The Retrofit Specialist: 30″ Narrow Topmount Sink

Maximize your washing space without compromising your countertop structure. Our 750x450mm Topmount Handmade Sink is specifically engineered with a slimmer 450mm width profile. This makes it the perfect solution for kitchens with narrower countertops or for renovation projects where preserving the existing backsplash and cabinetry is a priority.

Designed for Easy Replacement

Replacing an old sink can be a headache if the new model is too wide. This 750x450mm unit drops easily into most standard cutouts, and its 3.0mm Thick Mounting Deck offers two key benefits:

  • Structural Rigidity: Unlike thin replacement sinks that flex, our 3mm solid stainless steel rim provides a rock-solid platform for mounting heavy modern faucets.
  • Flaw Coverage: The robust rim sits flat and secure, effectively covering any rough edges or chipping left from the previous sink’s cutout.

Deep Capacity in a Slim Frame

While the footprint is compact, the performance is full-sized. The 230mm (9-inch) deep bowl [700x400mm internal] provides ample room to submerge large pots and stack dishes, keeping dirty items out of sight.

Handmade Quality

Upgrade from stamped builder-grade sinks to true craftsmanship. This sink features R10 Tight Radius corners for a contemporary rectangular look that maximizes bowl volume. It is fully soundproofed with heavy-duty pads and condensation-proof coating to protect your cabinets.


Wholesale Note: The 450mm width is a strategic inventory item. It captures sales from customers who simply cannot fit a standard 480mm or 500mm wide sink into their existing layout.
