Ocean Spa Fuua
Come for the open-air sea views and the room to make an afternoon of it: Fuua pairs several baths with lounges and sauna facilities. It is a premium-priced day spa, and some areas are scheduled to close for renovation from September 28, 2026, so check the operator's latest notices before visiting.

Spring & water temperature

- Spring source
- Ocean Spa Fuua's own spring; the current official site does not publish an individual source number.

- pH
- Not published.
- Flow rate
- 155 L/min.
- Water handling
- The facility explicitly describes one open-air bath as flowing spring water. Treatment details for the other pools are not published pool by pool, so they should not all be described as free-flowing.
Bathing indications
The facility lists general bathing indications for the spring. They are not a promise of treatment.
Exact water-treatment details for each pool are not published. Renovation dates and access restrictions may change; check the current facility notice.
How to read a bath profile
Spring-source temperature and actual bathing temperature are kept separate. Each score is shown independently for comparison rather than collapsed into one overall score.
