A Thick-Gauge Double Bowl Sink For High-Volume Kitchen Work
The Karran Select Series SU76 is a 16 gauge stainless steel undermount sink in a 50/50 equal double bowl configuration, sized at 30 by 18 by 9-1/2 inches. Built for kitchens where both sides of the sink see constant use, it delivers the structural rigidity of heavier-gauge steel with a contemporary tight-radius corner profile that suits modern cabinetry.
Key Features
• 16 Gauge Construction: Thicker steel wall than standard 18 gauge sinks provides a denser, more rigid bowl that resists flexing under load.
• Equal 50/50 Bowl Layout: Two identically sized basins give each side equal working capacity for wash-and-rinse workflows or simultaneous prep tasks.
• Tight-Radius Corners: Squared interior corners give the bowl a clean, architectural look that aligns with contemporary kitchen designs.
• Undermount Installation: Mounts beneath the countertop so the counter surface wipes clean straight to the bowl edge with no rim in the way.
• 9-1/2 Inch Deep Bowls: Extra depth keeps splashing contained and accommodates tall stockpots and sheet pans without crowding.
Built for Two-Station Kitchen Workflows
An equal double bowl layout works well whenever two tasks need to run at the same time. One side holds a soaking pot while the other stays clear for rinsing produce or plating. For households that hand-wash dishes, the symmetrical split makes wash-and-rinse setups natural and repeatable. In a cabinet shop break room or a professional kitchen renovation where the primary sink sees heavy rotation, having two full-depth basins side by side means neither side becomes the bottleneck.
The 30 by 18 inch overall footprint fits a standard 33 inch or larger sink base cabinet, making it straightforward to specify for new builds or sink replacements where the rough opening is already established. Because this is an undermount design, the faucet and any soap dispenser mount through the countertop behind the sink rather than through a deck on the sink itself.
16 Gauge Steel and Tight-Radius Design
The Select Series earns its name from its gauge. At 16 gauge, the steel is measurably thicker than the 18 gauge material used in standard-line stainless sinks, which translates to a bowl that sounds quieter when water hits it and holds its shape through years of daily use. The brushed satin finish common to this series reduces the visibility of water spots and minor surface marks between cleanings.
Tight-radius corners at the bowl interior create a profile that reads more squared than the rounded interiors on traditional stainless sinks. That geometry suits kitchens with contemporary flat-front cabinetry and clean-line countertop materials. Cleaning along the corners requires no extra effort compared with a wider radius because the interior surface transitions are gentle enough for a standard sponge.
Right for Renovations, Ideal for High-Use Kitchens
Cabinet shops installing kitchens in residential projects frequently specify this sink category for clients who want a stainless look without sacrificing bowl depth or structural quality. The 16 gauge build means the sink will hold up in a high-activity kitchen where a lighter gauge would eventually show wear. Homeowners doing a full kitchen renovation get a sink that pairs with stone, quartz, or solid surface countertops and requires no visible rim after installation. Designers specifying for a client who wants a contemporary twin-basin layout without the visual weight of a heavier material will find the brushed stainless surface coordinates easily with a range of hardware finishes.
Frequently Asked Questions
Does this sink require any special cabinet support for the undermount installation?
Undermount sinks of this size depend on the countertop and its substrate for support rather than the cabinet itself. The countertop material and its fabricator determine the fastening method — clips, brackets, or adhesive — appropriate for the surface. Confirm the attachment approach with the countertop installer before the sink is ordered.
Is a drain or grid included with the SU76?
The SU76 is sold as a bare sink. Basket strainers, bottom grids, and other accessories are sold separately. Karran offers model-matched grids and strainers for the Select Series — confirm the model numbers against this sink before ordering.
Where does the faucet mount on an undermount sink with no deck?
On this sink, the faucet mounts through holes drilled in the countertop behind the bowl. The number and spacing of those holes is determined by the faucet selected and confirmed with the countertop fabricator before the cutout is made.
What is the difference between 16 gauge and 18 gauge for a working kitchen?
Gauge describes steel thickness — a lower number means thicker material. At 16 gauge, this sink's steel is noticeably denser than an 18 gauge bowl, which reduces flex when pressure is applied to the bowl bottom and generally produces a quieter sound when water and dishes contact the surface.
A Sink That Earns Its Place Every Day
The Select Series SU76 brings 16 gauge stainless construction, a full-depth equal double bowl layout, and a clean undermount profile together in a 30 inch footprint that fits standard kitchen builds — a combination that performs reliably through the heaviest daily use.
