Recovery & Social Wellness
Wind down.
And arrive.
Our Fire & Ice zone is made for recovery: warmth that loosens the body, cold that clears the mind, and rest that lets both settle. Stay entirely with yourself — or share the moment with friends and talk over tea in the lounge afterwards.
- 01
Recovery for the body
Finnish sauna, infrared sauna, two ice baths (0–2 °C and 6–8 °C), red light and massage chairs — alternate as often as you like.
- 02
Calm for the mind
No programme, no pressure. Quiet room, soft light and time that's just yours.
- 03
Social wellness
Come alone or with friends. Afterwards: tea, a smoothie and conversation in the lounge.
OUR OFFERINGS
Two hours just for you: sweat, plunge, feel it settle — at your own pace, until body and mind come to rest.
WHAT IS A FREE FLOW?
You don't book a single station – you book 120 minutes for the whole Fire & Ice zone. The Finnish sauna up to 95 °C and infrared sauna at 65–75 °C are both included in Free Flow at no extra charge, alongside both ice baths, red light, massage chairs and rest area, at your own pace.

- 120 minutes
- Your time starts at your booked slot, changing included.
- Both saunas
- Finnish and infrared sauna — no separate booking or extra charge.
- Your rhythm
- Switch and repeat as you like, on your own or guided.

EQUIPMENT – BRIEFLY EXPLAINED
Which towel do I need?
Ideally two: a large towel to sit or lie on in either the Finnish or infrared sauna, and a second one to dry off after the ice bath and shower. A sauna towel or a normal bath towel is perfectly fine – a bathrobe is nice, but not required.

CONTRAST THERAPY — THE PRINCIPLE
Heat dilates vessels, cold narrows them: the planned alternation of Finnish sauna, infrared sauna and an ice bath at 0–2 °C — also called contrast bathing or hot-cold exposure — trains thermoregulation and circulation. Two to four rounds with rest phases in between is a sensible range.
