The Karran 31-3/8" Undermount Large Single Bowl Quartz Composite Workstation Kitchen Sink Kit in Black is designed for installation in granite, quartz, and solid surface countertops. Made from an 80% quartz and granite composite blended with 20% acrylic resin, it brings the look and feel of natural stone together with a 1/2" positive reveal ledge built for workstation accessories. The refined matte surface is heat resistant up to 535°F, and the dense composite naturally absorbs vibration to quiet running water and dishwashing noise. The kit includes a flush-fit acacia wood cutting board, a roll-up drying rack, and a black basket strainer, so this black quartz workstation sink is ready to prep, wash, and dry from the day it is installed.

Workstation Ledge Design: Prep, Rinse, and Dry in One Place

The 1/2" positive reveal along the rim of this black undermount quartz workstation sink creates a dedicated ledge for accessories, so the included acacia wood cutting board sits flush and level with the countertop for a more integrated look and effortless cutting. That flush fit keeps the board stable during use rather than teetering on an uneven edge, and it extends the usable prep surface directly over the bowl. The 29" x 16-3/8" x 9" bowl has no center divide, giving you one large, open basin for washing oversized pots, sheet pans, and roasting trays without tilting, stacking, or splashback. Rounded corners throughout the bowl wipe clean easily, with no tight seams for food residue to collect.

An undermount installation lets the countertop run uninterrupted to the edge of the cutout, with no rim or lip resting on top of the material, so crumbs and spills sweep straight into the bowl. The reversible offset drain lets you choose the drain location at installation, moving the plumbing to whichever side of the cabinet suits your layout and leaving more usable storage space below the sink. The included roll-up drying rack supports up to 40 lbs, is dishwasher safe, and rolls up for compact storage when the counter needs the room. A sink-matched basket strainer catches food debris to help keep the drain clear, and its color coordinates with the sink for a finished look.

Matte Black: A Definitive Finish for Contemporary and Transitional Kitchens

Matte black makes a deliberate statement at the countertop, grounding the kitchen with depth and contrast without the reflectivity of polished surfaces. It pairs naturally with brushed nickel, gunmetal, and matte black hardware for a fully resolved palette, and holds its own alongside bold stone choices like dark marble, slate, or dramatically veined quartz. In lighter kitchens built around white or light grey cabinetry, it anchors the space with a strong material moment. Against darker cabinetry in charcoal, navy, or deep forest green, it gives a unified finish that lets the overall design carry.

Quartz Composite Performance: Durable, Sound-Absorbent, and Low-Maintenance

Built from an 80% quartz and granite composite blended with 20% acrylic resin, this black quartz kitchen sink delivers a dense, non-porous surface that resists staining, scratching, abrasion, and impact through years of demanding use. The color is integrated into the material rather than painted on, so it stays consistent across the entire basin. Rated heat resistant up to 535°F, the surface handles hot cookware set directly in the bowl without damage. Sealing is not required, and routine cleaning with mild soap and water keeps the matte finish in excellent condition. The same dense composite naturally absorbs vibration and sound, dampening the noise of running water and cookware for a quieter kitchen.

Specifications and What’s Included

This black quartz workstation sink measures 31-3/8" x 18-7/8" x 9-1/2" overall, with a 29" x 16-3/8" x 9" bowl and a 3-3/4" drain, and it requires a minimum 36" cabinet. A cutout template and digital DXF file are included so the sink cutout is specific to this workstation installation, along with mounting clips for a secure undermount fit. The kit includes a black basket strainer, an acacia wood cutting board, and a roll-up drying rack, giving you everything needed to use the ledge on day one.
