It serves as a stunning centerpiece for any high-end kitchen remodel, offering a perfect balance of form and function.
Equipped with specialized soundproofing, this basin utilizes NoiseDefend technology to create a whisper-quiet kitchen environment by eliminating vibration and clatter. The dual-bowl configuration provides the ultimate versatility for multitasking, allowing you to soak large pots in one side while rinsing produce in the other.

Inside the Feature
Understanding the Advantage of TRU16 Gauge Steel
In the world of stainless steel, the gauge number refers to the thickness of the metal, but the scale works in reverse. While many standard sinks use 18 or 20-gauge steel, the Kraus Standart PRO Series utilizes TRU16, which is significantly thicker. Think of it like the difference between a thin aluminum can and a heavy-duty cast iron skillet; the thicker 16-gauge steel is much more rigid and less prone to the 'pinging' sound often associated with thinner basins. This added mass naturally dampens vibrations and resists denting from heavy pots, ensuring the sink maintains its structural integrity and premium feel even after decades of heavy use.
Installation Guide
Use the provided cutout template to ensure a precise fit for your undermount installation, allowing for the desired reveal.
Verify that your base cabinet is at least 33 inches wide to provide adequate structural support for this heavy 16-gauge unit.
Apply a bead of professional-grade silicone sealant to the sink rim before securing it with the included mounting brackets for a watertight seal.
When installing a garbage disposal, ensure you use a compatible 3.5-inch flange kit to maintain the sink's optimal drainage performance.
Care & Maintenance
Rinse After Use: Wash away food particles and soap residue daily to prevent the formation of mineral deposits on the satin finish.
Avoid Steel Wool: Never use steel wool or abrasive scouring pads, as these can leave iron particles that may cause surface rust.
Dry with Microfiber: Wipe the sink dry after its final use each day to maintain the commercial-grade sheen and prevent water spots.
Clean the Grids: Periodically remove and clean the protective bottom grids to ensure no debris is trapped against the sink floor.
Follow the Grain: When using a stainless steel cleaner, always rub in the direction of the brushed finish for a consistent look.

What Customers Are Saying
A homeowner in Nashville, Tennessee, upgraded their kitchen to accommodate a large family and needed a sink that could handle heavy cast iron cookware without denting.
The depth and thickness of this Kraus sink are incredible; I can stack dishes from a dinner party for six and still have room to work. The soundproofing is so good that I barely hear the garbage disposal anymore.

Beyond the Technical Specs
Uncompromising Quality and Brand Trust
Kraus has built a reputation as a leader in kitchen innovation by focusing on materials that exceed industry standards. The Standart PRO Series is a direct reflection of this commitment, utilizing high-grade T304 stainless steel with an 18/10 chromium/nickel content. This isn't just a sink; it is a long-term investment in your home's infrastructure. While other sinks may thin out at the corners during the manufacturing process, Kraus ensures that the 16-gauge thickness remains consistent throughout the entire basin. This structural integrity means you won't have to worry about warping or bending, even when the sink is subjected to extreme thermal shocks from boiling water or ice-cold rinses.
Beyond its physical strength, this sink provides a significant boost to your kitchen's operating efficiency. The undermount design creates a seamless transition from the counter to the bowl, allowing you to sweep crumbs and water directly into the basin for a more hygienic workspace. The reduction in maintenance costs is also noteworthy; the scratch-resistant satin finish and the included protective grids mean you won't spend hours trying to buff out scuffs or worrying about the impact of heavy cookware. For the modern homeowner who values both time and quality, the KHU103-33 offers a professional kitchen experience that is as easy to maintain as it is beautiful to look at.
