The Karran QT-721 is a 34-inch wide quartz double-bowl kitchen sink in a Concrete finish that installs from above into any countertop material, making it a direct fit for remodels and new builds alike.
A 60/40 split means the larger left bowl handles the heavy lifting, pots, pans, and soaking, while the right bowl stays ready for rinsing produce or holding a colander. Top-mount installation means the sink rim sits on the countertop surface and the countertop material carries the sink's perimeter. Because the install works with any countertop material, this sink fits wherever a standard drop-in cutout can be made, without special fabrication or bonding requirements.
Quartz composite sinks bring the visual weight of concrete and stone without the maintenance demands. The Concrete finish on this sink reads as a cool, textured grey that coordinates naturally with matte tile, dark cabinetry, stainless appliances, or raw wood counters. The surface is non-porous by nature, which means stains and food residue do not absorb the way they would in a poured or polished stone surface. Both bowls share a 9-inch depth, giving the sink a proportional profile that suits a workhorse kitchen setup.
This sink works best in kitchens where the countertop material or budget rules out an undermount install, or where a remodel is updating the sink without replacing the entire counter. A laminate kitchen that wants the look of a stone or concrete basin, a rental kitchen being upgraded on a budget, or a new build running standard laminate or butcher block counters are all natural fits. The 34 by 22-inch footprint and the 36-inch minimum cabinet requirement are the key numbers to run against the existing cabinet layout before ordering.
Yes. Because it is a top-mount sink, it rests on the countertop rim and installs into any countertop material, including laminate. No special bonding or fabrication is required.
The left bowl is the larger of the two, at 18 inches inside length and 18 inches inside width. The right bowl measures 11-1/2 inches inside length and 16-1/2 inches inside width.
No. This sink is not ADA compliant.
It is cUPC and IAPMO certified for residential and commercial plumbing use.
This sink brings a concrete-textured quartz finish and a practical 60/40 split into a top-mount package that drops into any counter, making it the straightforward choice when an undermount is not on the table.
