Your First German Therme Visit, Step by Step

Part of The German Sauna Guide — built from venues’ published house rules, not from a personal visit.

Most English-language pages about German saunas tell you the rules. Almost none tell you the order — what actually happens between walking through the door and walking back out, and where a first-timer is most likely to stand still looking lost. That gap is the whole point of this page.

The sequence below is the one that both of the house rules we worked from describe, and it is what regulars do without thinking about it.

Where this sequence comes from

This page is assembled from two published sets of German house rules: Therme Erding’s Haus- und Badeordnung, the version in force since 23 February 2026, and the Saarland Therme Haus- und Badeordnung. Where they differ, we say so.

We have not tested any of this in person and this is not medical advice. House rules are venue-specific: the signage at your entrance overrides anything here. Check your own venue’s Hausordnung before you travel — every large Therme publishes one.

Before you leave: what goes in the bag

Two venues, two slightly different kit lists, and the overlap is what you should pack. Saarland Therme names its requirement explicitly: swimwear, a towel, a large sauna towel, bathing shoes and a bathrobe. Erding’s sauna rule is about size rather than count — the towel under you has to cover your entire body including your feet.

• A large sauna towel. This is the one people get wrong. It goes under you, and it has to be long enough for your feet. A compact travel towel does not qualify.
• A second, ordinary towel for drying off, so you still have something dry at the end.
• A bathrobe. Not optional at either venue once you leave the cabin — including the restaurant and the rest areas.
• Bathing shoes. Saarland Therme requires them outside the sauna cabin; Erding bans street shoes from the barefoot areas. Flip-flops do the job.
• Swimwear. You will not wear it in the sauna, but the thermal pool side of the same building normally requires it.

Full list, including the towel dimensions worth checking before you fly with hand luggage, on the what to bring page.

Step 1 — the door: check the age limit before you book

This catches families out more than anything else. Saarland Therme is 18 and over, with a family day on Wednesdays as the exception. Therme Erding puts the sauna world and the Vitaloase at 16 and over, while the pool half of the same building is full of children.

There is no national rule here. It is set per house, it is published, and it is worth five minutes before you book a family day out.

Step 2 — the wristband, and how you pay

You are given a wristband with a locker key and a transponder in it. It is also your wallet: food, drinks and anything you buy inside are charged to it and settled at the exit rather than at the bar. Erding requires you to keep it on your body for the whole visit and charges a flat €45 if you lose it.

Practical consequence: you do not need cash inside, and you do need to keep an eye on what you are spending, because the total only appears when you leave.

Step 3 — the locker, and the phone stays in it

This is the step visitors are least prepared for. Saarland Therme requires mobile phones to be switched off and all camera-capable devices left in the locker, and prohibits phone and tablet use in the entire facility — it even names smart glasses. Erding prohibits smartphones, tablets and any recording device in the textile-free area, plus any photography or filming.

So there is no scrolling between rounds. Locals bring a book, and larger houses have reading lounges built for exactly that. Bring one, or plan on three or four hours of not looking at a screen — which, honestly, is a large part of why the whole thing works.

Step 4 — shower, and then dry off

Everyone knows about the shower. Both venues also require thorough washing before you use the facilities — Saarland Therme adds that soap is only for the showers, and that shaving and hair dyeing on site are not allowed.

The half people miss is the drying. Erding requires guests to clean themselves and dry off before use. Wet skin cools you instead of letting you sweat, and water dripping onto the benches is precisely what the towel rule exists to stop.

Step 5 — read the signs: Textil or textilfrei

Large German Thermen are split into two worlds in the same building. The thermal pool area is Textil: swimwear on, normal spa day. The sauna area is textilfrei: swimwear off inside it.

Both venues go out of their way to say that textile-free is not the same as a naturist resort. Saarland Therme writes that the sauna area “is not a classic FKK facility”; Erding says the same thing in its own words. The rule is narrow: undressed in the cabin, covered everywhere else.

If the textile-free half is not for you, the pool side is a complete visit on its own and nobody thinks anything of it.

Step 6 — the round itself

Inside the cabin, sit or lie on your large towel so that no part of your skin touches the wood. Saarland Therme states that requirement directly; Erding specifies the towel must go under the whole body including the feet. Everything else in the cabin is custom rather than rule:

• Higher benches are hotter, lower benches cooler. Start low.
• A round runs roughly 8 to 15 minutes — until it stops being pleasant, not until a clock says so.
• Quiet. Both venues require it in the sauna areas, and it is enforced socially long before staff get involved.
• Sit up for a moment before you stand. Standing straight out of a hot bench is how people get dizzy.
• Do not pour water on the stones. Only staff perform an Aufguss, and bringing your own essences is prohibited at both venues.

Step 7 — the cool-down, in the right order

Cold shower first, then the plunge pool. Therme Wien states that order explicitly in its own sauna rules and keeps its plunge pools at 18 °C. Rinsing first is partly hygiene and partly so the cold is survivable rather than a shock.

Then air. Outside if the venue has a terrace, which most do, regardless of the season.

Step 8 — the rest, which is the part people skip

Rest for about as long as the round lasted. This is where the effect of the whole exercise actually lands, and it is the step first-timers cut because it feels like doing nothing.

Two rules apply here that are easy to trip over. Saarland Therme requires a bathrobe or towel in the rest areas and that you are dried off before using the furniture. And loungers may not be reserved — at both venues, draping a towel over one to claim it for the afternoon is explicitly not allowed, and staff may remove whatever was left there.

Step 9 — rounds two and three

Two to three rounds is a normal visit. The second is usually the best one; by the third most people are done. There is no merit in more, and both venues note that only healthy people should be using the saunas at all — if you are pregnant, on blood-pressure medication or have a heart condition, that question is for your doctor.

Alcohol before the sauna is prohibited outright at Erding, which also reserves the right to refuse entry to anyone drunk. Heat and alcohol both lower blood pressure; that rule is about safety, not manners.

Step 10 — eating in between

There is almost always a bistro inside the sauna world, and you go in a bathrobe. Erding requires the robe or towel in its food and drink areas; Saarland Therme requires it in gastronomy and rest areas and adds that you must be dried off first. Therme Wien words it as house etiquette — “Essen mit Stil”, visit the Sauna-Bistro in a bathrobe.

Vienna also carves out the one phone exception we found anywhere: calls are permitted in the Sauna-Bistro and nowhere else.

Step 11 — leaving, and the clock nobody mentions

Bathing time ends before closing time, and the gap is venue-specific. Erding requires the thermal, sauna, slide and wave areas to be vacated 20 minutes before the building closes. Saarland Therme sets it at 30 minutes.

Add showering and dressing and you should be out of the water a good 45 minutes before the doors close. If you overrun a booked tariff you pay the difference at the exit, on the same wristband.

So how long does a first visit take

Three rounds with a proper cool-down and rest after each is roughly two and a half hours of actual sauna, plus arrival, showering, eating and dressing. Budget four hours and do not book anything immediately afterwards — you will not want it.

Frequently asked questions

Do I have to be naked the whole time?

No. In the textile-free sauna area you are undressed inside the cabin and required to cover up with a robe or towel outside it, including the rest areas and the bistro. Both venues state in their own rules that this is not a naturist facility.

Can I keep a towel wrapped around me in the cabin?

Generally yes, and many people do. What matters is what is under you: a towel large enough that no skin touches the wood, feet included.

Really no phone?

Really. Saarland Therme requires camera-capable devices to be left in the locker and bans phone use throughout the facility; Erding prohibits phones, tablets and recording devices in the textile-free area. Bring a book.

What if I get it wrong?

Someone tells you. Politely, usually in German, and once. The published consequences are more serious — removal without refund, and Erding charges €30 for deliberate soiling — but those exist for people who argue, not for a visitor who sat down on the wrong towel.

Is it the same in Austria and Switzerland?

The core is. The details are not: minimum ages differ, Austrian venues frequently offer separate women’s and men’s sauna areas, and the phone rules vary. We compared two of them on the German vs Austrian sauna rules page.

Two things to settle before you pick a date: the venue’s age limit, and whether that weekday is a women-only sauna day.
