Bold Black Finish, Drop-In Simplicity
The Karran QT-710 is a top mount double equal bowl kitchen sink crafted from quartz composite and finished in Black. It drops into a standard countertop cutout without requiring a professional stone installer or specialized fabrication tools, making it a practical choice for kitchen renovations and cabinet shop installs alike.
Key Features
• Quartz composite construction — 80% natural quartz crystals bound in 20% high-performance acrylic resin for a dense, durable bowl that resists scratches, stains, chips, and heat.
• Top mount installation — the sink drops into a standard countertop cutout from above and seats on its perimeter rim, compatible with virtually every countertop material.
• Double equal bowl configuration — two identically sized basins support a classic wash-and-rinse workflow or split food prep across both sides.
• Black finish — a consistent, non-fading quartz color that runs through the material rather than sitting as a surface coat.
• 33 x 22 x 9 inch overall dimensions — a full-size footprint that fits a standard 33 inch or larger sink base cabinet.
Where This Sink Earns Its Place
Top mount installation is the fastest path from box to running water. Trace the outline, cut with a jigsaw, lower the sink into the opening, and clamp from below — no countertop edge finishing, no reveal negotiation with the fabricator, and no restriction on countertop material. That accessibility makes the QT-710 well suited to laminate kitchens, butcher block counters, and tile installations where an undermount cutout edge would either be impractical or require extra labor to finish.
The equal bowl split works best for households and small commercial kitchens that run distinct wash and rinse stations, or where two cooks share the sink at once. Neither bowl compromises on the other, and the 9 inch depth gives each side enough room to handle stock pots and full-size cutting boards.
Quartz Composite in Black: Material That Earns Its Keep
Quartz composite at 80% quartz content behaves like a hard mineral surface rather than a coated one. Scratches from knives and abrasives that would mark a painted or enameled finish do not penetrate the material the same way, and heat from hot pots is absorbed gradually rather than damaging the surface on contact. The Black color in Karran's quartz line is integral to the composite mix, so the finish does not chip away to reveal a lighter substrate underneath. Over time the surface stays consistent without the refinishing or resealing that natural stone periodically needs.
The Right Fit for This Sink
Designers specifying a matte black sink for a contemporary or industrial kitchen will find the QT-710's color consistent and repeatable across orders, which matters when coordinating with matte black faucets and hardware across multiple units in a project. Cabinet shops installing production kitchens benefit from a top mount format that does not depend on countertop material or require the countertop to be in place first. Homeowners renovating on a schedule appreciate that the install does not require a return visit from a stone fabricator. The 33 inch format works in any sink base that accepts a 33 inch or wider sink, keeping cabinet selection straightforward.
Frequently Asked Questions
Does this sink require a special cabinet or base?
A standard 33 inch or larger sink base cabinet accommodates the QT-710. No modification to the cabinet or face frame is required for a top mount installation.
Can this sink be installed in a laminate countertop?
Yes. Because the perimeter rim sits on top of the counter, the cut edge is covered, which makes top mount the preferred method for laminate. The rim seals against the surface with silicone and the clips draw it down from below.
Is the Black color a surface coating or part of the material?
The color is integral to the quartz composite mix, not a surface coat. This means minor abrasion does not expose a lighter layer underneath, and the finish remains consistent over time without painting or resealing.
Does the sink ship with mounting clips or a drain?
Confirm included hardware at checkout. Karran's QT Series sinks vary by pack — a drain assembly is not included with the bare sink and should be ordered separately if not already on hand.
Will this sink work with my existing faucet drillings?
The QT-710 does not have a faucet deck, so the faucet mounts through the countertop behind the sink. Match your faucet's hole pattern to your countertop's drillings rather than to the sink itself.
A Sink That Installs Fast and Looks the Part for Years
The QT-710 brings a full-size, hard-wearing double bowl to any kitchen that can accept a standard 33 inch top mount drop-in, with a Black quartz finish that holds its appearance without ongoing maintenance.
