16 Gauge Stainless Precision Built For Tight Spaces and Secondary Stations
The Karran Select Series SU71 is a 16 gauge stainless steel single bowl undermount sink sized to deliver professional-grade durability in compact installations. At 16-1/2 by 18 by 9 inches, it fits where a full-size bowl cannot, without giving up the construction quality that makes a sink last.
Key Features
• 16 gauge stainless steel construction delivers a noticeably thicker, more rigid bowl than standard 18 gauge sinks in the same footprint.
• Single bowl undermount design mounts beneath the countertop for a clean, wipe-friendly edge at the countertop surface.
• Tight-radius corners give the interior a squared, contemporary profile that suits modern cabinetry.
• Compact 16-1/2 by 18 inch footprint fits island and secondary sink bases where a 33 inch double bowl would not.
• 9 inch bowl depth handles pots and prep work without the sink dominating the cabinet run.
Where This Sink Earns Its Place
Secondary sink stations are where this bowl makes the most sense. An island prep area, a butler's pantry, or a small wet bar all benefit from a sink with real construction behind it rather than a lightweight budget bowl. The compact footprint also works well in smaller primary kitchens where counter space is limited and a single bowl is the practical choice. Fabricators and cabinet shops specifying sinks for residential builds and renovation jobs will find the 16-1/2 by 18 inch size fills a gap that neither a standard bar sink nor a full 30 inch bowl addresses cleanly.
Construction and Material
The Select Series designation is the key signal here. The SU-series carries 16 gauge steel, which is thicker than the 18 gauge used in most contractor-grade stainless sinks at this price point. Thicker steel deadens sound better, resists flexing under load, and holds up longer in daily use. The tight-radius corner geometry is a Select Series detail that sets the bowl apart visually from rounder economy bowls, and it matches well with the flat-front and shaker cabinet styles common in current kitchen design. The undermount installation keeps the counter surface continuous, making cleanup straightforward and the overall look intentional rather than incidental.
Who This Is For
Cabinet shops outfitting kitchen islands will appreciate the size and gauge combination. Designers specifying a secondary sink for a high-use household kitchen can recommend this bowl with confidence that the material backs up the look. Homeowners renovating a smaller galley kitchen who want a single-bowl undermount with above-average construction rather than a builder-grade alternative will find the Select Series gives them a step up without moving into a specialty price tier. This sink suits indoor residential installations in granite, quartz, and solid surface countertops where the countertop fabricator will handle the undermount attachment method.
Frequently Asked Questions
Does this sink install seamlessly in laminate countertops?
No. The SU71 is a standard undermount sink, not a seamless series model. Karran's seamless laminate and solid surface capability belongs to the Q Series quartz and Edge stainless E Series lines. This sink is designed for undermount installation in granite, quartz, and solid surface countertops.
What is the difference between 16 gauge and 18 gauge, and does it matter for a small sink?
Lower gauge numbers mean thicker steel. A 16 gauge bowl is meaningfully stiffer and quieter than 18 gauge, and it matters in a compact sink just as much as in a large one. A smaller bowl flexes more easily than a large one if the steel is thin, so the heavier gauge is a real benefit even at this size.
Are grids, strainers, or a drain assembly included?
The SU71 is a bare sink. Grids, basket strainers, and drain assemblies are sold separately. Confirm accessory compatibility at the model level before ordering, since grids are sized to specific bowls.
What minimum cabinet size does this sink require?
At 16-1/2 by 18 inches overall, this sink fits compact sink base cabinets. Verify the actual sink dimensions against your cabinet opening and confirm the installation method with your countertop fabricator before cutting.
Is this sink appropriate for a bar or prep station rather than a primary kitchen?
Yes. The compact single bowl is a natural fit for island prep areas, butler's pantries, and wet bars. The 16 gauge build means it holds up in active-use environments, not just low-traffic secondary spots.
A Compact Bowl Built to Last
The SU71 delivers Select Series quality in a size that goes where full-scale sinks cannot. Heavier gauge steel, tight-radius corners, and a clean undermount profile make it a specification-worthy choice for secondary stations and compact kitchens alike.
