An Extra-Large Quartz Kitchen Sink Built for Heavy Daily Use
The Karran QT-722 is an extra-large single-bowl kitchen sink in Black quartz composite, designed for top mount installation in virtually any countertop material. Its 34 by 22 inch footprint and 9 inch bowl depth give busy kitchens a single uninterrupted wash station with genuine capacity for large cookware, sheet pans, and batch prep work.
Key Features
• Top mount installation drops the sink into an existing countertop cutout from above, making it compatible with laminate, solid surface, stone, and tile countertops.
• Extra-large single bowl at 34 by 22 by 9 inches delivers an unobstructed basin for oversized pots, baking sheets, and colanders.
• Quartz composite construction combines 80% natural quartz crystals and 20% acrylic resin for high resistance to scratches, stains, chips, and heat.
• Black finish provides a bold, consistent color throughout the material, so nicks and chips do not expose a contrasting base layer.
• Self-rimming design rests on a perimeter rim that covers the countertop cut edge, keeping laminate and tile edges protected and sealed.
Where This Sink Fits the Work
A sink this size earns its place in a kitchen that handles serious volume. Cooks who regularly tackle whole-bird roasting, large-batch canning, or meal prep for a crowd will recognize the difference a single uninterrupted bowl makes compared to a divided layout. There is no center divider to work around when you are cleaning a stock pot or rinsing a full sheet pan flat on the basin floor.
The top mount installation path makes this sink a practical choice for kitchen renovations where the existing countertop stays in place. Because the rim sits on top of the surface and clips secure the sink from below, the cutout edge does not need to be finished to the same standard as an undermount install. That matters on laminate, tile, and post-form counters where an exposed edge would be a liability.
Quartz Composite in Black: Material and Durability
Quartz composite is an engineered material, not a natural stone, and its behavior in a kitchen reflects that. The 80% quartz content makes the bowl highly resistant to the abrasions that dull stainless steel over time. The acrylic resin binder gives the material a degree of flexibility that fired ceramics lack, which is why quartz composite handles an accidental dropped pan better than fireclay. Heat resistance is strong for normal kitchen use, though sustained direct contact with a boiling pot bottom is better avoided on any composite bowl.
The Black color runs through the full thickness of the material rather than sitting as a surface coating. Everyday scuffs and the minor surface marks that come with a working kitchen remain far less visible against a consistent dark base than they would on a lighter color or a thin-finished surface.
The Right Buyer for This Sink
This sink fits kitchen remodels, new builds, and cabinet shop display kitchens where a large, dark-toned basin makes a design statement without requiring the countertop to be rebuilt around it. Homeowners upgrading a laminate kitchen, designers specifying for a rental property, and contractors outfitting a spec home all benefit from the top mount path: it requires no special countertop edge profile, no seamless bonding steps, and no custom templating beyond the standard cutout.
For cabinet shops and contractors sourcing in volume, the Black quartz composite color holds up in high-traffic settings and resists the showing of water spots and minor marks that can make lighter sinks look tired in a busy space.
Frequently Asked Questions
Does this sink require a special countertop material?
No. The top mount installation is compatible with laminate, solid surface, quartz, stone, and tile countertops. The perimeter rim rests on the surface and the sink clips hold it from below, so the countertop edge does not need a special profile or finish.
Does this sink include mounting clips, a drain, or a grid?
Confirm included components against the spec sheet for this SKU. Drains, grids, and strainers are typically sold separately for QT Series models; a compatible basket strainer and bottom grid should be ordered alongside this sink if needed.
Where does the faucet mount on this sink?
The faucet mounts through the countertop behind the sink rather than through a faucet deck on the sink itself. Plan your faucet hole placement during the countertop cutout stage.
How does the Black color hold up over time?
The Black runs through the full depth of the quartz composite material, not just the surface. Minor scuffs do not expose a contrasting layer beneath, and the dark tone keeps everyday water marks and light scratches less visible than lighter-colored bowls.
Is quartz composite harder to clean than stainless steel?
Quartz composite is non-porous and cleans easily with mild soap and water. Unlike brushed stainless, it does not show directional scratch patterns, and it resists common kitchen stains well. Avoid abrasive scouring pads, which can dull any composite surface over time.
A Single Bowl That Keeps Kitchen Work Moving
The QT-722 in Black gives any kitchen a large, durable wash station that installs cleanly across the widest range of countertop materials. When uninterrupted bowl space and a top mount fit matter, this is a dependable choice.
