallow rim. Because the faucet mounts through the countertop rather than a sink deck, there is more usable basin area and no seam where the deck meets the bowl to trap food debris. The QU-810-BL undermounts beneath the countertop surface, so the counter edge wipes clean in one pass — no rim channel to scrub around.
Quartz Composite in Black: Material and Durability
Quartz composite — 80% crushed quartz and 20% acrylic resin — produces a bowl that is harder and denser than single-material acrylic and more impact-tolerant than fired ceramic. The material is highly scratch resistant, highly stain resistant, and rated to withstand heat up to 535°F, so a cast iron skillet rested briefly on the bowl bottom is not a concern. The Black color is integral to the composite body, not a surface coating, which means everyday contact with utensils and cookware will not reveal a lighter substrate underneath. Routine cleaning requires only mild soap and water; the non-porous surface does not harbor bacteria or require sealing. This sink is designed for indoor kitchen use with the plumbing and countertop materials the undermount installation requires.
The Right Sink for Renovators, Designers, and Working Shops
Cabinet shops and millwork fabricators building kitchen packages in quartz or granite will find the QU-810 a straightforward undermount specification — the flat mounting rim accommodates a standard reveal in stone and solid surface without specialized tooling. Homeowners renovating a kitchen who want the visual impact of a dark sink paired with light stone countertops get a color-through bowl that holds up to the contrast for years. Kitchen designers specifying for residential projects can call out the QU-810-BL with confidence across styles from contemporary to transitional, since the matte Black composite reads equally well against warm wood cabinetry and cool painted faces. At 32-3/8 inches overall, the sink fits a 36 inch base cabinet with room for the faucet drilling.
Does the faucet mount to the sink or to the countertop?
The QU-810 has no faucet deck, so the faucet and any accessories such as a soap dispenser mount through the countertop behind the sink. This gives you full flexibility in faucet placement and keeps the full bowl width open.
Is a mounting template or sink clips included with this sink?
Karran QU Series sinks are sold without a paper template or mounting clips — per the series documentation, both are not included. Check with your countertop fabricator, as many use the actual sink or a downloaded DXF file for the cutout rather than a paper template.
Will this sink work under granite or quartz countertops?
Yes. The QU-810 is designed for standard undermount installation in stone countertops including granite and quartz, as well as solid surface. It is not a seamless-series sink; the countertop edge and mounting rim are finished in the conventional undermount fashion. A professional fabricator should cut and mount the sink.
Are the two bowls exactly the same size?
Yes. The QU-810 is a double equal bowl configuration — both basins share the same dimensions and depth, so there is no larger or smaller side to account for when planning the plumbing rough-in.
Does the Black finish show water spots or scratches over time?
Because the color runs through the quartz composite body, light surface contact will not expose a contrasting layer. Like any dark sink, it may show mineral deposits from hard water more readily than a lighter finish — a quick wipe with a damp cloth after use keeps the surface looking its best.
A Kitchen Sink That Stays Black, Works Hard, and Installs Clean
The QU-810-BL brings together a deep double-bowl layout, color-through quartz composite durability, and a true undermount profile that makes countertop cleanup straightforward — a combination built to hold up in a working kitchen for the long term.
