The Classic Multitasker: 31″ Topmount Double Bowl Sink

Bring efficiency and balance to your kitchen with our 780x500mm Topmount Double Bowl Sink. Designed for homeowners who prefer the classic “wash and rinse” workflow, this sink features two equally sized basins, allowing you to multitask without cross-contamination. It fits perfectly into standard 31-inch cabinet cutouts, making it an easy upgrade for existing kitchens.

Symmetric 50/50 Versatility

The dual 350mm wide basins offer a practical separation of tasks:

  • Basin 1: Fill with hot soapy water for soaking and scrubbing dishes.
  • Basin 2: Keep clear for rinsing off foam or air-drying washed cutlery.
  • Hygiene: Perfect for defrosting raw meat in one bowl while washing vegetables in the other.

3.0mm “Anti-Flex” Construction

Standard topmount double sinks often suffer from structural weakness in the middle bridge or faucet deck. We engineered this model with a 3.0mm thick solid stainless steel deck.

  • Rock-Solid Support: The extra thickness provides rigid support for the faucet, preventing the annoying “wobble” often seen in thinner pressed sinks.
  • Perfect Seal: The flat, heavy rim creates a tight seal against the countertop, preventing water seepage.

Handmade Precision & Convenience

Unlike old-fashioned rounded pressed sinks, this handmade model features R10 Tight Radius corners, maximizing the flat bottom area of each bowl to prevent glasses from tipping over. It comes pre-drilled with a secondary accessory hole, ready for a soap dispenser or filtered water tap.


Wholesale Note: This model shares the exact same 780x500mm cutout size as our Single Bowl model (Item #16). Stocking both gives your customers the flexibility to choose their preferred bowl configuration without changing the countertop plan.
