Karran QU-711-GR Undermount Sink For New Tops

Karran QU-711-GR undermount sink is a 32-1/2 inch wide by 19-1/2 inch deep quartz gray double 60/40 bowl unit that provides a large and a smaller bowl, giving installers and users two work zones in the same cutout. The external bowl dimensions of 32-1/2 inches by 19-1/2 inches define the footprint, which helps plan cabinet sizing and countertop layout before cutting. Internal bowl dimensions of 17-1/2 inches by 15-3/4 inches by 9 inches and 11-3/8 inches by 15-3/4 inches by 9 inches show the relative capacities, allowing the larger side to handle bigger pots while the smaller side is suited to secondary tasks. The sink bowl surface has a matte finish, which produces a softer visual appearance in the kitchen and reduces reflected glare around work lighting. All external dimensions are approximate to 1/4 inch, providing a clear tolerance range when planning the cutout and positioning in new countertops.

Quartz Double Bowl Details That Support Workflow

• The manufactured composition of 80 percent crushed quartz plus 20 percent acrylic resin creates a quartz sink structure, offering a dense, engineered material that suits everyday kitchen use where impact and temperature changes are common.
• The 1-1/4 inch by 3/4 inch machined resin matrix rim gives a defined, consistent edge, helping installers align the sink accurately under the countertop and achieve a clean reveal along the perimeter.
• The double 60/40 bowl layout with one larger and one smaller bowl organizes tasks, letting one side handle washing or rinsing while the other is available for separate prep or soaking work.
• The 3-1/2 inch waste opening matches a standard-sized drain fitting, which streamlines drain selection and helps tie the sink into typical residential plumbing arrangements without unusual transitions.
• The quartz gray color in a matte finish presents a neutral, low-sheen surface, helping the sink visually coordinate with a range of stone countertop colors while avoiding a highly reflective look around fixtures.

Undermount Installation And Countertop Planning

This Karran quartz kitchen sink is designed for undermount installation, so it is fastened beneath the countertop and leaves the deck surface uninterrupted around the bowls. It may not be top mounted, which concentrates planning around an under-counter support method and an accurate cutout. The sink can only be installed in new countertops and not in existing countertops with an existing sink cutout, focusing the product on new fabrication work rather than retrofit situations. This sink may be undermounted to all stone products, opening it to use with a range of stone-based tops in a fabrication shop. An 1/8 inch overhang is recommended, but it can also be flush installed, giving fabricators a choice between a slightly recessed reveal or a level edge to match customer preference.

Using This Quartz Sink In Real Install Projects

Where This Quartz Gray Double Bowl Sink Fits

This Karran 32 inch by 19-1/2 inch quartz gray double 60/40 bowl undermount sink works in kitchens built around new countertops, since it can only be installed in new countertops and not into tops with existing cutouts. The external dimensions define the space it occupies in stone, so fabricators can align it with cabinet framing and clearances under the deck. Internal bowl dimensions of 17-1/2 inches by 15-3/4 inches by 9 inches and 11-3/8 inches by 15-3/4 inches by 9 inches give one deeper washing area and a second full-depth bowl, which supports typical kitchen cleaning and prep patterns. This sink may be undermounted to all stone products, so stone shops can use the same model across different stone materials while keeping a consistent bowl layout in their projects.

Details That Help Fabricators Deliver Consistent Results

The composition of 80 percent crushed quartz plus 20 percent acrylic resin forms a stable quartz sink body, which helps it partner with stone countertops in terms of feel and performance. The 1-1/4 inch by 3/4 inch machined resin matrix rim provides a precise bearing surface under the countertop, supporting accurate placement and a uniform reveal along all sides. A 3-1/2 inch waste opening lines up with standard drain components, which simplifies routing the opening in the stone and connecting to plumbing without special adapters. The sink bowl surface has a matte finish, so installers can blend it with honed or low-sheen stone surfaces in design-driven kitchens. All external dimensions are approximate to 1/4 inch, giving a practical tolerance when programming cut files or setting up manual templates in the shop. Digital templates for CNC machines are available at www.karran.com, which helps CNC-equipped shops integrate this model into automated fabrication workflows with repeatable cutout geometry.
