Extra-Large Bowl, Matte Black Finish, All-Countertop Fit
The Karran QT-722 is a quartz composite top mount kitchen sink built around an uninterrupted extra-large single bowl, finished in Black. Where a divided bowl would get in the way of sheet pans, oversized stock pots, or commercial cutting boards, the QT-722 delivers open, unobstructed workspace in a drop-in format that installs in virtually any countertop material.
Key Features
• Extra-large single bowl provides an uninterrupted basin well suited to washing large cookware and bulky items without a center divider in the way.
• Top mount installation drops into a countertop cutout from above and is compatible with laminate, wood, stone, solid surface, and quartz countertops.
• Quartz composite construction combines 80% natural quartz crystals with 20% high-performance acrylic resin for a highly scratch, stain, chip, and heat resistant surface.
• Matte Black finish is an integral part of the quartz composite material, not a surface coating, so color runs through the bowl and resists fading.
• 9-inch bowl depth accommodates tall pots and deep mixing bowls without splashing water onto the counter.
Where an Uninterrupted Basin Changes the Workflow
A single-bowl sink in an extra-large footprint makes the most sense in kitchens where hand-washing is the rule rather than the exception. Sheet pans lay flat. Half hotel pans submerge fully. A large cast-iron skillet has room to soak without crowding the drain. Cabinet shops and woodworking studios that include a kitchen or break room prep sink find the same benefit: one generous basin handles cleanup tasks that a divided bowl would split awkwardly. At 34 by 22 inches, the QT-722 fits a 36-inch sink base cabinet, the standard size in most residential and light commercial kitchen runs.
Material Built for Daily Contact
Quartz composite is a durable choice for a primary kitchen sink. The 80% quartz content gives the bowl hardness and resistance to the chips and scratches that come with regular cookware contact. The acrylic resin binder ties the quartz together into a non-porous surface that does not harbor bacteria in the way a porous material might, and it holds up to the heat of drained pasta water or a rinsed cast-iron pan fresh from the stove. The Black finish on the QT-722 is true throughout the composite body, so a chip or scratch does not reveal a different color underneath. The matte surface tends to show water spots less than a polished finish, which matters in kitchens where towel-drying every drop is not practical.
A Good Match for Renovation and New-Build Kitchens Alike
Top mount installation makes the QT-722 a realistic choice across a wider range of projects than an undermount sink. It installs into existing countertops without exposing a finished edge, making it well suited to laminate renovations or retrofits where the countertop is staying in place. For new builds, the drop-in format works with stone, solid surface, and engineered quartz as well. Designers specifying a contemporary kitchen with Black hardware and fixtures will find the QT-722 coordinates naturally with matte black faucets, pulls, and appliance trim. Cabinet shops building and delivering complete kitchens can drop it in at the shop or on site without specialized fabrication tools.
Frequently Asked Questions
Does the Black finish show water spots or mineral deposits?
A matte black quartz composite surface tends to show water spots less than a polished or gloss finish. In hard-water areas, wiping the bowl dry after use will minimize mineral buildup. The integral color means any minor surface abrasion does not reveal a contrasting base color underneath.
What countertop materials work with a top mount installation?
Top mount sinks install from above, with the rim resting on the countertop surface and sealed with silicone. That installation method is compatible with laminate, wood, stone, solid surface, and engineered quartz countertops because the rim covers the cut edge and no special edge finishing is needed.
Is a template included with the sink?
Karran QT Series spec documentation does not confirm a template is included in the box. For an accurate cutout, set the physical sink on the countertop and trace the rim perimeter directly, or download a DXF file from the manufacturer for CNC cutting.
Where does the faucet mount on a QT-722?
The QT-722 is a top mount sink. Faucet holes are drilled in the countertop behind the sink rather than in a faucet deck on the sink itself. Check the specific faucet's deck-thickness requirements against your countertop before ordering.
Can this sink be used with a garbage disposal?
A single-bowl sink with one drain opening typically pairs with a disposal by replacing the standard basket strainer with a disposal flange. Confirm the disposal flange fits the drain opening of the QT-722 before installation.
One Basin, Built to Handle Whatever Comes Next
The QT-722 pairs a basin large enough for serious kitchen work with a durable quartz composite body and a matte Black finish that holds up to daily use without demanding constant attention. For kitchens where workspace at the sink matters as much as the sink's appearance, this is a straightforward choice.
