The Karran QT-811-CN-PK1 is a 33-inch quartz double-bowl drop-in kitchen sink in a Concrete finish, designed to top-mount into any countertop material with a 60/40 bowl split that gives a larger primary basin alongside a compact secondary bowl.
The 60/40 split gives the larger left bowl enough room to handle a full load of dishes, a sheet pan, or a stockpot, while the right bowl stays ready for rinsing produce, draining pasta, or keeping a workspace clear. That division matters on a busy prep day when both sides of the sink are in use at once. The Concrete finish adds a visual anchor that reads as a design choice rather than a default, making the sink a surface that holds its own against natural stone countertops and matte cabinet finishes.
Karran's quartz composite construction gives the sink its dense, stone-like feel and the Concrete finish its depth of color. The material is consistent through the bowl rather than a surface coating, so chips and scratches that reach the body stay the same color. Both bowls share a 9-inch inside depth, giving genuine room for larger cookware without shallowing out toward the rim. Because this is a top-mount design, the sink rim sits on top of the countertop surface, making it a straightforward fit for a wide range of countertop types without the specialized fabrication that an undermount installation requires.
This sink is a practical choice for a kitchen remodel or new build where the countertop is laminate, solid surface, tile, butcher block, or stone, and a standard drop-in install is the right path. Homeowners upgrading from a stainless or acrylic sink will find the quartz composite adds weight and a quieter sound at the basin. Designers specifying a kitchen with a concrete or industrial aesthetic can use the Concrete finish to carry that palette through to the sink itself. Cabinet shops and contractors will appreciate that the top-mount method works across countertop materials without custom cutout coordination, and that the cUPC and IAPMO certifications satisfy standard plumbing inspections. The minimum cabinet width is 33 inches, matching the overall sink length, so measure the base cabinet before ordering.
Yes. Because it is a top-mount sink, it drops into a standard countertop cutout from above and rests on the rim, so it can work in an existing countertop as long as the cutout dimensions match and the cabinet is at least 33 inches wide.
It is designed for installation into all countertop materials, including laminate, solid surface, granite, quartz slab, tile, and wood.
The left bowl is the larger 60 percent basin, measuring 17-1/8 inches long by 19 inches wide and 9 inches deep. The right bowl is the smaller 40 percent basin at 11-1/2 inches long by 16-3/4 inches wide and 9 inches deep.
No. This sink is not ADA compliant.
The sink is cUPC and IAPMO certified, meeting North American plumbing code standards.
For a drop-in kitchen sink that brings an industrial, concrete-inspired finish to any countertop material, the Karran QT-811 in Concrete delivers a double-bowl layout and certified quartz construction that holds up to daily kitchen work.
