The Ultimate Entertainer’s Centerpiece: 36″ Trough Sink

Elevate the luxury of any kitchen island or wet bar with our 36-Inch Undermount Trough Sink. Featuring a striking narrow profile (920mm x 204mm), this basin is designed not just for washing, but for high-end entertaining. It is the ultimate statement piece for homeowners who love to host, instantly transforming a standard kitchen counter into a professional-grade cocktail station or oyster bar.

From Prep Station to Ice Trough

The unique shallow depth (120mm / 4.7″) and elongated design make it incredibly versatile:

  • Party Mode (Ice Trough): Fill the basin with crushed ice to chill bottles of champagne, craft beer, or fresh seafood right on the island where guests gather.
  • Mixologist Mode: Utilize the included modular bar accessories. The custom-fitted perforated trays and cross-dividers act as a functional staging area for garnishes, washed glasses, and bar tools.
  • Secondary Prep: Perfect as a supplementary sink for washing delicate fruits or herbs without interfering with the main kitchen sink.

Architectural R0 Zero-Radius Design

Unlike standard sinks with curved corners, this trough sink is engineered with true R0 (Zero Radius) 90-degree corners. Meticulously handmade-welded, these sharp, clean lines provide a striking, contemporary commercial aesthetic that pairs flawlessly with modern stone countertops and minimalist cabinetry.

Premium PVD Finishes & Durability

Crafted from heavy-duty 1.2mm (18-Gauge) SUS304 stainless steel, the sink is built to withstand the clinking of heavy glass bottles and barware. Upgrade to our advanced Nano PVD Technology (Available in Gold, Gunmetal, and Black) for an ultra-durable, scratch-resistant surface that repels water and makes a bold design statement against dark marble or quartz countertops.


Wholesale / Design Note: Trough sinks are a high-margin niche product highly sought after by custom home builders and interior designers. They are often paired with secondary bar faucets or installed at the rear of deep kitchen islands.
