Roca's Bathroom Designs Transform Recycled PET Bottles into Luxury
Sustainable materials meet sculptural bathroom elegance
1From Waste PET to Luxury Designs
Roca's Stonex material is crafted from 100% recycled PET resin. The Ohtake collection represents the most design-forward iteration of this material to date. Inspired by Japanese Ofuro culture, the compact bathtub features a warm-to-the-touch surface resistant to wear and discoloration. Awarded the Red Dot, it proves sustainability can coexist with luxury bathroom experiences.
2Brazilian Design Heritage
Rodrigo Ohtake, son of legendary architect Ruy Ohtake, expanded the collection. The two new basins originated from hand-sculpted clay models, resulting in calla lily-inspired forms rather than conventional flat geometries. Complementary soy resin accessories (including a side shelf and dual-purpose entry stool) complete the holistic design vision blending sustainability with functionality.
3Material Innovation
Stonex maintains ambient heat upon contact, differing from traditional ceramic tubs. Surfaces made from recycled PET resist fading and wear while soy resin accessories reduce carbon footprint by 60% compared to fossil-fuel plastics. The material composition includes 8-10 recycled bottles per square meter of product surface area.
4Japanese-Brazilian Fusion
The Ofuro-inspired tub features compact, steep-sided dimensions for upright soaking. Basin curves reflect abstract influences from Rodrigo's grandmother Tomie Ohtake's artwork. Three generations of design philosophy converge in these pieces - combining Japanese heritage, Brazilian modernism and contemporary sustainable practices.
5Color and Texture Options
Beyond standard whites, the collection offers matte black, onyx, coffee and exclusive Brazilian terracotta finishes. The terracotta variant particularly showcases handcrafted ceramic qualities. All surfaces feature specially treated matte finishes that resist water spots while providing tactile warmth uncommon in recycled materials.
6Design Accolades
In 2025, the collection won both iF Design Award and Red Dot honors, plus 'Best in Show' at Brazil's Expo Revestir. Juries praised how material innovation balanced with aesthetic appeal. These recognitions demonstrate that sustainable design is judged by execution as much as intention, setting new benchmarks for eco-conscious luxury.
7Global Availability
The collection launched worldwide through Roca's premium showrooms and building material retailers. Particularly popular in European and Asian luxury residential projects, each product repurposes 8-10 PET bottles per square meter. Roca announced plans to incorporate 40% recycled materials across all product lines by 2026.
8Future of Sustainable Design
Roca's Ohtake collection disproves the notion that recycled materials can't deliver premium aesthetics. This approach has potential to shift consumer perceptions about eco-design being purely functional. Backed by three generations of design legacy, the project demonstrates how waste materials can transform into high-end products without compromising quality or visual appeal.
