If you've visited a spa or wellness centre in Germany, Austria, Switzerland, or the Netherlands recently, you may have encountered a scene that looks somewhere between performance art and group therapy: a person in white linen, wielding a towel like a conductor's baton, waving clouds of fragrant steam over a room full of silent, sweating people.
This is Aufguss — arguably the most sophisticated sauna ritual in the world, and one that's quietly spreading far beyond its Central European roots into the UK, North America, and Asia.
What Aufguss Actually Is
The word Aufguss is German for 'infusion' or 'pour.' At its most basic, it refers to the act of ladling water — usually infused with essential oils or herbal preparations — over the hot stones of a sauna stove to create a burst of steam (löyly, in Finnish).
But a proper Aufguss session is considerably more than a steam pour. It's a guided group experience led by a trained Sauna Master, typically lasting 15–25 minutes, combining multiple rounds of steam with choreographed towel work designed to distribute the heat and fragrance evenly around the room.
The towel work — the signature visual element of Aufguss — isn't ceremonial. It serves a specific function: the waving motion creates airflow that pushes the hot, fragrant steam from the ceiling down through the room, raising the perceived temperature for all participants and distributing the aromatherapy effect evenly. A skilled Sauna Master can control the intensity of the heat experience for the entire group through the pace and technique of their towel movements.
The Origins of Aufguss
While sauna bathing itself is ancient — particularly in Finland, where saunas have been a cornerstone of culture for thousands of years — the formalised Aufguss tradition as a performed ritual is largely a German and Central European development of the 20th century.
German sauna culture, distinct from Finnish sauna culture in a number of ways, developed the Aufguss as a social and sensory experience to be shared and guided. Where Finnish sauna traditionally emphasises personal contemplation and quiet, Aufguss is communal and theatrical — though no less serious in its pursuit of physical and mental restoration.
Today, competitive Aufguss — yes, this is a real thing — draws hundreds of participants across Europe, with national championships feeding into international competitions judged on technical skill, creativity, and the Sauna Master's ability to create a cohesive group experience.
What a Session Feels Like
If you've never experienced a proper Aufguss session, the closest analogy is a guided breathwork or meditation class — except the environment is 90°C, and the effect is considerably more intense.
A typical session begins with participants seated on the benches before the Sauna Master arrives. The stove has been brought to full heat. There's usually brief instruction for newcomers — the exits, the protocol for leaving if needed, what to expect.
The first pour happens quickly. The temperature in the room rises sharply. The Sauna Master begins the towel work, moving around the room, directing heat at different sections of the audience. The fragrance — eucalyptus, citrus, pine, or any of dozens of other preparations — fills the air. By the third or fourth pour, the experience is genuinely intense: a full-body heat load combined with powerful aromatherapy, guided by someone who knows exactly what they're doing.
Most sessions end with a theatrical final pour and a crescendo of towel work before the Sauna Master invites everyone to cool down. The contrast between the session's peak heat and the cold plunge or cool outdoor air afterwards is a significant part of the experience.
Why It's Growing Outside Europe
The wellness industry has expanded dramatically in the UK, North America, and Australia over the past decade, and with it, interest in traditional sauna culture — including its more sophisticated rituals.
Aufguss appeals because it turns the sauna from a passive, individual experience into a guided group ritual with a beginning, middle, and end. For people who find the passive nature of traditional sauna difficult to sustain, the structured social experience of Aufguss is a natural entry point. For experienced sauna practitioners, it adds a dimension of intensity and intentionality that solo sessions can't replicate.
Sauna businesses across the UK and North America are increasingly training dedicated Sauna Masters and running scheduled Aufguss sessions as centrepiece offerings. Nick Tettersell, voted the UK's top Sauna Master by the British Sauna Society, is among those who has helped raise the profile of the practice in Britain.
Preparing for Your First Aufguss
If you're planning to attend an Aufguss session, a few practical notes:
Hydrate well before you go. The heat intensity in a guided Aufguss is significantly higher than a standard sauna session, and you'll sweat considerably more.
Protect your head. The hottest air concentrates at the ceiling and rains down during the towel work — this is precisely the environment in which scalp heat and hair protection matter most. Experienced Aufguss practitioners invariably wear a proper wool sauna hat, both for comfort and for the ability to sustain the full session without the head becoming the limiting factor.
It's completely acceptable to leave if you need to. No reputable Sauna Master will object. Listening to your body is part of the practice.
And finally: settle in. An Aufguss session is not something to observe from a distance. Get to the top bench, close your eyes, and let the ritual do its work.
