Frequently Asked Questions

Do I need a wall frame for this model?

Yes. This is a "Wall-Hung" model, which means it must be mounted onto a concealed frame (like a Geberit Duofix, Grohe Rapid SL, or TOTO frame) that is bolted into the floor or wall.

Does the Roca In-Wash ONA require electricity?

Yes. The smart bidet functions (washing, drying, UV light, seat sensor) require a standard mains electrical connection. The connection point should be positioned behind the toilet according to UK electrical safety zones.

How do I control the toilet without the App?

While the App offers deep customization, the toilet comes with a sleek magnetic Remote Control for everyday use. Additionally, there is a simplified Side Knob on the ceramic itself for basic wash and dry functions—perfect for guests.
