Black Quartz Undermount Sink for a Bold, Two-Station Kitchen
The Karran QU-610 is a 32-inch quartz composite undermount kitchen sink in Black, configured with a large bowl on the left and a smaller bowl on the right. Built from 80% natural quartz crystals and 20% acrylic resin, it brings a durable, matte-black presence to the counter while handling the split-station workflow most active kitchens depend on.
Key Features
• 80% quartz / 20% acrylic resin construction delivers highly scratch-, stain-, chip-, and heat-resistant performance suited to daily kitchen use.
• Large/small bowl configuration dedicates the deep primary bowl to washing while the secondary bowl handles prep, rinsing, or a disposal connection.
• Undermount installation seats the sink beneath the countertop with no exposed rim, keeping the counter surface clean and wipe-down easy.
• Black finish integrates with dark stone countertops and contrasts cleanly against light or white surfaces for a high-contrast design statement.
• No faucet deck on the sink body means the faucet and any accessories mount through the countertop, keeping the sightline uninterrupted.
Two Stations, One Undermount Footprint
The split-bowl layout earns its place in kitchens where one person is doing two things at once — soaking a pan on the left while prepping vegetables or draining pasta on the right. The large bowl takes the heavy lift, and the smaller bowl beside it handles the overflow without requiring a separate prep sink. Because the QU-610 undermounts beneath the countertop, the counter edge finishes cleanly around both bowls, making it easy to sweep scraps directly into the basin without catching on a rim. The faucet mounts through the countertop deck behind the sink rather than through the sink body itself, so there is no deck surface to work around.
Quartz Composite Built for Black Without the Maintenance
Quartz composite in Black is one of the more demanding finishes to maintain in a kitchen sink — chips, scratches, and hard-water deposits all show up against a dark ground. Karran's 80-20 quartz-resin formula addresses that directly: the high quartz content resists the surface scratches and staining that accumulate from daily use, and the material holds its matte finish without requiring sealing. The Black colorway runs through the full depth of the composite, so minor surface contact does not reveal a different color underneath. This is an indoor sink designed for standard residential plumbing conditions; it is not rated for outdoor installation.
The Right Fit for Dark or Contrast-Forward Kitchen Designs
Cabinet shops and designers specifying a kitchen where the sink is meant to read as a design element rather than disappear into the counter will find the QU-610 Black a straightforward specification. It works in quartz and granite countertop installations where undermounting is the standard path, and it pairs with Black or Gunmetal Grey faucets from Karran's kitchen faucet line for a finish-coordinated setup. Contractors replacing an existing undermount sink should verify the cabinet opening and countertop cutout dimensions against the sink's overall size before proceeding, since the large/small bowl footprint differs from equal-bowl or single-bowl predecessors. A drain assembly and mounting hardware are not included with the bare sink and will need to be sourced separately.
Does this sink work with quartz and granite countertops?
Yes. The QU-610 is a standard undermount sink designed for quartz, granite, and solid surface countertops using conventional undermount installation methods. It is not a seamless-series sink, so it does not use the bevel-bit laminate fabrication path — but it fits the standard stone and quartz undermount workflow without modification.
Which bowl is larger, and which side does each sit on?
The large bowl is on the left and the small bowl is on the right as the sink faces you from the front. The model suffix LH/LG and RH/SM in the product data confirms this orientation. If your layout favors the large bowl on the right, check the QU-610 family for a mirror-image configuration.
Does the drain or a grid come in the box?
No. The QU-610-BL is sold as a bare sink. Basket strainers, bottom grids, and Luster Pro oil are included with Karran's -PK1 pack versions; if you want those components bundled, look for the -PK1 SKU in this family. Otherwise, plan to source a drain assembly separately.
Where does the faucet mount on this sink?
There are no faucet holes in the sink body. The faucet — and any soap dispenser or secondary fixture — mounts through drillings in the countertop behind the sink. This is standard for the QU undermount line and keeps the sink profile clean, but it does mean the countertop fabricator needs to plan the hole placement before the slab is set.
A Sink That Works as Hard as the Kitchen Around It
The QU-610 in Black delivers a two-station quartz undermount setup that anchors the sink zone without demanding extra maintenance — the right call for kitchens where performance and finish both matter.
