Transform Your Ritual: The In-Wash® Ona Experience
Built upon Roca's industry-leading technology platform, the Ona Series focuses on a "Connected Life," bridging the gap between hardware and software. By integrating IoT capabilities, Roca ensures that your wellness settings follow you, configurable to the last detail through your smartphone.
Airtech™ Multi-Stream Wash
Utilising the next level of cleaning efficiency, the Ona seat offers Soft Front Wash (spraying from nine different sources) and Rear Wash with Multi-Stream. By mixing air into the water, the Airtech™ system provides a firmer yet more gentle cleaning result, using less water for a superior clean.
Coanda Effect Drying
Inspired by aerodynamic principles, the dryer nozzle directs airflow to follow the surface of the body precisely. This Coanda Effect ensures peak drying performance at any power level, significantly reducing the need for toilet paper and increasing post-wash comfort.
Roca Connect IoT
The Ona seat is a fully-fledged smart device. The Roca Connect app acts as a bridge, allowing you to create personal user profiles, schedule maintenance, program daily cleaning cycles, and monitor water consumption insights directly on your iOS or Android device.
Uncompromising Hygiene
Advanced self-cleaning technologies ensure your safety.
UV Light Sterilisation
The nozzle automatically rinses before and after use. For ultimate peace of mind, an integrated UV light kills 99.99% of bacteria, ensuring a sterile wash every time.
Quick Release Technology
Both the seat and lid can be removed with a single motion. This allows for deep cleaning of the ceramic bowl and seat hinges without obstruction, eliminating hidden dirt traps.
Integrated Descaling
Hard water is no match for the Ona. The easy-to-use descaling programme protects internal components from limescale build-up, ensuring long-term mechanical performance and reliability.
Roca is a global leader with nearly a century of heritage. Based in Spain and operating in 170 countries, Roca combines Mediterranean design with cutting-edge engineering. The In-Wash® series represents their commitment to making smart hygiene accessible to every household.
Important Compatibility & FAQ
Will the In-Wash® Ona seat fit my existing standard toilet?
No. The A804053S01 is engineered exclusively for hidden connections. It is ONLY compatible with three specific Roca Smart ceramic pans: the A347688000 (Smart Back-to-Wall), the A342689000 (Smart Close-Coupled), and the A34668B000 (Smart Wall-Hung). It will not fit standard or legacy Roca pans.
What does "Hidden Connections" mean?
Unlike retrofit bidet seats that require external water hoses and power cables plugging into the side of the seat, this model allows the water and electrical feeds to enter through the ceramic pan itself. The result is a completely cable-free, minimalist look identical to a standard designer toilet.
What is the "Coanda Effect"?
It is a principle of fluid dynamics where a jet of fluid (or air) follows a convex surface. In the Ona seat, this means the dryer air "sticks" to the skin rather than dispersing, ensuring faster and more comfortable drying efficiency.
Is this seat WRAS approved?
Yes. The Roca In-Wash® Ona is fully WRAS approved, ensuring it meets the stringent safety and water-quality regulations required for legal installation in UK homes.
