An Undermount Double Bowl Built for Demanding Kitchens, in Black
The Karran QU-710 is a quartz composite undermount kitchen sink with two equal-sized bowls, designed for the heavy daily use of a primary wash station. It mounts beneath the countertop for a clean, wipe-to-edge surface, and its Black finish brings a bold, grounded look to any kitchen renovation or cabinet install project.
Key Features
• Quartz composite construction — made from 80% natural quartz crystals and 20% acrylic resin for a surface that resists scratches, stains, chips, and heat.
• Double equal bowl layout — two matched basins let you run a wash side and a rinse side simultaneously without sacrificing capacity on either.
• Undermount installation — the sink attaches beneath the countertop with no exposed rim, leaving the counter edge clean and easy to wipe down.
• Black finish — a deep, consistent color that coordinates with matte and dark hardware across modern and transitional kitchen designs.
• No faucet deck — the sink has no deck area, so the faucet and any accessories mount through the countertop, keeping the sink footprint clean.
Where the QU-710 Fits in the Workflow
A double equal bowl at this size suits kitchens where two people often work at the sink at once, or where hand-washing dishes is a regular routine alongside food prep. Both bowls carry equal depth, so there is no compromise bowl for one task or another. Cabinet shops and contractors fitting kitchens that call for a bold, dark sink will find this one ready for a standard 36-inch sink base cabinet, with the faucet drilling going through the stone, quartz, or solid surface counter above it. The undermount path is the correct one here: no rim sits proud of the counter, so liquids and crumbs wipe straight from the counter edge into the bowl.
Quartz Composite in Black: Material and Durability
The 80% quartz and 20% acrylic resin composition is what separates this sink from a stainless or acrylic alternative. The quartz content gives the bowl its resistance to scratches and chips from dropped pots and utensils, while the resin binding keeps the surface nonporous enough to resist staining from coffee, wine, and cooking oils. Heat resistance is a real advantage at a wash station where boiling pots come directly from the range. The Black colorway is consistent through the full depth of the material, not a surface coating, so chips and scratches do not expose a contrasting color underneath. That makes this a practical choice in high-traffic kitchens, not just a style one.
Right for This Project
Designers and homeowners specifying a dark kitchen where the sink is a focal point will find the Black quartz composite delivers the look without the maintenance demands of a polished surface. Cabinet shops outfitting a kitchen renovation where the client wants a striking undermount sink paired with stone or solid surface countertops will appreciate that the installation path is conventional: clips and fasteners per the countertop manufacturer's method, with the faucet drilled through the counter. This is an indoor sink for a primary kitchen station. Drain, template, and mounting clips are not included with the sink and are purchased separately to match the countertop material and installation method.
Frequently Asked Questions
Does this sink install seamlessly like Karran's Q Series?
No. The QU-710 is a conventional undermount sink in Karran's QU Series. It mounts beneath the countertop with clips and fasteners but does not use the seamless bevel-bit method. Seamless installation is specific to Karran's Q Series in laminate and solid surface countertops.
What countertop materials work with this sink?
The QU-710 undermounts in quartz, granite, and solid surface countertops using the countertop manufacturer's recommended method. Because it has no exposed rim, the counter edge must be finished to meet the sink bowl cleanly.
Where does the faucet mount?
The QU-710 has no faucet deck, so the faucet, soap dispenser, and any accessories mount through drillings in the countertop itself. Plan for the countertop fabricator to drill the needed holes before installation.
Is a drain or installation template included?
Neither a drain assembly nor a mounting template ships with this sink. Both are sold separately. Have the actual sink on hand before making any countertop cuts.
How do I care for the Black quartz surface?
Wipe the sink down regularly with a mild, non-abrasive cleanser. Avoid harsh scrubbing pads that can dull the surface over time. The quartz composite is highly stain resistant, but prompt cleanup of strong colorants keeps the finish looking its best.
A Practical Black Sink Built to Last
The QU-710 brings together quartz composite durability and a striking Black finish in a double equal bowl format that handles the full demands of a primary kitchen. It is a dependable specification for installers and a confident choice for homeowners who want a sink that works as hard as it looks.
