Initial Challenge
The bathroom sector was facing growing pressure to reduce environmental impact and improve sustainability without compromising on comfort or aesthetics. Our challenge was twofold:
-
-
Reduce potable water consumption, particularly in toilet flushing
-
Optimize space in compact urban bathrooms, especially in small apartments
-

The Method
As part of Roca’s innovation process, we carried out in-depth cross-disciplinary research and ideation. Our approach was structured around a 9-point insight framework:
-
Customer: We explored user behaviors around water usage, hygiene habits, and expectations for modern bathroom experiences
-
Potential Target Group: Young urban dwellers and environmentally conscious homeowners in space-constrained living environments
-
Different Types of Needs: Functional (space-saving, easy maintenance), emotional (feeling responsible, living consciously), and social (aesthetic status of home fixtures)
-
Competitor Companies: Audited direct competitors to identify gaps in eco-efficiency and integrated design offerings
-
Internal Competition: Evaluated Roca’s existing portfolio to ensure the new concept wouldn’t cannibalize current products
-
Previous Unsuccessful Products: Reviewed legacy designs and failed water-saving concepts to learn from past limitations
-
Technology / Materials: Researched innovations in water filtration, ceramic technologies, and integrated plumbing systems
-
Category of the Seed: Positioned W+W as a hybrid product—between sanitaryware and eco-home innovation
-
Business Potential: Assessed viability based on production feasibility, market interest, and alignment with Roca’s sustainability goals
Ideas and User Need Collection:
- Multidisciplinary workshop sessions
- Fast model making and testing the principals:
The Solution
The outcome was W+W, a first-of-its-kind product that combined a washbasin and toilet into a single, space-saving unit with a built-in water recycling system. Key features included:
-
Greywater reuse system: Used water from the sink is filtered and reused for flushing the toilet
-
Space-optimized L-shape: Designed for small bathrooms, the vertical layout fits neatly into corners or narrow spaces
-
Award-winning aesthetics: Modern design language blending seamlessly with premium bathroom interiors
My Involvement
I contributed to the project as a member of Roca’s Innovation Lab, with responsibilities including:
-
Conducting structured research using the 9-point insight framework
-
Facilitating ideation workshops and helping define product direction
-
Design development: Sketching, mockups, early-stage prototyping
-
Cross-functional collaboration between R&D, engineering, and product marketing teams
W+W has since become an iconic sustainable product in Roca’s portfolio—recognized for its innovation in water efficiency, user-centered design, and compact living solutions.
