16 Gauge Stainless Undermount Sink For an Uninterrupted Primary Wash Station
The Karran Select Series SU74-PK1 is a 16 gauge stainless steel undermount kitchen sink built around one large, deep basin sized for serious daily use. It ships as a complete kit, so the basket strainer, bottom grid, and Luster Pro care oil arrive in the same box as the sink.
Key Features
• 16 gauge Type 304 stainless steel delivers a noticeably thicker bowl than standard 18 gauge sinks, resisting dents and flexing under heavy loads.
• Extra-large single bowl accommodates full sheet pans, large stockpots, and oversized cookware without a center divider in the way.
• 9-1/2 inch bowl depth keeps splashing contained and gives room to submerge tall items fully.
• Tight-radius corners give the interior a clean, squared-off profile and make routine cleaning straightforward.
• Undermount installation leaves the countertop edge uninterrupted, supporting a clean wipe-down surface.
• Kit includes basket strainer, bottom grid, and Luster Pro oil, so the sink is ready to install and protect from day one.
Built for the Work That Happens at the Main Sink
A single bowl this size earns its place at the primary wash station. Sheet pans lay flat on the bottom grid without tipping against a divider. A full stockpot drops in and submerges without crowding. Holiday meal prep, catering prep in a private kitchen, or the kind of back-to-back dishwashing a busy household generates — the uninterrupted basin handles all of it without the frustration of splitting a load between two sides. The 9-1/2 inch depth keeps water where it belongs even when the sink is full and things are moving fast.
Select Series Construction and Material
The Select Series stands apart from standard stainless sinks in two ways. First, the gauge: 16 gauge steel is meaningfully thicker than the 18 gauge material used in economy lines, which translates to less drum resonance and a bowl that holds its shape under cast iron and full water weight. Second, the corners: tight-radius interior corners give the basin a modern, architectural look that suits contemporary cabinetry without compromising usable floor space in the bowl. The satin brushed finish hides minor surface marks that accumulate around a working sink. The included Luster Pro oil supports the finish from the first use and keeps the steel looking consistent over time.
The Right Fit for This Sink
This sink is the practical choice for kitchen renovations where the countertop is stone, quartz, or solid surface and the layout calls for one large dedicated wash zone rather than a split-bowl configuration. Cabinet shops specifying a sink for a client's new kitchen build will find the 30 by 18 inch footprint accommodates a 33 inch or larger sink base cabinet comfortably. Homeowners doing a full kitchen gut who want a sink that can handle a household of four without daily compromises will get exactly that here. The kit format simplifies the supply list — strainer and grid do not need to be sourced separately.
What is included in the -PK1 kit?
The kit ships with the SU74 sink, a stainless steel basket strainer, a bottom grid sized for the bowl, and Luster Pro sink care oil.
Does this sink work with a garbage disposal?
Single-bowl sinks are commonly paired with a garbage disposal. You will need a disposal flange compatible with a standard 3-1/2 inch drain opening, sold separately.
Is the faucet included?
No. This is a sink kit only. The faucet mounts through the countertop behind the sink, since the undermount design has no integral faucet deck.
What countertop materials work with this undermount sink?
The Select Series SU74 is a conventional undermount design suited for stone, quartz, and solid surface countertops. It is not a seamless-series sink and does not use the seamless laminate installation method.
Why choose 16 gauge over 18 gauge for a kitchen sink?
Thicker steel — 16 gauge versus 18 gauge — reduces flexing, dampens sound better, and holds up longer under the weight and impact of heavy cookware. It is a meaningful difference in a sink that sees daily use.
One Basin, Ready to Install
The SU74-PK1 brings together the capacity, gauge, and included accessories to set up a high-performing main sink without a separate shopping list — so the install stays on schedule and the kitchen gets back to work.
