The KRAUS Kore 32-Inch Undermount Workstation Sink: A Detailed Look at the KWU110-32
When planning a kitchen renovation or upgrade, the sink is often one of the most overlooked yet frequently used elements in the space. It’s where meals begin—with washing and chopping produce—and where they end, with pots, pans, and dishes needing thorough cleaning. In recent years, the workstation sink concept has gained considerable attention among homeowners and design professionals alike, offering a way to maximize both functionality and counter space in one integrated unit.
The KRAUS Kore 32-Inch Undermount Workstation 16 Gauge Single Bowl Stainless Steel Kitchen Sink with Accessories, model KWU110-32, represents one approach to this growing category. Rather than serving as a simple basin for washing, this sink is engineered with an integrated ledge system that supports sliding accessories, effectively transforming the sink area into a multifunctional prep and cleanup zone. This article provides a comprehensive, objective overview of what this sink offers, its potential applications, and important factors to consider before making a purchasing decision.
Understanding the Workstation Sink Concept
Traditional kitchen sinks serve one primary purpose: holding water for washing dishes, produce, and cookware. The workstation sink expands on this concept by incorporating a built-in ledge—sometimes referred to as a rail or lip system—that runs along the perimeter of the sink basin. This ledge allows specially designed accessories to slide or rest across the sink, creating a temporary work surface directly over the basin.
The practical advantage is straightforward. Instead of taking up valuable counter space with a cutting board or drying rack, these tasks can be performed directly over the sink. Food scraps can be swept directly into the basin, and water from rinsed produce or washed dishes drains naturally into the sink below. For kitchens with limited counter space—or for those who simply prefer a cleaner, more organized workspace—this design offers a compelling alternative to traditional sink configurations.
The KWU110-32 is part of KRAUS’s Kore line of workstation sinks, which are available in various sizes, mounting styles, and finishes. This particular model is a 32-inch undermount unit finished in stainless steel, designed to install beneath the countertop for a seamless, modern look.
Key Features of the KWU110-32
16-Gauge Stainless Steel Construction
One of the most significant considerations when evaluating any stainless steel sink is the gauge of the material. The gauge number indicates the thickness of the steel—counterintuitively, a lower number corresponds to thicker material. The KWU110-32 is constructed from 16-gauge stainless steel, which is thicker and more substantial than the 18-gauge steel found in many standard sinks.
KRAUS refers to this material as TRU16, describing it as their thickest 16-gauge steel. The practical implications of thicker gauge steel include enhanced resistance to dents from dropped cookware, greater structural integrity under heavy loads, and improved durability over years of daily use. The added material thickness also contributes to better sound dampening characteristics, a feature that is further enhanced by other design elements discussed below.
It is worth noting that while 16-gauge steel is thicker and generally more durable than 18-gauge, it is also heavier. The assembled weight of this sink is approximately 25 to 26 pounds, which is a consideration for both installation and the structural support required from the underlying cabinetry.
Integrated Workstation Ledge
The defining feature of this sink is its integrated workstation ledge. This built-in lip runs along the sides of the basin and is designed to accommodate sliding accessories. The ledge allows accessories such as the included cutting board and roll-up drying rack to sit securely across the sink, creating a stable work surface that spans the basin.
This design effectively adds usable workspace to the kitchen without requiring additional counter area. The accessories can be positioned anywhere along the ledge, sliding from side to side as needed, and can be removed entirely when not in use, leaving a conventional sink basin.
Large Single Bowl Design
The KWU110-32 features a single-bowl configuration with an outer sink dimension of 32 inches in length, 19 inches in width, and 10½ inches in depth. The interior bowl dimensions are 30 inches long by 16 inches wide by 10 inches deep.
A single-bowl design offers certain advantages over double-bowl configurations. Without a divider in the middle, the entire basin is available for washing oversized items such as large stockpots, roasting pans, baking sheets, and tall vases. The uninterrupted workspace also makes it easier to soak large items or wash bulky cookware that might not fit comfortably in a divided sink.
The 10-inch depth of the bowl is another notable characteristic. A deeper basin helps contain water and reduce splashing during washing tasks, which can be particularly beneficial when cleaning large pots or when children are involved in kitchen activities. However, deeper sinks may require some adjustment for users who are shorter or who have mobility limitations, as reaching the bottom of the basin can require more bending.
NoiseDefend Sound Dampening
Kitchen sink noise is often an underappreciated consideration until a household experiences a particularly loud garbage disposal or the clatter of dishes being washed. The KWU110-32 incorporates NoiseDefend soundproofing technology, which consists of large sound-dampening pads applied to the sides of the sink.
These pads are designed to absorb vibration and reduce the transmission of noise from running water, dish clatter, and garbage disposal operation. The sink also features a full anti-condensation undercoating, which serves the dual purpose of reducing noise and preventing moisture buildup on the underside of the sink that could damage cabinet interiors.
Undermount Installation
The KWU110-32 is designed for undermount installation, meaning the sink is installed beneath the countertop rather than resting on top of it. This installation method creates a seamless transition between the countertop surface and the sink basin, with no exposed lip or mounting deck.
From a practical standpoint, undermount installation simplifies cleanup. Crumbs, water, and food debris can be wiped directly from the countertop into the sink without catching on a raised edge. The absence of a lip also means there is no crevice where debris can accumulate, making the sink easier to keep clean.
However, undermount installation is generally more complex than drop-in or top-mount installation and typically requires professional assistance. The sink must be securely attached to the underside of the countertop, and the weight of the sink—particularly when filled with water and dishes—must be adequately supported.
Rear-Offset Drain
The drain on the KWU110-32 is positioned toward the rear of the basin, a design choice that offers several practical benefits. A rear-offset drain creates more usable space in the sink bowl by eliminating the need for a centrally located drain assembly that could interfere with large items placed in the basin.
Additionally, the rear drain position allows for more storage space underneath the sink in the base cabinet. With the drain and plumbing positioned toward the back of the cabinet, there is more room for items stored at the front of the under-sink area.
The sink features a sloped bottom with channel grooves designed to promote efficient drainage and prevent water from pooling in the basin. The slope directs water toward the rear-offset drain, while the channel grooves provide pathways for water to flow even when dishes are resting in the sink.
Included Accessories
One of the distinguishing features of the KWU110-32 is the comprehensive set of accessories included with the sink. The kit includes:
- Heavy-duty bamboo cutting board: Designed to fit across the workstation ledge, this cutting board provides a stable surface for food preparation directly over the sink. The board features built-in drainage grooves.
- Roll-up dish drying rack: A flexible silicone or similar material rack that rests across the sink for drying dishes. It is described as dishwasher-safe, heat-safe, and designed to roll up for compact storage when not in use.
- Protective bottom grid: A stainless steel rack that sits on the bottom of the sink bowl, elevating dishes and cookware off the sink surface. This helps protect the sink from scratches and promotes better drainage.
- Drain assembly with strainer: The drain hardware includes a strainer to catch food debris and prevent clogs.
- Removable decorative drain cover: A cover that conceals the drain opening for a cleaner aesthetic.
- Mounting hardware and cutout template: All necessary hardware for installation is included, along with a template for cutting the countertop opening.
The inclusion of these accessories adds value by providing functional items that might otherwise need to be purchased separately. However, the accessories are specifically designed to work with the integrated ledge system, so they may not be interchangeable with accessories from other brands.
Finish and Maintenance
The sink features a smooth satin finish that is described as wear-resistant and easy to clean. The finish is not prone to corrosion or rust, and the smooth surface resists the accumulation of food debris and mineral deposits.
The bottom of the bowl features gently rounded corners rather than sharp angles. This design choice serves two purposes: it reduces the buildup of food particles and debris in hard-to-reach corners, and it makes the sink easier to wipe clean. However, it is worth noting that some workstation sink designs feature tighter, more angular corners for a different aesthetic; the trade-off is often between ease of cleaning and visual preference.
How the KWU110-32 Can Be Used
The workstation sink concept opens up a range of usage possibilities beyond conventional sink functions.
Food Preparation Station
With the bamboo cutting board positioned across the workstation ledge, the sink becomes a dedicated food preparation area. Chopping vegetables, mincing herbs, and slicing fruits can be done directly over the basin. Any scraps or peelings can be swept directly into the sink, and rinsed produce can be transferred immediately to the cutting board. This workflow minimizes the need to move between the sink and a separate countertop preparation area, reducing both mess and the number of surfaces that require cleaning.
Dish Drying
The roll-up drying rack can be placed across the sink to create a dedicated drying area. Washed dishes, glasses, and utensils can be placed on the rack, with water draining directly into the sink below. This eliminates the need for a separate dish drying rack on the countertop, freeing up counter space and reducing the visual clutter of a permanent drying rack.
When the drying rack is not needed, it can be rolled up and stored away, leaving the sink fully available for other tasks.
Soaking and Cleaning Oversized Items
The large single bowl provides ample space for soaking and cleaning oversized items that would not fit comfortably in a standard double-bowl sink. Large stockpots, roasting pans, baking sheets, and even certain small appliances can be accommodated in the 30-inch by 16-inch basin.
Multi-Tasking
The workstation design allows for multiple tasks to be performed simultaneously. For example, one person might be chopping vegetables on the cutting board while another uses the sink basin for rinsing produce or washing dishes—though the single-bowl design means that the basin cannot be used for washing while the cutting board is in place. The accessories are designed to be easily removable, allowing the sink to transition between different functions as needed.
Who the KWU110-32 May Be Suitable For
Homeowners with Limited Counter Space
For kitchens where counter space is at a premium, the workstation sink offers a way to add functional workspace without expanding the kitchen footprint. By bringing food preparation and dish drying tasks over the sink, the countertops remain clear for other uses.
Those Who Cook Frequently
Home cooks who prepare meals regularly may appreciate the streamlined workflow that a workstation sink enables. The ability to chop, rinse, and clean in one integrated area can reduce the number of steps involved in meal preparation and cleanup.
Households with Large Cookware
For those who frequently use large pots, roasting pans, or baking sheets, the large single-bowl design offers practical advantages over divided sinks. The uninterrupted basin accommodates oversized items that might not fit in a standard sink.
Those Undertaking Kitchen Renovations
The KWU110-32 is designed as part of a coordinated product line, and it can be paired with other KRAUS products such as faucets, garbage disposals, and water filtration systems. For homeowners undertaking a complete kitchen renovation, this compatibility may simplify the selection process.
Those Who Value a Modern Aesthetic
The undermount installation, clean lines, and satin stainless steel finish contribute to a contemporary kitchen aesthetic. The absence of a visible mounting deck and the seamless transition between countertop and sink create a clean, streamlined appearance.
Important Things to Consider
Cabinet Size Requirements
The KWU110-32 requires a minimum cabinet size of 36 inches. This is an important consideration for any installation, as the sink will not fit in smaller cabinets. Before purchasing, it is essential to measure the available cabinet space accurately and confirm that it meets or exceeds this requirement.
Installation Complexity
Undermount installation is not a typical DIY project for most homeowners. Proper installation requires securely attaching the sink to the underside of the countertop, ensuring adequate support, and connecting the plumbing. Professional installation is generally recommended, and the associated labor costs should be factored into the overall budget.
Drainage Considerations
Some users have reported drainage issues with the KWU110-32, noting that water can pool in the corners of the basin despite the sloped design. Improper installation may exacerbate this issue. Additionally, some observations suggest that adding a garbage disposal can increase water and food particle accumulation in certain areas of the sink.
It is worth noting that drainage performance can be influenced by multiple factors, including the quality of the installation, the specific plumbing configuration, and the level of slope in the drain lines. Ensuring proper installation and considering the use of a high-quality garbage disposal may help mitigate drainage concerns.
Scratch Susceptibility
While stainless steel is known for its durability, it is not scratch-proof. Some users have reported that the sink surface can scratch relatively easily. The protective bottom grid is designed to help prevent scratches from dishes and cookware resting on the sink surface, and using the grid consistently may help preserve the finish.
It is also worth considering that the satin finish may help mask minor scratches over time, as the texture can make fine scratches less visible than they would be on a highly polished surface.
Weight Considerations
At approximately 25 to 26 pounds, this sink is heavier than many standard sinks. The weight must be supported by the countertop and cabinetry, and the undermount installation must be sufficiently robust to hold the sink securely, particularly when filled with water and dishes.
Compatibility with Existing Fixtures
The sink does not include pre-drilled faucet holes, as the faucet is typically mounted separately on the countertop or wall. This offers flexibility in faucet selection but also means that the countertop must be prepared for faucet installation independently of the sink.
Warranty
The KWU110-32 is covered by a limited lifetime warranty for residential use and a 1-year limited commercial warranty. Understanding the terms and conditions of the warranty—including what is covered, what is excluded, and how to make a claim—is advisable before purchasing.
Comparison of General Categories
When considering a workstation sink like the KWU110-32, it can be helpful to understand how it compares to other types of kitchen sinks in terms of general categories.
Workstation Sinks vs. Traditional Sinks
Traditional sinks consist of a simple basin (or basins) with no integrated ledge or accessory system. They are generally less expensive than workstation sinks and may be simpler to install. However, they do not offer the same multifunctional capabilities, and food preparation or dish drying tasks must be performed on separate countertop surfaces.
Workstation sinks like the KWU110-32 incorporate the ledge system and included accessories, effectively adding workspace to the kitchen. The trade-off is a higher purchase price and, in some cases, more complex installation.
16-Gauge vs. 18-Gauge Stainless Steel
The gauge of stainless steel is a key differentiator among sinks. Sixteen-gauge steel is thicker and generally more durable than 18-gauge steel. It offers better resistance to dents, greater structural integrity, and improved sound dampening characteristics. However, it is also heavier and typically more expensive.
Eighteen-gauge steel is thinner and lighter, which can make it easier to install and more affordable. However, it may be more susceptible to denting and may transmit more noise during use.
Undermount vs. Drop-In Installation
Undermount sinks like the KWU110-32 are installed beneath the countertop, creating a seamless transition and making it easier to wipe debris directly into the sink. They offer a clean, modern aesthetic but require professional installation and must be compatible with the countertop material.
Drop-in or top-mount sinks are installed from above, with a lip that rests on the countertop surface. They are generally easier to install and can be used with a wider range of countertop materials. However, the lip can trap debris and make cleaning slightly more challenging.
Single Bowl vs. Double Bowl
Single-bowl sinks like the KWU110-32 offer an uninterrupted workspace that can accommodate oversized items. They provide maximum flexibility for washing large cookware but do not allow for simultaneous multi-tasking in separate basins.
Double-bowl sinks offer separate basins that can be used for different purposes simultaneously—for example, washing in one basin and rinsing in the other. However, the divided space may not accommodate oversized items as comfortably.
