Dual-Basin Prep Power And Undermount Polish
The Karran QUWS-880-BL is a quartz composite undermount workstation kitchen sink with two equal 50/50 bowls, an integrated prep ledge, and a complete accessory kit. It mounts beneath the countertop for a clean, rimless surface and delivers a fully equipped prep station right over the bowl in a bold Black finish.
Key Features
• Equal double-bowl layout divides the sink evenly so one side handles washing while the other stays free for rinsing or prep.
• Integrated workstation ledge spans the rim and supports sliding accessories for cutting, draining, and drying directly over the basin.
• Quartz composite construction combines 80% natural quartz crystals with 20% acrylic resin for a surface that is highly scratch, stain, chip, and heat resistant.
• Undermount installation tucks the sink beneath the countertop so the counter edge wipes clean with no rim collecting debris.
• Matte Black finish delivers a bold, on-trend look that holds its color as part of the quartz composite material throughout.
• Included accessory kit provides the cutting board, colander, drying rack, bottom grid, and basket strainer to start working at the ledge immediately.
Built for Two-Station Kitchen Workflows
Equal-bowl workstation sinks fit kitchens where two tasks routinely compete for basin space. The symmetrical 50/50 configuration lets one cook wash produce on the left while a second rinses cookware on the right, or keeps one bowl reserved as a colander station while the other stays clear. The integrated ledge bridges both bowls, so the cutting board or drying rack slides freely to wherever it is needed at the moment. At 9 inches deep, the bowls handle large stockpots and sheet pans without crowding. This is a practical sink for households that cook seriously and want the counter space back.
Quartz Composite From Surface to Core
Because the Black color runs through the quartz composite body rather than sitting as a surface coating, the finish does not chip away to reveal a different substrate underneath. The 80% quartz content makes the material harder and denser than acrylic alone, giving it strong resistance to the daily contact points: knife marks near the cutting board, hot pan bottoms rested on the rim, and concentrated cleaning products. Undermount installation removes the top-mount rim from the equation entirely, leaving a smooth counter-to-bowl transition that is easy to keep clean and reinforces the sink's modern aesthetic.
The Right Fit for Renovation Kitchens and New Builds Alike
Cabinet shops and contractors specifying undermount sinks in solid surface, stone, or quartz countertops will find this model slots naturally into that workflow. The undermount format suits fabricators who are already finishing a countertop edge, and the quartz composite body is compatible with those countertop materials. For homeowners mid-renovation, the Black finish anchors darker design palettes and coordinates cleanly with matte black faucets and hardware. Designers working with two-cook household briefs benefit from specifying the equal-bowl layout rather than an offset configuration, and the included accessory kit means the workstation function ships with the sink rather than requiring a separate sourcing step.
What accessories are included with this sink?
The kit includes a bottom grid, basket strainer, cutting board, colander, and drying rack. These are the accessories stated for the QUWS workstation pack and they ship with the sink.
Does the undermount installation work with laminate countertops?
The QUWS series is a standard undermount sink, not a seamless series. It is designed for solid surface, stone, and quartz countertops where the countertop edge can be finished over the rim. For laminate installations needing a seamless rim, Karran's Q Series is the appropriate choice.
Are the two bowls the same depth?
Yes. Both bowls are equal in size and 9 inches deep, so neither side has a shallower basin that limits what fits in it.
Is a drain or faucet included?
The kit includes basket strainers for both bowls. A faucet and drain assembly are not included and are sold separately. Because this is an undermount sink with no faucet deck, the faucet mounts through the countertop.
How does the Black finish hold up over time?
The color is integral to the quartz composite material, not a surface layer. It resists fading and will not chip away. Normal care with non-abrasive cleaners keeps the surface looking consistent without special coatings or periodic re-sealing.
A Sink That Earns Its Space Every Day
When both bowls are in use and the ledge is holding the cutting board over the basin, the QUWS-880-BL stops being a fixture and starts being a workstation. The Black quartz finish makes it a design statement too, but the equal-bowl layout and the included accessories are what keep the kitchen moving.
