About Cascade One Piece Toilet
Cascade is a one piece toilet designed for family bathrooms. A flowing chamfered edge runs from the bowl to the tank, giving Cascade a clear visual identity inspired by the movement of water. The seat has tabs on the outer edges, so hands stay away from less sanitary areas. The concealed trapway is installed without the visible holes and plastic caps found on many other models, which simplifies setup. Cascade is made of vitreous china and uses 4.8 litres per flush. The form also matches the other bathroom products of the same line.
The Cascade One Piece Toilet by Lucas Restrepo Velez represents a significant contribution to the evolving discourse around sanitary ware as a category deserving genuine design attention rather than mere functional specification. This work emerges from a contemporary practice that treats the bathroom fixture as an opportunity for formal invention and material celebration, participating in a lineage of industrial design that recognizes everyday objects as worthy vehicles for aesthetic consideration. The integration of cistern and bowl into a single monolithic form speaks to broader movements within product design toward visual simplification and manufacturing efficiency, yet the specific articulation here transcends mere reduction, achieving instead a sculptural presence that rewards sustained attention. The trapezoidal profile of the tank housing demonstrates sophisticated understanding of how geometric discipline can coexist with ergonomic accommodation, while the elongated bowl projects with a confidence that suggests careful consideration of both use and visual impact. Technical accomplishment manifests throughout in the quality of the ceramic surface, the precision of the seaming between components, and the thoughtful detailing of the seat and lid assembly. The recessed sculptural void carved into the tank's rear elevation introduces formal complexity while potentially serving practical installation requirements, demonstrating how functional constraints might be transformed into design opportunities. The chromatic restraint of the pure white glaze speaks to traditions of ceramic purity while aligning with contemporary preferences for clean, light-reflective bathroom environments that suggest hygiene and spatial expansiveness. One might consider how the side elevation presented here, rather than the more conventional three-quarter view, invites appreciation of the design as architectural profile, encouraging viewers to read the object as they might a building section or furniture elevation, attending to the rhythm of projection and recession, solid and void.

- 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.
- 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.
- 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.
