The Karran Profile PU57 is a single-bowl undermount kitchen sink in stainless steel, made from 16-gauge steel and sized to fit a 27-inch or wider base cabinet. It mounts beneath quartz, granite, or solid surface countertops and carries cUPC certification.
A single-bowl sink clears up the workflow constraints that come with a divided basin. At 8-3/4 inches deep and 21 inches long inside, this bowl handles stockpots, sheet pans, and large cutting boards without needing to angle them around a divider. The 15-3/4-inch interior width keeps the basin practical for daily washing without eating into the counter footprint more than necessary. For kitchens where the sink sees constant use, the uninterrupted bowl is usually the more functional choice.
Gauge matters in a stainless kitchen sink. At 16 gauge, the steel is meaningfully thicker than the 18-gauge material found in many residential sinks, which translates to a stiffer bowl that resists flexing and deadens sound better under running water. The stainless steel finish here is the standard for the Profile series: consistent, easy to clean, and a neutral match against most countertop materials. Because the sink is an undermount, the countertop surface runs directly to the bowl edge with no rim above the counter to collect water or debris, which makes wiping down the counter quick and keeps the install looking clean.
This is a practical choice for a primary kitchen sink in a new build or a full kitchen remodel where the countertop is being fabricated from granite, quartz, or solid surface. The undermount installation method requires a countertop material that can support the sink from below, so it is not suited for laminate or tile-over-plywood counters. At 23-1/4 inches wide overall, it fits comfortably in a 27-inch base cabinet and leaves room in wider cabinets for a single-hole faucet deck or accessory placement. Cabinet shops, designers specifying kitchen packages, and homeowners planning a full counter replacement will all find this a straightforward selection for a hardworking, single-bowl stainless kitchen sink.
It is designed for undermount installation into granite, quartz, and solid surface countertops. It is not intended for laminate or other countertop types that cannot support an undermount sink.
The sink requires a minimum 27-inch wide base cabinet. The overall sink dimensions are 23-1/4 inches side to side and 17-3/4 inches front to back.
