16-Gauge Thickness, Single-Bowl Freedom
The Karran Select Series SU74N is a 16-gauge stainless steel undermount kitchen sink built around one uncommonly large, uninterrupted bowl. Designed for kitchens where maximum basin workspace matters more than divided sections, it brings heavy-gauge construction to an extra-large footprint that suits working kitchens of every kind.
Key Features
• 16-gauge stainless steel construction delivers a noticeably thicker, more rigid bowl than standard 18-gauge models.
• Extra-large single bowl at 30 by 18 inches provides an uninterrupted basin with no divider limiting usable space.
• 9-1/2 inch bowl depth accommodates tall stockpots, sheet pans, and full-size colanders without overhang.
• Tight-radius corners give the interior a squared, architectural profile and make the basin easier to wipe clean edge to edge.
• Undermount installation keeps the counter surface free of a visible rim for a clean, wipe-through look.
• Sold in a box of 40, making it a practical stocking option for cabinet shops, builders, and distributors supplying multiple kitchens.
Where This Sink Fits the Job
A single-bowl sink at this size earns its place in kitchens built around serious cooking or food prep. There is no center divider to navigate around when sliding a full sheet pan or a large Dutch oven into the basin. The 9-1/2 inch depth keeps tall pots fully in the bowl rather than tipping against a shallow rim, and it leaves enough clearance for a garbage disposal mounted underneath without sacrificing working depth. That combination of open width and generous depth also makes this basin practical as an island prep sink where a second cook needs room to work independently of the main station. For multi-family residential builds and kitchen renovations going through several units at once, the 40-unit box quantity lines up well with project-scale ordering.
Construction and Finish
The Select Series positions 16-gauge steel and tight-radius corners as its two defining construction points, and the SU74N delivers both in a single-bowl format. The thicker 16-gauge wall resists flex and deadens sound better than thinner alternatives, and it holds its shape over years of daily impact from pots, utensils, and cast-iron cookware. The tight-radius corners carry that precision through the interior: the near-square profile reads as contemporary on the finished countertop and eliminates the deep curved pocket where residue collects in a standard rounded bowl. The satin brushed stainless finish handles water spots and fine scratches in stride, maintaining a consistent look through normal kitchen use.
Who Orders This Sink
Cabinet shops and kitchen designers specifying for open-concept kitchens or large-format islands will find the proportions here match the cabinet runs they are already building to. The 30 by 18 inch footprint requires a minimum cabinet base of appropriate width, so confirm the sink base before ordering. Contractors supplying tract builds and multi-unit renovations benefit from the 40-unit pack: consistent spec across every kitchen, one line item, one delivery. Homeowners upgrading a single kitchen who want a clean, modern basin without the visual and physical interruption of a center divider will get exactly that from this bowl. The undermount path keeps the install straightforward on quartz, granite, and solid surface countertops where a finished stone edge is part of the design intent.
Frequently Asked Questions
Does this sink require the faucet to mount through the countertop?
Yes. As an undermount model, the SU74N has no faucet deck, so the faucet, soap dispenser, and any other accessories mount through holes drilled in the countertop behind the bowl.
Is a bottom grid or basket strainer included?
This SKU is a bare sink. Grids, basket strainers, and drain assemblies are sold separately. Karran offers model-matched accessories; confirm the grid and strainer part numbers against the SU74N before ordering.
What countertop materials work with this undermount sink?
The SU74N is suited to quartz, granite, and solid surface countertops where an undermount installation is standard practice. It is not an Edge Series seamless model and does not install flush with laminate by that method.
Why does gauge matter on a stainless sink?
Lower gauge numbers mean thicker steel. At 16 gauge, the Select Series bowl has more mass than an 18-gauge alternative, which translates to less flex under load, better resistance to denting, and reduced noise from running water and dropped utensils.
Can this sink accommodate a garbage disposal?
The single-bowl layout is compatible with a disposal mounted at the drain, but disposal compatibility depends on the specific unit and the available under-cabinet clearance at the install location. Verify clearances with your disposal model before installation.
One Basin, Built to Handle the Full Load
The Karran Select SU74N brings 16-gauge construction and an unobstructed 30-inch basin to kitchens that need the space to work. Whether the job is a single high-use kitchen or a full multi-unit build, this sink delivers the thickness, the depth, and the clean-corner profile that hold up over time.
