The Perfect Square: 17″ Deep Bar & Prep Sink

Add the finishing touch to your kitchen island or entertainment area with our 440x440mm Square Undermount Sink. Designed with perfect symmetry, this 17-inch basin offers a clean, geometric aesthetic that complements modern minimalist designs. While compact in footprint, it delivers full-sized performance.

Extra-Deep 9-Inch Basin

Most bar sinks on the market are shallow (6 or 7 inches), leading to frustrating water splashes on your countertop. Our model features a commercial-grade 228mm (9-inch) depth.
The Benefit: You can wash tall wine glasses, fill deep pitchers, or rinse produce vigorously without worrying about splashing water onto your guests sitting at the island.

Versatile Application

This compact square sink is the ultimate multitasker for luxury homes:

  • Prep Station: Install it on the kitchen island to create a dedicated zone for washing vegetables, keeping your main sink free for dirty dishes.
  • Wet Bar / Coffee Bar: The perfect size for rinsing cocktail shakers or dumping coffee grounds.
  • Compact Living: An excellent primary sink for Tiny Homes, RVs, or Studio Kitchenettes where space is at a premium.

Handmade Quality

Constructed from premium 1.2mm (18-gauge) SUS304 stainless steel, this sink is built to last. The interior features R10 Tight Radius corners for a sharp look that is easy to wipe clean. The bottom is engineered with X-grooves for rapid drainage and equipped with sound-dampening pads to ensure quiet operation.


Wholesale Note: The “Perfect Square” shape allows for consistent cutout templates and easy installation. It is a top-selling add-on item for kitchen cabinet packages.
