A Compact Single Bowl Sink Built for Workspaces Where Every Inch Counts
The Karran Profile PU57 is a 16-gauge stainless steel undermount kitchen sink with a single bowl in a 23 by 17-3/4 by 8-3/4 inch footprint. It mounts beneath the counter for a clean, unobstructed surface and fits cabinet runs where a larger double-bowl sink simply won't land.
Key Features
• 16-gauge stainless steel construction delivers a thicker, more rigid bowl than standard 18-gauge models.
• Single bowl layout gives uninterrupted interior space for washing full-size pots and pans without a center divider in the way.
• Undermount installation positions the bowl beneath the countertop so the counter surface wipes clean all the way to the edge.
• Compact 23-inch footprint fits smaller sink base cabinets while still offering nearly 9 inches of bowl depth.
• Profile Series build quality brings a brushed satin finish and tight manufacturing tolerances to an accessible price point.
Where This Sink Fits the Job
A 23-inch single-bowl sink covers the jobs that matter most at a secondary station: rinsing produce, filling stockpots, and keeping prep work moving without bouncing back to the main sink. In a galley kitchen or a smaller apartment layout, it also steps up as a capable primary sink, because the open single bowl handles large cookware that a divided double bowl cannot. Island builds and butler's pantries benefit from the compact width while still getting nearly 9 inches of working depth, which is more than enough for deep mixing bowls and tall cooking vessels. Contractors fitting out smaller kitchens or refreshing a dated undermount position will find the 23-inch format covers the common sink base sizes without a custom cabinet order.
Construction and Finish
The PU57 belongs to Karran's Profile Series, and the PU5x line within it is built to 16-gauge steel, a meaningful step up in wall thickness over the 18-gauge sinks common at this size. Thicker gauge reduces flex and vibration when the bowl fills or drains, and it holds its shape over years of daily use. The exterior carries a brushed satin finish that blends with most stainless faucets and hardware without requiring an exact finish match. Because the bowl mounts below the counter, the faucet and any accessories will mount through the countertop behind or beside the bowl rather than through a sink deck.
Who Reaches for This Sink
Designers specifying a smaller kitchen or a secondary prep zone get a clean, undermount profile that disappears into the countertop and focuses attention on the surface material. Cabinet shops outfitting production kitchens appreciate that 16-gauge construction holds up to the daily wear that lighter sinks show quickly. Homeowners replacing an older undermount in a compact base cabinet get a straightforward swap that upgrades the gauge without requiring a cabinet change. The single bowl format is also a deliberate choice for anyone who hand-washes oversized cookware and has no use for a center divider taking up bowl real estate.
Will this sink work with my existing countertop cutout?
That depends on your current cutout dimensions. The PU57's overall size is 23 by 17-3/4 inches. An existing cutout built for a sink of similar overall dimensions is often reusable, but the actual sink should be on hand and compared against the opening before cutting or committing to an adhesive bond. Confirm your cabinet's minimum interior width supports the sink before ordering.
Does the sink include a drain or mounting hardware?
Drain components and installation hardware are sold separately for this SKU. You will need to source a kitchen basket strainer sized for a standard 3-1/2 inch drain opening, plus the clips or adhesive appropriate for your countertop material and installation method.
Why does gauge matter for a sink this size?
In a compact bowl, flex and noise are more noticeable because the bowl walls are closer together. At 16 gauge, the PU57's walls are thicker than an 18-gauge counterpart, which reduces the drum-like resonance when water hits the bowl and keeps the sink feeling solid underhand. For a sink that sees daily use, the heavier gauge is a worthwhile difference.
Is this sink suitable for a laminate countertop?
The PU57 is a conventional undermount sink, not a seamless-rim model. Undermount installation is standard in stone, quartz, and solid surface countertops. For laminate, look at Karran's Edge Series, which is designed and documented for seamless laminate integration.
Compact Footprint, No Compromise on Depth
The PU57 proves that a smaller sink base doesn't mean sacrificing working depth or build quality. At 16-gauge construction with nearly 9 inches of bowl depth in a 23-inch frame, it handles the full workload of a primary or secondary station while fitting where a larger sink cannot.
