A 16-Gauge Stainless Steel Sink Built for Everyday Kitchen Work

The Karran Select SU75N is a single-bowl undermount kitchen sink in 16-gauge stainless steel, sized at 32 inches wide and designed to mount beneath granite, quartz, or solid surface countertops in a 36-inch or wider base cabinet.

Key Features

• 16-gauge stainless steel construction for a thicker, more rigid bowl than standard 18-gauge sinks.
• Single bowl measuring 30 x 16 inches inside with a 9-1/2 inch interior depth for handling large pots and sheet pans.
• Undermount installation into granite, quartz, or solid surface countertops.
• 3-1/2 inch drain opening compatible with standard kitchen basket strainers and disposal flanges.
• Requires a minimum 36-inch base cabinet for proper fit and installation clearance.

One Deep Bowl That Handles the Full Kitchen Load

A single-bowl sink of this depth excels where volume and versatility matter more than separating tasks into two smaller basins. The 9-1/2 inch interior depth gives real clearance for soaking stock pots, rinsing sheet pans flat, or bathing a cutting board without fighting the rim. There is no divider to work around, and the full 30-inch interior length means large items stay fully submerged or under the faucet stream. For a household that cooks regularly or a kitchen that sees high-volume prep, this configuration makes daily cleanup faster and less cramped.

Stainless Steel at a Gauge That Holds Its Shape

The sink is fabricated from 16-gauge stainless steel, a full step thicker than the 18-gauge material common in value-tier undermount sinks. Thicker gauge means the bowl walls flex less under load, deadens sound more readily, and holds its flat bottom geometry over time. The stainless finish reads as a clean, neutral surface that coordinates with professional-style faucets, stainless appliances, and both light and dark countertop materials. It takes routine cleaning without specialized products, and the material makeup resists the oxidation and corrosion that undermines lighter-gauge bowls in a wet kitchen environment.

The Right Fit for a Solid Countertop Remodel or New Build

This sink is an undermount, which means it mounts beneath the countertop surface so the counter edge runs cleanly to the bowl opening with no lip or rim above the work surface. That makes wiping debris directly into the sink straightforward. It is compatible with granite, quartz, and solid surface countertops, the three common hard-surface materials that provide the bonding and edge support an undermount installation requires. Cabinet shops and contractors speccing a new kitchen build or a full countertop replacement will find this sink pairs naturally with stone and engineered stone fabrications. Homeowners completing a countertop upgrade who want a stainless bowl to match stainless appliances will find the proportions and gauge appropriate for a main kitchen sink position. Because it is an undermount, it requires a new countertop or a countertop being fabricated fresh around it rather than a drop-in replacement into an existing cutout.
