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.
Embrace the best of both worlds: the tranquillity and privacy of your own wellness space and the opportunity to explore our extensive public baths with a wide range of saunas and wellness baths. Both private saunas have a unique combi sauna with infrared therapy, a steam bath and a Jacuzzi. In our public baths, you can also take part in free daily Aufguss, scrubbing and Tibetan singing bowl sessions, as well as our wonderful Mindful Moments on Wednesdays.
Good to know: our public baths are divided into two separate areas. In Aquarius, you enjoy wellness naked and in Sabai, you do so in swimwear.
