The plastic bottles in your recycling bin might just find their way into your bathroom in a glamorous new form, embodying artistic sophistication. Roca’s Stonex material, crafted from recycled PET resin, features prominently in the expanded Ohtake collection. This innovative line, hailed for its design-forward approach, includes a compact bathtub inspired by Japanese Ofuro soaking culture. Stonex not only provides warmth to the touch but is also resistant to discoloration and wear, ensuring a lasting pristine look. From humble beginnings in recycling bins to receiving accolades like the Red Dot award, the journey is impressive.
Rodrigo Ohtake’s Legacy of Sculptural Elegance
Rodrigo Ohtake, son of the renowned Brazilian architect Ruy Ohtake, designed this collection’s expansion with Roca. His contributions feature two distinct basins, both derived from hand-sculpted clay models. These basins, resembling calla lilies, veer away from traditional geometric designs, offering a more organic look with graceful design. Accompanying the bathtub, soy resin accessories like a side shelf and an adaptable entry step/stool emphasize sustainability. Rodrigo’s approach harmonizes material choice and aesthetics, crafting an environment where these decisions meld seamlessly.

Diverse Design Options and Rich Finishes
While inspired by similar botanical elements, the basins introduce unique interpretations. One basin serves as a shallow, elongated vessel with an elegant, curved form reminiscent of a leaf in motion, showcasing artistic refinement. The second is deeper, offering a bolder, rounded design. Both basins, though rooted in clay artistry, are available in a wide palette far beyond basic whites. They feature finishes in matt black, onyx, coffee, beige, and an exclusive terracotta, which is primarily available in Brazil or upon request.

The Ofuro-Inspired Bathtub
The Stonex bathtub captures the essence of traditional Ofuro baths with compact, steep sides designed for upright soaking and exceptional style. Integrated seating enhances the cocooning effect, prioritizing immersion over mere rinsing. Standard soy resin accompaniments such as a step and shelf complete the bathing ritual setup. Notably, Stonex retains heat upon contact, an understated yet crucial benefit for an enjoyable soaking experience.

A Legacy of Design Innovation
Following the passing of Ruy Ohtake in 2021, Rodrigo seamlessly continued the legacy, merging practices into the OHTAKE studio in 2022. Ruy’s notable contributions include over 420 projects, grounded in organic forms and inspired by nature. Meanwhile, the influence of Rodrigo’s grandmother, Japanese-Brazilian abstract artist Tomie Ohtake, adds depth to the family’s design ethos. This blend of Japanese heritage with Brazilian modernism and sustainable design principles enriches the collection, aligning with Rodrigo’s future-focused vision and artistic charm.
