A 34-Inch Top Mount Sink For Kitchens That Work Hard
The Karran QT-722 is an extra-large single bowl quartz composite kitchen sink in Concrete finish, designed for top mount installation in virtually any countertop material. Its uninterrupted 34-inch basin gives you the kind of unobstructed workspace that a divided bowl simply cannot match — room for sheet pans, large stockpots, and everything else a busy kitchen demands.
Key Features
• Quartz composite construction — the bowl is made from 80% natural quartz crystals and 20% high-performance acrylic resin, making it highly resistant to scratches, stains, chips, and heat.
• Extra-large single bowl — the uninterrupted basin handles oversized cookware and sheet pans without a center divider getting in the way.
• Top mount installation — drops into a standard countertop cutout from above, with the rim resting on the surface; compatible with laminate, solid surface, stone, and other countertop materials.
• Concrete finish — a muted, warm gray tone that coordinates with both contemporary and transitional kitchen palettes.
• 9-inch bowl depth — deep enough to contain splashing and submerge tall pots without bending over the counter.
Where a Single, Open Basin Makes the Difference
Divided bowls split your workspace in two. A sink this wide with no center divider lets you lay a full sheet pan flat, fill a tall stockpot without tilting it sideways, or soak a cutting board without contorting around anything. It is the configuration that home cooks who batch-prep meals, bakers who clean large pans, and households without a dishwasher reach for first. The 9-inch depth adds to that utility — water stays contained, tall items stand upright, and cleanup moves faster.
Quartz Composite Built for Daily Use
At 80% natural quartz and 20% acrylic resin, this material handles the daily abuse of a primary sink better than many alternatives. Hot pans set down without caution, acidic foods spilled and wiped away, steel utensils clinking the bowl — quartz composite shrugs off all of it at the resistance level the material is known for. The Concrete colorway runs throughout the material, so minor abrasions do not expose a contrasting substrate. The muted gray tone also hides water spots and mineral deposits better than white or black finishes tend to, which matters in areas with hard water.
Right for Renovators, Designers, and Production Shops
Top mount installation is the practical choice whenever a seamless undermount install is not the priority or the countertop material is not suitable for it. The QT-722 drops into a new cutout or replaces an existing same-size opening with straightforward clip fastening from below — no adhesive bonding process, no countertop-material restrictions. That makes it a sound specification for a contractor handling multiple kitchen installs, a designer working with a laminate countertop package, or a homeowner handling their own renovation. Cabinet shops building sink bases can also specify this sink with confidence that the top mount path keeps installation simple for whoever handles the final fit-out.
Is a template or mounting clips included with the QT-722?
This sink is a top mount model; it drops into a countertop cutout from above rather than requiring the clip-and-adhesive process of an undermount. Check your specific SKU packaging or contact our team to confirm what hardware ships with the unit, as inclusion varies.
Can this sink be installed in a laminate countertop?
Yes. The top mount installation method places the rim on top of the counter surface, covering the cut edge — making it fully compatible with laminate. The rim protects the exposed edge of the cutout, which is one of the reasons drop-in sinks remain a preferred choice for laminate installations.
What drain opening does the QT-722 use?
Kitchen bowls in this Karran series typically use a 3-1/2 inch drain opening. Confirm the drain opening from the spec sheet for this model before ordering a basket strainer separately, as the drain assembly is not included.
How does the Concrete finish hold up against staining?
The quartz composite material is highly stain resistant. The Concrete colorway's mid-tone gray also tends to camouflage water spots and mineral deposits that show more readily on white or very dark finishes. For best results, dry the bowl after use and avoid abrasive cleaners.
A Sink Sized for How You Actually Cook
The QT-722 in Concrete delivers the open workspace of a large single bowl with the installation flexibility of a top mount design — a practical combination for kitchens where the work never really stops.
