The Oversized Retrofit Solution: 750x520mm Topmount Sink

When standard sinks aren’t wide enough to cover your old countertop cutout, our 750x520mm Extra-Wide Topmount Sink is the answer. With a generous 20.5-inch (520mm) width, this model provides superior coverage and a substantial, high-end presence on deeper countertops.

Why 520mm Width?

Standard sinks are typically 480mm or 500mm wide. Our 520mm model offers specific advantages:

  • Renovation Coverage: If replacing an old, oversized sink, this wider rim ensures the new sink completely overlaps the existing hole, saving you the cost of replacing the entire granite slab.
  • Spacious Faucet Deck: The extra width allows for a roomy faucet deck area, easily accommodating large faucet bases and accessories without crowding the bowl.

3.0mm “Rock-Solid” Construction

Engineered for durability, the 3.0mm thick stainless steel deck sits flat and secure against the countertop.

  • Stability: Eliminates the “flex” found in thinner sinks when using heavy commercial-style pull-down faucets.
  • Aesthetics: The thick, machined edge provides a premium, built-in look that elevates the kitchen’s overall design.

Handmade Precision

Inside, the basin features R10 Tight Radius corners, combining the sharp look of zero-radius sinks with the easy cleaning of rounded corners. The 230mm (9-inch) deep bowl [700x410mm] handles your largest cookware with ease.


Wholesale Note: Stocking the 520mm width SKU positions you as a “solutions provider” for contractors dealing with non-standard cutouts or custom deep cabinetry.
