Sauna Aufguss Etiquette: Why You Never Pour Water Without Asking

You are sitting on the upper bench, the room is calm, and someone grabs the ladle and empties it onto the stones. A second later a wave of steam hits everyone at once. That is exactly the moment this rule exists for: in a shared sauna, the water on the stones belongs to the whole room, not to one person.

What is an Aufguss?

Aufguss is German for “infusion” or “pour”. It is the classic heat ritual of saunas in Germany, Austria and Switzerland: a sauna master pours water, usually mixed with a scent such as birch, eucalyptus or citrus, onto the hot stones. The steam rises to the ceiling, and the sauna master then waves a towel to push the hot, moist air through the room and toward each guest.

A typical Aufguss lasts around 10 to 15 minutes and runs in about three rounds, each one a little more intense than the last. Public saunas post the times on a board, often on the hour or half hour. The thermometer barely moves, but the jump in humidity makes the room feel much hotter. That is why the ritual is planned and announced instead of left to whoever reaches the bucket first.

In Finland the steam itself is called löyly, and throwing water is part of every sauna, not a show. The customs are different, but one habit is the same everywhere: you ask first.

Can you pour water yourself? It depends on the sauna

Where	Can you pour?	What to do
Public sauna in Germany, Austria or Switzerland	Usually no	Wait for the scheduled Aufguss. Only pour where a sign allows self-infusion (Selbstaufguss), and ask everyone in the room first.
Sauna in Finland	Usually yes	Ask the room before you throw, for example “Is more löyly okay?”, then pour one ladle at a time.
Gym or hotel sauna in the US	Often not allowed	Many gym heaters are not made for water. Look for a bucket and a sign: no bucket usually means no water.
Infrared cabin	Never	There are no stones. Water on infrared panels can damage them.
Your own home sauna	Your call	Ask your guests before each round and follow your heater’s manual.

Why pouring without asking is rude

• Everyone gets the heat at once. One ladle changes the room for every person on the bench, not just for you.
• Someone may be at the end of their round. A sudden wave of steam can push a person who was about to leave past their limit.
• Too much water stings. A full ladle on very hot stones sends up a burst of steam that can sting the skin and eyes, especially on the upper bench.
• It breaks the ritual. During an Aufguss the sauna master plans how the heat builds over the rounds. Extra water throws that off for everyone.

Aufguss etiquette: 7 rules

1. Arrive before it starts. Once the door closes, most saunas do not let anyone in until the ritual is over.
2. Sit fully on your towel, feet included. No sweat on the wood.
3. Stay quiet. The Aufguss is one of the few moments when even a whisper is out of place. More on that in our guide Is it rude to talk in the sauna?.
4. Choose your bench. The heat collects at the top. For your first Aufguss, sit on the lower bench.
5. Leave if you need to. Feeling dizzy or too hot is always a reason to go, whatever the rules say. If you can, leave between rounds, quietly, and close the door quickly behind you.
6. Hands off the ladle and bucket. During the ritual they belong to the sauna master.
7. Say thank you. In Germany, a short round of applause for the sauna master at the end is common.

After the Aufguss, cool down step by step: fresh air, a cool shower, then a proper rest. Here is what to do after the sauna so the heat does not catch up with you later.

How to do an Aufguss at home

Your home sauna is the one place where you set the rules. A simple routine that works:

1. Heat the sauna fully. Many people like a traditional sauna somewhere around 80–90 °C (175–195 °F) for an Aufguss. See our guide to the right sauna temperature.
2. Prepare the bucket. Fill it with water and add a scent made for sauna water, at the dose on the label.
3. Round one: one ladle, poured slowly over the stones. Wait until the steam has settled.
4. Round two: two ladles, a few seconds apart. If you like, wave a towel in slow circles to bring the heat down to the bench.
5. Round three: two or three ladles for the peak, then sit still for a minute or two.
6. Cool down and rest. Fresh air, a cool shower, and at least as long resting as you spent in the heat. The free sauna timer keeps track of the rounds for you.

Only pour on the stones, never on the heating elements, and check your heater’s manual first: most wood-burning and traditional electric heaters are built for water, but some compact heaters are not. If you are unsure what steam does to the feel of the room, read dry sauna vs. wet sauna.

Never pour pure essential oil on the stones

Undiluted essential oil does not belong on hot stones. It can burn on the surface, give off harsh fumes that sting the eyes and airways and, in the worst case, catch fire. Use scents made for sauna water, mix them into the bucket and keep the dose low. If someone in the room does not like strong scents, plain water is the polite choice.

FAQ

What does Aufguss mean?

It is German for “infusion” or “pour”: water poured onto hot sauna stones, usually as a guided ritual in which a sauna master waves a towel to spread the heat.

Can I leave during an Aufguss?

Yes. Your health comes first. If you can, wait for the short break between rounds and leave quietly so the heat stays in the room.

Can I pour water on the stones in a gym sauna?

Only if there is a bucket and the sauna allows it. Even then, ask the people inside before you pour.

Yes. During the ritual everyone stays silent. Before and after, a few quiet words are fine in most saunas.

Is an Aufguss right for everyone?

The jump in humidity is intense. If you are pregnant or have a heart or blood pressure condition, ask your doctor before you try it, and start on the lower bench.
