A Workstation Sink Built for the Widest Kitchens and the Heaviest Prep
The Karran WS-100-PK1 is an extra-large, single-bowl, 16 gauge stainless steel undermount workstation sink measuring 45 by 19 by 10 inches. At this scale, it serves as a fully equipped prep and finishing station for high-volume kitchen environments, professional cooking spaces, and expansive residential kitchens where counter space and capacity need to work in tandem.
Key Features
• 45-inch extra-large single bowl delivers an uninterrupted workspace that accommodates full sheet pans, large stock pots, and oversized cutting boards without a divider breaking up the basin.
• 16 gauge stainless steel construction provides a noticeably denser, more rigid basin wall than 18 gauge alternatives, reducing flex and noise during heavy use.
• Integrated workstation ledge runs the length of the rim and supports sliding accessories directly over the bowl, keeping the surrounding counter clear during active prep.
• Undermount installation positions the bowl beneath the countertop for a clean, wipe-down counter edge with no rim catching debris.
• -PK1 pack includes a model-specific accessory set so the sink arrives ready to use as a prep station out of the box.
• 10-inch bowl depth accommodates tall cookware and creates generous vertical clearance for rinsing and soaking.
Where a Sink This Large Earns Its Place
A 45-inch single bowl is a deliberate choice, not a default. It suits kitchens built around serious cooking: catering prep spaces, professionally equipped home kitchens, and restaurant-adjacent residential builds where the sink handles multiple simultaneous tasks. The uninterrupted basin means a full hotel pan fits flat, a whole fish lays out without folding, and a pot of pasta drains without the divider getting in the way. The integrated ledge extends that capacity by staging the cutting board and colander over the bowl itself, pulling prep off the surrounding counter entirely. For an island or peninsula installation with cabinet runs long enough to support a 45-inch sink base, this configuration turns the sink zone into the kitchen's central work hub.
Gauge, Material, and Build
The 16 gauge stainless steel bowl is meaningfully thicker than the 18 gauge material common in standard sink lines. That extra thickness contributes to a quieter, more stable basin that does not resonate under a running faucet or flex when a heavy pot is set down. The satin brushed finish conceals light surface marks that come with daily kitchen use. Undermount installation hides the rim entirely beneath the countertop, which keeps cleanup fast and the counter line unbroken. This installation path suits solid surface, stone, and quartz countertops and is recommended for professional installation given the sink's size and weight.
Who This Sink Is For
Cabinet shops, design-build firms, and kitchen dealers specifying for high-end residential projects will find the WS-100 at the top of Karran's Elite Workstation line for good reason: it is the largest single-bowl configuration in the series. Homeowners planning a once-and-done kitchen renovation who cook seriously, entertain regularly, or want a sink that grows with the way they use their kitchen will get full value from the scale. This is not a starter sink; it is a commitment to a kitchen organized around the sink as its primary work surface.
What accessories are included in the WS-100-PK1?
The -PK1 pack resolves to the model-specific accessory set Karran states for the WS-100. Confirm the exact component list — grid, basket strainer, cutting board, colander, drying rack, and any additional items — against the Karran WS-100 spec sheet before ordering, as the extended sets on the 90- and 100-series models may include additional items not in smaller WS packs.
What minimum cabinet size does the WS-100 require?
A 45-inch sink requires a sink base cabinet wide enough to support it. Verify the minimum cabinet width against the Karran WS-100 spec sheet before ordering, and confirm the base cabinet run and countertop overhang accommodate the full 45-inch footprint.
Does this sink include a faucet?
No. The -PK1 pack includes the accessory set but not a faucet. Karran's -PK2 workstation packs add a coordinating faucet; if a matched faucet is needed, confirm whether a PK2 configuration is available for this model.
Is a drain or strainer included?
The -PK1 pack includes a basket strainer. A separate drain assembly is not included; source the drain component appropriate for the installation separately.
Can the workstation accessories be replaced or expanded later?
Karran workstation accessories are model-family specific. Replacement and add-on accessories made for the Elite WS series fit the WS-100 ledge. Do not assume accessories from other Karran workstation families span this ledge without checking Karran's fit tables for the WS series.
The Right Sink for a Kitchen Designed Around Real Work
When the kitchen is the room everything else is planned around, the sink at its center should match that ambition. The WS-100-PK1 brings the depth, the gauge, the workspace, and the accessories to support a kitchen that is actually used.
