About Cascade 連體座廁

Cascade係一款為家庭浴室而設計嘅連體座廁。一條流暢嘅斜切邊緣由廁盆延伸至水箱，賦予Cascade清晰嘅視覺特色，靈感源自水嘅流動。廁板兩側外緣設有提手位，令雙手可以避開較唔衛生嘅位置。隱藏式排污管道安裝時冇好多其他型號常見嘅外露孔位同塑膠蓋，令安裝更加簡便。Cascade採用陶瓷製造，每次沖水只需4.8公升。其造型亦與同系列嘅其他浴室產品互相配合。

Production Technology: Cascade was designed and is manufactured in Colombia. Cascade is crafted with Corona’s commitment to sustainability and innovative manufacturing. Approximately 12-17% of the toilet's materials are sourced from recirculated breakage during the production process, contributing to resource efficiency. In addition, 78% of the water used in production is recirculated. Moreover, it is backed by Corona’s lifetime warranty, reinforcing its durability and long-term serviceability.
Design Challenge: Cascade aimed to revitalize our high-end product lineup by offering a solution with greater value. We faced the challenge of creating a design that stood out from generic market offerings while maintaining broad appeal; a design that also needed to fit seamlessly with the rest of the Cascade product line. Moreover, we had to reinvent our manufacturing techniques for this concealed trapway toilet, as we wanted to incorporate a separate plastic trapway to simplify installation.
Research: Our research combined an ethnographic study of Latin American families with benchmarking of current market trends. This approach aimed to balance user preferences in aesthetics and usability while differentiating our product from existing offerings. Key findings revealed that users prefer minimal contact with toilets for hygiene reasons, struggle with installing toilets featuring hidden trapways, and feel the market is dominated by generic and imported designs.
Inspiration: The Cascade toilet draws inspiration from the sculpting force of a waterfall, embodying both strength and grace. Its flowing, chamfered edge, which extends from the bowl to the tank, reflects a continuous journey that mirrors the natural movement of water. This "Flowing Line" design creates a strong visual identity, moving away from the softened forms typical in the market to establish a bold yet refined presence in the bathroom.
Project Duration: The project started in June 2019 in Medellin, Colombia and due to the Covid-19 pandemic, development ended in 2023. It was released in Colombia in 2024.
Operation Flow: Cascade prioritizes user-friendliness in every aspect. From its intuitive installation process to the innovative seat design, every element enhances the user experience. The seat features cleverly designed tabs on the outer edges, which keep hands away from less sanitary areas, ensuring better hygiene and comfort. Additionally, the concealed trap-way installation is simplified, avoiding the typical unsightly holes and plastic caps seen in other models, making setup smooth and efficient.
