16 Gauge Construction And a Compact Footprint Built for Secondary Stations
The Karran Select Series SU73N is a 16 gauge stainless steel undermount kitchen sink in a compact single bowl configuration, sized to fit smaller sink bases, secondary kitchen stations, and island cutouts where a full-size bowl would be too deep or too wide.
Key Features
• 16 gauge stainless steel delivers noticeably thicker walls and a quieter, more solid feel than standard 18 gauge models.
• Tight-radius corners give the bowl a squared, contemporary interior profile that reads as architectural rather than utilitarian.
• Single bowl configuration provides an uninterrupted basin suited to prep work, hand-washing, and compact wash stations.
• Undermount installation keeps the countertop edge wipe-clean with no exposed rim collecting debris around the bowl perimeter.
• Sold as a box of 40 makes this an efficient source for multi-unit residential projects, kitchen showrooms, and shop stocking.
Where This Sink Fits
A 21-1/4 by 17-1/4 inch footprint puts this bowl into a different conversation than a 30 or 33 inch main kitchen sink. It suits island prep stations where a smaller cutout preserves countertop workspace on either side. It fits butler's pantry cabinets and wet bar runs where the opening is tight and a double bowl would crowd the plumbing below. For multi-unit residential builds, a compact 8-1/4 inch deep single bowl handles day-to-day rinsing without dominating a secondary station. The box quantity of 40 also makes it a natural choice for builders and kitchen dealers stocking across multiple units in a single project.
Material and Build
The Select Series designation within Karran's stainless line carries two consistent construction choices: 16 gauge steel and tight-radius corners. The gauge difference matters most at the bottom of the bowl, where 18 gauge alternatives tend to flex or resonate more under running water. The squared corners are a fabrication decision that matches contemporary cabinet profiles and cabinet door styles. The satin brushed interior finish hides minor watermarks and surface scuffs that show more readily on a polished bowl.
Buyers for This SKU
Cabinet shops fitting out multi-unit projects will recognize the value in a box of 40 of the same SKU: consistent templating, consistent cabinet spec, and one purchase order covering a full run. Kitchen dealers and designers specifying secondary wash stations get a bowl that photographs well alongside modern hardware without the bulk of a primary sink. Contractors sourcing a replacement or upgrade for a compact sink base will find the undermount footprint straightforward to work with on quartz, granite, and solid surface countertops.
Frequently Asked Questions
What is the difference between 16 gauge and 18 gauge stainless steel for a kitchen sink?
Gauge measures steel thickness — the lower the number, the thicker the metal. A 16 gauge bowl has thicker walls than an 18 gauge bowl, which reduces flex and tends to dampen vibration from running water. For a secondary or prep sink that sees regular daily use, 16 gauge holds up well and feels more substantial underhand.
What countertop materials work with this undermount sink?
Undermount sinks in the Select Series are designed for installation in solid countertop materials such as quartz, granite, and solid surface. The installation method follows the countertop material's own guidelines, and the faucet mounts through the countertop deck behind the bowl since the sink has no integral faucet deck.
Does the box of 40 contain 40 individual sinks?
Yes. Each box contains 40 units of the same SU73N sink. This pack quantity is intended for volume purchasing — multi-unit residential builds, dealer stocking orders, and contractor supply runs — rather than single-installation purchases.
Are grids, strainers, or a drain assembly included?
This SKU ships as a bare sink. Basket strainers, bottom grids, and drain assemblies are sold separately. Check the Select Series accessories to match compatible grids and strainers to this bowl.
A Compact Bowl That Earns Its Place
When the station is secondary but the spec still needs to hold up, a 16 gauge bowl with tight-radius corners in a compact undermount footprint covers the ground between economy and overbuilt — at a quantity that makes multi-unit projects straightforward to source.
