Karran Profile stainless steel undermount sink describes a 23-1/4 inch wide, single bowl, 16 gauge stainless steel kitchen sink designed for undermounting. This configuration creates a clean, drop-free transition at the countertop edge, which matters when you want a smooth wipe-down surface around the sink opening. The sink is used for undermounting in granite, quartz, and solid surface countertops, so it aligns well with typical residential and light commercial kitchen projects using these materials. The stainless steel construction provides a familiar working material for installers, which simplifies alignment and support methods during the undermount process. All external dimensions are approximate to 1/4 inch, so the sink size allows normal cutout planning tolerances in a countertop shop environment where templates and CNC programming need a reasonable margin.
The Karran Profile 23-1/4 inch wide single bowl undermount sink defines its role at the underside of granite, quartz, and solid surface countertops, which guides how fabricators route and polish cutouts. The single bowl format concentrates the weight and support points, which matters when planning sink rails, front-to-back blocking, or bracket locations in the base cabinet. All external dimensions being approximate to 1/4 inch gives countertop shops a clear tolerance band when creating templates, so they can program cutouts that balance reveal preference with safe edge clearance. The 16 gauge stainless steel construction adds rigidity at the mounting flange, supporting stable bond lines with stone or solid surface adhesives during undermount installation.
The Karran PU57 undermount kitchen sink is used in granite, quartz, and solid surface countertop installations, so it fits common upgraded kitchen projects where those tops are already specified. The 23-1/4 inch width lets designers and installers work within typical 27 inch or larger base cabinet scenarios, helping them center the bowl under standard faucet and window locations. As a single bowl stainless steel undermount sink, it becomes a straightforward choice for fabricators who want one consistent cutout and mounting routine across several top materials, reducing variation between jobs. The stainless steel sink classification also aligns with kitchen and bath cabinet projects handled by woodworking shops that already work with sinks as part of full-room packages.
The 16 gauge stainless steel construction gives the PU57 a sturdy rim that sits firmly against the underside of granite, quartz, or solid surface tops, which helps maintain a consistent reveal or flush detail along the cutout edge. All external dimensions being approximate to 1/4 inch allows programmers and template makers to factor that tolerance into CAD drawings, so they can select cutout sizes that accommodate small manufacturing variances while still aiming for a tight, professional undermount appearance. The single bowl format limits the number of corners and transitions in the cutout, simplifying routing and edge finishing steps in the shop. Because the sink is identified as a replacement for old WBSC part number KAPU27N, it also provides a clear path when updating specifications on repeat projects or revising shop drawings that reference the previous code.
The Karran PU57 sink is used for undermounting in granite, quartz, and solid surface countertops, so it suits projects that already specify these rigid surfacing materials.
The Karran Profile undermount sink has a 23-1/4 inch external width, which guides cabinet sizing, cutout layout, and positioning within a typical kitchen base run.
The PU57 sink is made from 16 gauge stainless steel, giving it a thicker, more rigid body that supports a stable undermount bond against stone or solid surface tops.
All external dimensions of this sink are approximate to 1/4 inch, so fabricators can plan cutouts and reveals with that tolerance in their CAD or template process.
The manufacturer part number for this Karran stainless steel undermount kitchen sink is PU57, which helps keep specifications and ordering consistent across projects.
This PU57 sink is listed as a replacement for old WBSC part number KAPU27N, which helps update existing drawings or job files that reference the previous code.
The Karran Profile stainless steel undermount sink gives granite, quartz, and solid surface fabricators a defined 23-1/4 inch wide, single bowl, 16 gauge option that fits well within common base cabinet layouts. The approximate to 1/4 inch external dimensions support predictable templating and CNC programming, while the replacement reference to KAPU27N helps align new orders with existing shop standards. For kitchen and bath projects that already call for stainless steel undermount sinks in rigid tops, choosing the PU57 part number streamlines both specification and repeatable countertop fabrication work.
