A Workstation Sink Built For High-Volume Kitchen Prep
The Karran WS-39 is a 16 gauge stainless steel undermount workstation sink designed around a single oversized bowl and an integrated prep ledge. The ledge supports a suite of included accessories that slide directly over the bowl, turning the sink into an active prep zone without claiming additional counter space. Sold as a -PK1 kit, this model ships with the accessories needed to put the ledge to work from day one.
Key Features
• 16 Gauge Stainless Steel Construction: The thicker 16 gauge bowl delivers a noticeably more rigid, quieter sink compared to standard 18 gauge alternatives.
• Integrated Workstation Ledge: A built-in rim ledge supports sliding prep and drying accessories directly above the bowl, keeping countertops clear during active use.
• Single Extra-Large Bowl: The uninterrupted interior handles oversized cookware, sheet pans, and large cutting tasks without a divider in the way.
• 10-Inch Bowl Depth: The deep basin comfortably accommodates tall stockpots and oversized items with room to spare.
• PK1 Kit Includes Accessories: Ships with a bottom grid, basket strainer, cutting board, colander, drying rack, and Luster Pro oil so the sink is ready for full workstation use out of the box.
• Undermount Installation: Mounts beneath the countertop for a clean, wipe-down edge and an unobstructed counter surface around the sink.
Putting the Ledge to Work
The workstation format changes how prep happens at the sink. Instead of using cutting boards and colanders on a separate section of counter, the integrated ledge positions them directly over the bowl. Trimming vegetables over the colander, rinsing produce onto the cutting board, and air-drying just-washed items on the rack all happen within the sink footprint. For kitchens where counter space is at a premium or where the workflow calls for keeping prep and cleanup in one area, the 39-inch single bowl gives enough ledge run to keep multiple accessories staged at once.
The deep bowl is the other practical advantage. At 10 inches, it handles the tall Dutch ovens, stockpots, and large hotel pans that a shallower bowl would force you to tilt awkwardly. The bottom grid protects the basin floor and keeps cookware elevated above any standing water.
Material and Build Quality
The WS-39 is an Elite series sink, which means 16 gauge Type 304 stainless steel throughout. Sixteen gauge is meaningfully thicker than the 18 gauge used in standard-grade sinks, and the difference shows in reduced flex, lower resonance, and a more substantial feel underhand. The brushed satin finish on the bowl interior is a practical choice as much as an aesthetic one: it minimizes the appearance of water spots and light surface marks in daily use. The included Luster Pro oil is Karran's named maintenance product for keeping the stainless finish looking its best over time.
Who This Sink Suits
The WS-39 fits best in a kitchen where one person or a household does serious daily cooking. The extra-long single bowl rewards cooks who need unbroken interior space for soaking, cleaning, or staging large items. Cabinet and countertop fabricators specifying undermount installations in solid surface, stone, or quartz will find the undermount profile straightforward to work with. Renovation contractors replacing an existing undermount in a wider sink base will appreciate that the 39-inch footprint fills a larger cabinet run than a standard 30-inch or 33-inch undermount.
For households or light-commercial kitchens that want a prep-forward layout without a separate prep sink, the workstation format consolidates that function into the primary sink location.
Frequently Asked Questions
What accessories are included in the PK1 kit?
This sink ships with a bottom grid, basket strainer, cutting board, colander, drying rack, and Luster Pro oil. No separate accessory purchase is needed to use the workstation ledge system as intended.
Is a drain included with this sink?
The basket strainer is included as part of the PK1 kit. A separate drain tailpiece and plumbing connections are not included and will be required to complete the installation.
What countertop materials work with this undermount installation?
Undermount installation suits solid surface, stone, quartz, and similar countertop materials where the installer can finish the cutout edge. The mounting method and countertop compatibility should be confirmed with your fabricator before cutting.
Can the workstation accessories be purchased separately later?
Yes. Karran offers compatible workstation accessories for this series individually. Any replacement or add-on accessory should be confirmed for fit with the WS-39 specifically, as accessory dimensions are model-family-specific.
Does this sink require a special cabinet size?
At 39 inches overall, this sink requires a sink base cabinet large enough to accommodate that width. Confirm the minimum cabinet size against your cabinet run before ordering, as this is a larger-than-standard footprint.
One Sink, One Organized Workspace
The WS-39 kit combines a deep, 16 gauge single bowl with a full set of workstation accessories, so the sink functions as a complete prep and cleanup station from the moment it is installed.
