Description

Experience the perfect blend of tactile precision and industrial style with the Arno Classic Square 4-in-1 Brushed Gunmetal Instant Boiling Water Tap. This robust system replaces the need for a kettle and bottled water, delivering standard hot, cold, filtered 98°C boiling water, and fresh filtered drinking water from a single, masterfully crafted fixture.

Distinguished by its mechanical dual-lever design and premium diamond-cut knurled handles, this tap offers a satisfying, physical interaction that touch screens simply cannot match.

Why Choose the Arno Classic Square Gunmetal?

  • Industrial Tactile Control

    For those who appreciate craftsmanship, the Classic mechanical handles feature a textured knurled finish. This not only looks stunning in the Brushed Gunmetal colour but provides a secure, non-slip grip for precise water dispensing. Prefer a digital touch screen instead? View the modern Arno Square 4-in-1 Gunmetal Tap.

  • 4-in-1 Hydration Station

    Streamline your kitchen and your health. With a dedicated lever for filtered cold water, you have instant access to pure, great-tasting hydration, helping you reduce plastic waste. Read more on improving water quality at home.

  • Durable & Practical Finish

    The Brushed Gunmetal finish is the ultimate choice for busy kitchens. Its muted, metallic tone effectively hides water spots and fingerprints, ensuring your tap remains a sophisticated centrepiece with minimal maintenance.

  • Mechanical Safety Lock

    Safety is built into the mechanism. The boiling water handle utilises a push-and-turn spring lock, making it impossible for children to accidentally dispense boiling water.
