Sauna etiquette in Finland: rules and what not to do

Finnish sauna etiquette is straightforward once you know the basics: be clean before you enter, stay quiet and respectful, and follow the lead of your host or the locals around you. The sauna is a place of genuine relaxation and social equality in Finnish culture, not a performance or a test of endurance. This article answers the most common questions visitors have before stepping inside.

Is nudity required in a Finnish sauna?

In traditional Finnish sauna culture, nudity is the norm rather than the exception. Finns use the sauna without swimwear because clothing is considered unhygienic in the heat and because the sauna is viewed as a natural, unpretentious space. That said, nudity is not a strict rule — it is a cultural default, and context always matters.

Public saunas, hotel saunas, and group experiences with mixed company often provide the option to wear a towel or swimwear, and no one will pressure you to do otherwise. The key principle is that you should never make others feel uncomfortable. If you are visiting a private sauna with Finnish hosts, following their lead is the right approach. Most Finns will not comment on your choice either way — they are focused on relaxing, not policing what you wear.

In single-gender settings, such as a traditional lakeside sauna shared with friends, going without a towel is the expected norm. In mixed or semi-public settings, wrapping yourself in a towel is perfectly acceptable and widely practiced.

What are the basic rules of Finnish sauna etiquette?

The basic rules of Finnish sauna etiquette are: shower before entering, sit on a towel, keep your voice calm, respect others’ space, and never rush. Finnish sauna customs are built around consideration for other bathers and a shared understanding that the sauna is a place to slow down, not socialise loudly.

Here are the core guidelines to follow:

• Shower first. Always rinse off before entering the sauna. This is both a hygiene standard and a sign of respect for others sharing the space.
• Sit on a cloth/towel. Place your cloth or towel on the bench before sitting. It keeps the benches clean and protects your skin from the hot wood.
• Keep noise low. Conversation is welcome, but loud voices, phones, and disruptive behaviour are not. The sauna is a space for calm.
• Ask before throwing water on the stones. If you are not alone, check with others before adding löyly. Not everyone tolerates the same level of steam.
• Move to a lower bench if the heat is intense. Heat rises, so the top bench is the hottest. There is no shame in sitting lower.
• Cool off between rounds. Step outside, jump in a lake, or stand in the fresh air between sauna sessions. This is part of the ritual, not optional recovery.
• Leave the sauna as you found it. Rinse the benches with water when you are done if it is a private sauna, and always take your towel with you.

Finnish sauna behavior is governed more by common sense and mutual respect than by a rigid rulebook. When in doubt, observe what the people around you are doing.

What should you never do in a Finnish sauna?

The things you should never do in a Finnish sauna include using your phone, speaking loudly, wearing outdoor shoes on the sauna floor, and pouring excessive water on the stones without asking. These behaviours break the atmosphere and show a lack of awareness of sauna customs in Finland.

A few specific things to avoid:

• Do not bring your phone in. The heat will damage it, and checking your phone signals that you are not present. Leave it outside.
• Do not pour large amounts of water on the stones repeatedly. Too much steam too quickly can make the sauna unbearable for others and can even damage the kiuas (sauna stove) over time.
• Do not wear shoes inside. The sauna floor is clean and often wet. Shoes track in dirt and are simply out of place.
• Do not stay in if you feel unwell. The sauna is not a competition. If you feel dizzy, lightheaded, or overheated, leave immediately and cool down. No one will think less of you.
• Do not shave or apply cosmetic products inside the sauna. This is unhygienic and inconsiderate to others sharing the space.
• Do not slam the door. Heat escapes quickly, and a slamming door is jarring in a quiet environment.

The overarching principle is simple: what not to do in a sauna is anything that prioritises your own comfort at the expense of others, or anything that treats the sauna as a casual social venue rather than a place of genuine rest.

How hot should a Finnish sauna be, and how long should you stay?

A traditional Finnish sauna is typically heated to between 70°C and 100°C (160°F to 212°F) at bench level, with 80°C to 90°C being the most common range for experienced bathers. First-time visitors often find 70°C to 75°C more comfortable. Most people stay in the sauna for 10 to 20 minutes per round before cooling off.

There is no single correct temperature or duration — Finnish sauna customs emphasise listening to your own body rather than pushing through discomfort. The goal is deep relaxation, not endurance. A typical sauna session involves two to four rounds, with cooling-off periods between each. Those cooling breaks are as important as the heat itself.

If you are new to sauna bathing, start on a lower bench where the temperature is gentler, and aim for shorter rounds of around 10 minutes. As your body adjusts over time, you can move higher and stay longer. Hydration matters too: drink water before and between rounds, and avoid entering the sauna already dehydrated.

What is löyly and how do you use it properly?

Löyly (pronounced roughly as “loy-loo”) is the steam that rises when water is poured over the hot sauna stones. It is central to Finnish sauna culture and dramatically affects the perceived heat and humidity inside the sauna. Using löyly properly means adding small amounts of water at a time, checking with others first, and using a ladle rather than pouring directly from a bucket.

The stones on a Finnish sauna stove (kiuas) store heat, and when water hits them, they release it as steam. This raises the humidity and creates a wave of intense warmth that feels very different from dry heat alone. A small ladleful of water is usually enough for one round of steam. Adding too much water too quickly can make the sauna overwhelming, especially for those sitting on upper benches.

Some hosts add a few drops of birch tar, pine resin, or tar soap to the water for scent, which is a traditional practice. If you are a guest, it is polite to ask before doing this yourself. The person closest to the kiuas often takes responsibility for adding löyly, but in a shared sauna, it is always a good idea to ask the group before each addition.

Experiencing löyly in different sauna settings is one of the highlights of a sauna-led trip in Finland. Our Ultimate Sauna Tour takes guests through multiple sauna types, from smoke saunas to lakeside cabins, each with their own distinct version of this ritual.

Should you drink alcohol in a Finnish sauna?

Drinking alcohol inside a Finnish sauna is not recommended and is widely considered unsafe. The combination of heat, dehydration, and alcohol raises your heart rate and impairs your body’s ability to regulate temperature, which significantly increases the risk of dizziness, fainting, or worse. Finnish sauna etiquette strongly favours water or soft drinks during a sauna session.

That said, there is a longstanding cultural tradition of enjoying a cold beer or cider after the sauna, not during it. This post-sauna moment, often shared outdoors by a lake or on a cabin terrace, is a cherished part of Finnish social life. The key distinction is timing: alcohol before or during the sauna is a genuine health risk, while a relaxed drink after you have cooled down fully is a different matter entirely.

If you are planning a sauna holiday in Finland, keeping well hydrated with water throughout your session will make the experience far more enjoyable. The contrast of heat, cold water, and fresh northern air is already deeply satisfying on its own. For those curious about exploring Finnish sauna traditions across different settings, our 7-Day Sauna Tour in Lapland is designed around exactly that kind of unhurried, culturally rich experience.
