The Karran QTWS-875-GR is a single-bowl top mount workstation sink in a gray quartz finish, sized at 33 inches wide by 22 inches deep and designed to drop into any countertop material for a straightforward, versatile install.
A workstation sink adds a built-in ledge around the bowl perimeter so a cutting board, colander, or drying rack can sit above the basin and slide from one side to the other. That ledge turns the sink from a washing station into an active prep zone, keeping the countertop clear while food moves from cutting to rinsing to draining without leaving the sink area. The 9-inch bowl depth is deep enough to handle tall pots and large roasting pans without splashing over the sides.
The gray finish reads as a neutral that pairs with white, black, and warm-toned cabinets without locking the kitchen into a single palette. Quartz composite is dense and non-reflective at this color depth, which means the matte gray surface keeps water spots and minor scuffs from standing out the way they would on a polished finish. Top mount installation seats the sink rim on top of the countertop, which means it fits any solid surface without special fabrication. Laminate, granite, quartz, butcher block, concrete, and tile all work.
This sink is a practical choice for a main kitchen where one large basin handles the bulk of dishwashing, soaking, and prep rinsing, and where the workstation ledge fills in for limited counter space. It also suits a kitchen remodel where the countertop is being kept and a top mount drop-in is the only viable install path. The 33-inch width requires a minimum 33-inch cabinet opening, so confirm the base cabinet width before ordering. Because it top mounts into all countertop types, it works equally well in a laminate kitchen and a stone countertop installation, without requiring a fabricator to cut an undermount-specific edge profile.
Yes. Top mount sinks drop into a cutout from above and rest on the counter surface, so this one works in both new countertops and existing countertops with an appropriately sized cutout.
It is designed for installation into all countertop materials, including laminate, quartz, granite, solid surface, and tile.
The ledge is designed to accept coordinating workstation accessories such as cutting boards, colanders, and drying racks. Confirm accessory compatibility with the QTWS-875 series before ordering separately.
No. This sink is not ADA compliant. It is cUPC certified for standard residential and commercial plumbing code compliance in the US and Canada.
Choose the QTWS-875-GR when the goal is a gray quartz kitchen sink that installs without countertop restrictions, gives the cook a full 9-inch-deep bowl to work in, and puts a prep-ready ledge to use above the basin every day.
