Free entry with 2hrs/2p private sauna
Book one of our private saunas for 2 hours for 2 people from 10/06 to 10/09/2025 inclusive and get free entry to our public baths for the rest of the day.
This gives you a double wellness treat: a peaceful, totally private experience in your own wellness space and the opportunity to explore our extensive public baths with a wide variety of saunas and wellness facilities.
Both private saunas have a unique combi sauna with infrared therapy incorporated in a traditional Finnish sauna, a steam bath and a Jacuzzi.
Useful to know: our public baths are divided into two separate areas. In Aquarius, you can enjoy wellness in the nude; in Sabai, you do so in swimwear.
