A Workstation Sink Built for Serious Depth
The Karran WS-33-PK1 is a 16 gauge stainless steel undermount workstation kitchen sink designed around a 14-inch deep single bowl. That extra depth is the defining feature here: large pots, sheet pans, and bulky cookware drop in without splashing, and the integrated ledge keeps the workstation accessories directly over the bowl where they belong.
Key Features
• 14-inch bowl depth accommodates oversized cookware and deep soaking jobs that shallower workstation sinks cannot handle.
• 16 gauge Type 304 stainless steel construction gives the bowl a noticeably thicker, more rigid feel compared to standard 18 gauge sinks.
• Integrated accessory ledge runs along the bowl rim so the included prep and drying accessories slide and position over the bowl without taking up counter space.
• Undermount installation places the rim beneath the countertop for a clean, wipe-down counter edge with no exposed lip to trap food and water.
• -PK1 kit includes the basket strainer, bottom grid, and Luster Pro care oil so the sink is ready to put to work.
• Single bowl layout, 23 x 18-3/4 inches overall, delivers an uninterrupted basin well suited to high-volume prep and cleanup.
Where the Extra Depth Makes the Difference
Most kitchen workstation sinks run 9 to 10 inches deep. At 14 inches, this bowl changes what you can do without thinking about it. A stockpot fills and drains without clearing the rim. A sheet pan slides in flat. Large mixing bowls rinse without angling over the edge. The integrated ledge means the cutting board, colander, and drying rack still position above that deep bowl, so the workstation workflow stays intact even when the basin is fully loaded. For a renovation, a high-use kitchen, or a shop with a sink that sees serious daily work, the depth removes a friction point that a standard-depth bowl never quite eliminates.
16 Gauge Construction and the PK1 Kit
The Elite series uses 16 gauge stainless steel throughout. The difference in wall thickness compared to 18 gauge is tactile: the bowl doesn't flex under pressure, and the surface holds its look longer under daily contact with heavy cookware. The brushed satin finish reduces the appearance of water spots and minor surface marks. The -PK1 pack resolves to a basket strainer, a bottom grid sized for this bowl, and Luster Pro care oil. The grid lifts items off the bowl floor and protects the finish; the Luster Pro keeps the stainless looking clean between scrubbings. Everything that ships in the box is usable from day one.
Who This Sink Is For
Cabinet shops and woodworkers building or outfitting a professional kitchen will find the bowl depth and gauge combination here worth specifying over a lighter-duty option. Homeowners doing a full kitchen renovation who want the workstation ledge system without trading bowl capacity for it will get both. Contractors sourcing for a client with a restaurant-style kitchen or a serious home cook should treat the 14-inch depth as the lead spec: it's the feature a standard workstation sink cannot match and this one is built around.
Does this sink require a special cabinet or cutout?
Undermount sinks like this one require a countertop material that supports undermounting — stone, quartz, and solid surface are common choices. The countertop fabricator should confirm the cutout dimensions against the actual sink before cutting. A standard sink base cabinet that accommodates the overall 23 by 18-3/4 inch footprint is the starting point.
What accessories are included in the PK1 kit?
The WS-33-PK1 ships with a stainless steel basket strainer, a bottom grid sized for this bowl, and Luster Pro care oil. Additional workstation accessories such as a cutting board, colander, or drying rack are sold separately and sized to fit the WS-series ledge.
Is the faucet included?
No. The -PK1 pack includes the sink, strainer, grid, and care oil only. A faucet is purchased separately. If you want a pack that includes a coordinating faucet, look for the -PK2 version in the workstation lineup.
How does a 14-inch deep bowl affect the plumbing rough-in?
A deeper bowl means the drain outlet sits lower in the cabinet than it would with a 9- or 10-inch bowl. Confirm the drain line height and P-trap clearance in the base cabinet before installation, particularly in existing kitchens where the plumbing was originally set for a shallower sink.
Depth, Gauge, and Ledge in One Undermount Package
The WS-33-PK1 brings together a 14-inch deep bowl, 16 gauge stainless, and an integrated workstation ledge in an undermount format — a combination that covers the needs of serious kitchen use from the first day it goes in.
