The Design
About Cascade 一体型トイレ
Cascade（カスケード）は、ファミリーバスルーム向けにデザインされた一体型トイレです。ボウルからタンクへと流れるように連続する面取りエッジが、水の動きから着想を得た明快な視覚的アイデンティティを生み出しています。便座の外縁部にはタブが設けられており、衛生面で気になる箇所に手を触れずに操作できます。隠蔽型のトラップウェイを採用し、他の多くのモデルに見られる目に見える穴やプラスチックキャップを用いずに設置できるため、施工が簡素化されます。Cascadeは陶器製で、1回の洗浄water使用量は4.8リットルです。またそのフォルムは、同シリーズの他のバスルーム製品とも調和します。

- 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.
