Black Quartz Undermount Sink for a Two-Station Kitchen Workflow
The Karran QA-760 is a large/small bowl quartz composite undermount kitchen sink finished in Black, sized at 34 by 21-1/4 by 9 inches. Its unequal bowl layout divides a generous wash side from a smaller prep or rinse side, making it a natural fit for kitchens that handle real cooking volume every day.
Key Features
• 80% quartz / 20% acrylic resin construction delivers a surface that is highly resistant to scratches, stains, chips, and heat.
• Large/small bowl configuration separates the primary wash basin from a dedicated prep or disposal side.
• Undermount installation keeps the countertop edge fully exposed and wipe-clean, with no rim to catch food or debris.
• 9-inch bowl depth accommodates large pots, sheet pans, and tall cookware without splashing.
• Black finish holds its tone against everyday use and coordinates with matte black faucets and hardware.
• Faucet mounts through the countertop — the sink has no faucet deck, so the faucet and any accessories drill directly into the stone or solid surface behind the bowl.
Where the Two-Bowl Layout Earns Its Place
A large/small bowl split works best when the kitchen runs at volume: the large bowl holds a soaking pot or a full rack of dishes while the smaller side stays clear for rinsing produce, staging a cutting board over the drain, or running a disposal. For households that cook several nights a week — or cabinet shops, showrooms, and design studios with a working kitchen on site — that separation pays off during every cleanup. The 9-inch depth on both bowls means tall stockpots drop in without tipping, and the undermount profile keeps the countertop surface completely uninterrupted from front to back, which matters when counter space is tight and a backsplash is part of the design.
Quartz Composite in Black
The QA-760 is made from 80% natural quartz crystals bound in 20% high-performance acrylic resin — a formula Karran describes as highly scratch, stain, chip, and heat resistant. That combination holds up through years of daily use without needing the attention a stainless sink demands after contact with hard water or acidic foods. The Black finish is an integral color, not a surface coating, which means it does not chip away or fade to a different tone at the edges. It coordinates cleanly with dark hardware finishes and reads as a grounding design element in both contemporary and transitional kitchens. Because the faucet mounts through the countertop rather than through a deck on the sink, there is no visible chrome or satin plate breaking the basin's surface — the bowl itself stays visually clean.
Suited For Renovation and New Construction Alike
This sink is a good match for fabricators and cabinet shops specifying sinks for stone, quartz, or solid surface countertops. The undermount install goes in beneath a finished countertop edge, so it works whether the counter is being set new or the kitchen is being refreshed with new stone over existing cabinetry. Homeowners undertaking a full kitchen renovation who want a sink that disappears into the counter rather than sitting on top of it will find the QA-760's profile does exactly that. Designers specifying for clients who cook seriously — or who entertain regularly and need a prep side that stays usable during cleanup — will appreciate the unequal bowl split. The Black finish coordinates across Karran's quartz line, which simplifies hardware and accessory matching across a project.
Does the faucet mount to the sink or to the countertop?
The QA-760 has no faucet deck, so the faucet mounts through the countertop behind the bowl. Plan faucet hole locations with your fabricator before the countertop is cut.
Which bowl is larger — left or right?
Per the SAP description, the large bowl is on the left and the small bowl is on the right as installed. Confirm orientation from the spec sheet or with your fabricator before finalizing the cutout plan.
What countertop materials work with this sink?
The QA-760 is an undermount sink suitable for quartz, granite, and solid surface countertops. It is not a seamless-series sink, so it does not use the bevel-bit laminate method; the countertop edge is finished and the sink mounts beneath it with clips or adhesive per your countertop fabricator's method.
Are grids, strainers, or a drain included?
This listing is for the sink only. Basket strainers, bottom grids, and drain assemblies are sold separately. Check Karran's accessory fit tables to confirm the correct grid and strainer for each bowl.
How does the Black quartz finish hold up over time?
The Black color runs through the quartz composite material rather than sitting on the surface as a coating. Karran describes the material as highly scratch, stain, chip, and heat resistant — the finish does not chip or fade to a different tone at wear points.
One Sink That Handles the Whole Kitchen
The QA-760 in Black brings together a two-station bowl layout, deep 9-inch basins, and a durable quartz composite surface in a finish that anchors the kitchen's look for the long term — without the upkeep that lighter finishes or polished metals require.
