The Karran WS-90-PK1 is a 45-inch single-bowl undermount kitchen sink in 16-gauge stainless steel, built for kitchens where one large, uninterrupted basin is the right tool for the job.
A single-bowl sink this wide gives a full, unbroken work surface inside the basin, which matters when you are bathing a large roasting pan, filling a stockpot, or running a busy prep station. There are no dividers to work around, no split bowls competing for space. The 10-inch interior depth keeps water contained and gives room to submerge deep cookware without the rim getting in the way. The Workstation Series designation means this sink is built to accept compatible workstation accessories, such as colanders, cutting boards, and grids, that sit on the sink ledge and turn the basin into an organized prep zone.
At 16 gauge, this is a thicker-than-standard stainless steel sink body. The material gives the sink a solid, stable feel and holds up to heavy daily use better than lighter-gauge alternatives. The stainless finish reads as a clean, professional surface that pairs well with a wide range of kitchen styles, from industrial to transitional to contemporary. The undermount installation removes the visible rim from the countertop surface, so the counter and bowl read as one continuous plane and cleanup is straightforward.
This sink is a natural fit for a large kitchen island, an extended run of countertop, or any kitchen where the sink is the visual and functional center of the workspace. At 45 inches wide with a 48-inch minimum cabinet requirement, it fills a cabinet run that a standard 30- or 33-inch sink would leave underused. It is well suited to remodels and new builds where the countertop is being fabricated in granite, quartz, or solid surface, since those materials support the undermount install. Designers specifying a statement kitchen sink and contractors outfitting a high-use residential or light commercial kitchen will find the combination of gauge, depth, and basin width covers most demanding scenarios.
A minimum 48-inch cabinet width is required. The sink's overall width is 45 inches, so the cabinet must be sized to accommodate it.
This sink is designed to undermount into granite, quartz, and solid surface countertops. Confirm with your countertop fabricator that the material and edge profile are suitable for an undermount application before finalizing the order.
Workstation Series sinks are built to accept compatible accessories, such as cutting boards, colanders, and basin grids, that rest on the sink ledge. Accessories are sold separately; check the compatible Karran workstation accessory SKUs for this model.
