An Undermount Sink Built for High-Volume Kitchen Work
The Karran Select Series SU74 is a 16 gauge stainless steel undermount sink designed for kitchens where uninterrupted bowl space and durable construction are non-negotiable. Its extra-large single bowl gives a single continuous workspace suited to serious cooking, entertaining, and busy household routines.
Key Features
• 16 gauge stainless steel construction delivers a noticeably thicker, more rigid bowl than standard 18 gauge alternatives.
• Extra-large single bowl provides an unobstructed interior that handles full sheet pans, large stockpots, and oversized cookware without a divider in the way.
• Tight-radius corners give the bowl a clean, squared interior profile suited to contemporary kitchen designs.
• Undermount installation keeps the counter edge fully exposed and wipeable, with no rim to collect debris.
• 30 x 18 x 9-1/2 inch bowl offers generous depth for containing splashes during heavy prep and cleanup tasks.
Where This Sink Earns Its Place
A sink without a divider trades flexibility for capacity. This one is the right call when a single large basin matters more than a two-station workflow — cleaning sheet pans flat, soaking a large stock pot, or setting up a dedicated prep station on an island run. The 9-1/2 inch depth keeps water contained even when the bowl is heavily loaded, making it practical for anyone who cooks frequently or entertains in volume. Cabinet shops specifying sinks for kitchen projects and contractors installing for clients who prioritize functionality over a split-bowl setup will find the Select Series a straightforward, spec-appropriate choice.
Construction and Material
The Select Series targets the space between entry-level 18 gauge sinks and premium commercial builds. At 16 gauge, the bowl resists flexing and the acoustic deadening that comes from thicker steel reduces noise noticeably compared to thinner alternatives. Tight-radius corners are a defining Select Series detail — they bring the interior profile closer to a square, which reads as a sharper, more modern look while making the bottom easier to clean. The brushed satin stainless finish coordinates with most faucet and hardware finishes without calling attention to itself.
The Right Kitchen for This Sink
This sink suits undermount applications in stone, quartz, and solid surface countertops where a finished edge is part of the design. It fits kitchens where the primary user regularly works with large cookware or batch cooks and would find a center divider an obstacle rather than an asset. Designers specifying for a modern or transitional kitchen will find the tight-radius corners consistent with the clean-line aesthetic many clients are requesting. Contractors who need a dependable, mid-to-upper-tier stainless option for production builds will appreciate that the 16 gauge rating is explicit — not something to guess at from the price point.
Frequently Asked Questions
What countertop materials work with undermount installation for this sink?
Undermount installation is standard for stone, granite, quartz, and solid surface countertops, where the countertop edge is finished and left exposed above the bowl. It is not the typical choice for laminate, where a top mount or seamless series is a better fit.
Does this sink include a bottom grid or basket strainer?
Included components for this SKU should be confirmed at the time of order. Compatible grids and strainers sized for the Select Series are available as companion items if not specified as included.
Why choose 16 gauge over 18 gauge stainless for a kitchen sink?
Gauge refers to the steel thickness — 16 gauge is thicker than 18 gauge. A thicker bowl flexes less under load, tends to be quieter when water runs against it, and holds its shape better over years of use. For a high-use kitchen, the upgrade is worth the difference.
Where does the faucet mount with an undermount sink that has no deck?
When a sink has no integrated faucet deck — as is typical with undermount stainless designs — the faucet mounts through holes drilled in the countertop behind the bowl. Your countertop fabricator handles those drillings during the install.
One Basin, Full Capacity
