As an eco-friendly smart toilet, the Zen series leverages intelligent dual-flush and adaptive flush cycles to consume under 3 liters of water per flush without compromising hygiene. Its modular design—with stainless-steel inserts and recyclable materials—ensures “like-new” performance for years and enables extensive end-of-life reuse, while sensor-driven, energy-efficient heating and ventilation cut power usage by up to 40 %, and local assembly minimizes the CO₂ footprint from start to finish.
