Floor Drain | 15cm x 15cm Square Matte Stainless Steel Drain with Anti-Backflow Non-Return Valve

The N330MATT is a modern 15cm x 15cm square floor drain constructed from high-grade SUS 304 stainless steel. Designed for minimalist aesthetics, it features a solid tile-insert or flat-panel cover and includes a specialized non-return valve to prevent the backflow of water, odors, and pests from the sewage system.

The Floor Drain represents a significant upgrade in both bathroom technology and design. This 15cm x 15cm unit is engineered from premium SUS 304 stainless steel, ensuring exceptional resistance to rust and corrosion in wet environments. The surface features a sophisticated matte finish, providing a contemporary, non-reflective look that resists fingerprints and water spots.

The defining feature of the N330MATT is its Anti-Backflow Mechanism. The drain assembly includes a mechanical non-return valve that remains closed by default, opening only when water pressure from above is applied. This prevents “back-flooding” during heavy rain or plumbing surges and acts as a permanent seal against sewer gases and insects. The kit also includes a secondary internal strainer and a removal hook for effortless maintenance. Its large 15cm profile is perfect for high-end residential showers and modern wet rooms.
