Sauna Etiquette: The Unwritten Rules Everyone Should Know
Nobody hands you a rulebook when you walk into a sauna. But there are unwritten rules - some practical, some cultural - that separate a good sauna experience from an uncomfortable one.
Whether you're using a gym sauna, visiting a spa, or hosting friends in your home sauna, these are the etiquette basics that matter.

Shower First - Always
This is rule number one in every sauna culture worldwide. Take a quick shower before you enter the sauna. You don't need soap every time - a rinse is fine. The point is to wash off sweat, deodorant, lotions, and whatever else is on your skin.
Why it matters: In a small, hot room, body odor and chemical fragrances get amplified. Perfume that's barely noticeable at room temperature becomes overwhelming at 180°F. A quick rinse takes two minutes and makes the space pleasant for everyone.

The Towel Rules
Always sit on a towel. This is non-negotiable, and here's why: sweat on the bench is unsanitary, and direct skin contact with hot wood can actually burn. Your towel is your barrier.
Standard practice:
- Bring at least one large towel to sit and lie on. It should cover the full area your body touches - bench seat and backrest.
- Keep a second towel for wiping sweat during the session. Small hand towels work for this.
- In many European saunas, your towel is your only clothing. In American gym saunas, swimsuits or shorts are standard. Know the venue's norms before you strip down.
Clothing: Know the Setting
Clothing norms vary dramatically depending on where you're saunaing:
- Finnish and German public saunas - Nudity is the norm. Wearing a swimsuit is considered odd and sometimes discouraged because synthetic fabrics can release chemicals in the heat and prevent proper sweating.
- American gym saunas - Swimsuit, shorts, or a towel wrap is standard. Nudity is generally not acceptable in co-ed settings.
- Spa saunas - Check the spa's rules. Some have nude-only hours, some require swimwear, some have gender-separated nude sessions.
- Home saunas - Your sauna, your rules. Most people go nude at home since it's the most comfortable and practical option.
When in doubt, bring a towel and swimsuit and observe what others are doing. Never make someone else uncomfortable with your clothing choices (or lack thereof).
Keep the Volume Down
A sauna is a quiet space. This doesn't mean total silence - light conversation is fine. But loud talking, speakerphone calls, or group conversations at full volume ruin the experience for everyone else.
General guidelines:
- Speak at a low, conversational volume
- Don't shout across the sauna to someone on a different bench
- If someone else is clearly meditating or resting with eyes closed, keep it down
- In Finland, silence is the default. Talking is fine with people you know, but strangers typically nod and sit quietly
Phones Don't Belong in the Sauna
Leave your phone in the locker. This isn't just an etiquette issue - the heat and humidity will damage your phone over time. But more importantly, nobody wants to be in a sauna with someone scrolling through social media, taking photos, or - worst of all - making calls.
If you need a timer, use the sauna's built-in clock or a dedicated timer. Your sauna session is 15-20 minutes of being disconnected. That's a feature, not a problem.
Temperature Courtesy
If you're sharing a sauna with others, temperature adjustments require consideration.
Thermostat Adjustments
Don't crank the thermostat up or down without checking with others in the room. If you want it hotter and someone else is there first, ask before touching the controls. "Mind if I bump this up a few degrees?" takes three seconds and prevents conflict.
Adding Water to Stones (Loyly)
In a traditional sauna with a heater and stones, throwing water creates a sudden burst of intense steam. This is a core part of Finnish sauna culture, but it dramatically changes the experience for everyone in the room.
Etiquette for loyly:
- Ask before throwing water if others are present: "Is a little loyly okay?"
- Start with a small amount - half a ladle, not a full bucket
- Give people time to react before adding more
- If someone says "no thanks," respect that
Opening the Door
Every time the door opens, heat escapes. In a busy sauna, constant door opening can make it hard to maintain temperature. Enter and exit quickly. Don't prop the door open. If you're going in and out for multiple rounds, be efficient.
Personal Hygiene and Consideration
- Don't shave or groom in a public sauna. This should be obvious but apparently isn't at some gyms.
- Wring out your towel over the drain, not on the bench
- Don't bring food into the sauna. Water is fine. Some saunas allow beer (Finnish tradition), but check the norms.
- Control hair dripping - Tie long hair up or wear a sauna hat so wet hair isn't dripping on the bench or other people
- Don't exercise - Pushups, stretches, or other exercises in a shared sauna are inappropriate. The space is too small and too hot for it.
Finnish Sauna Traditions
Finnish sauna culture has traditions worth knowing, especially if you're invited to a Finnish sauna or want to bring some authenticity to your home setup:
- Vihta/Vasta - Bundles of fresh birch branches used to gently swat the skin. This stimulates circulation and releases a pleasant, woodsy aroma. It's a centuries-old tradition, not punishment.
- Rounds - Finns typically do 2-4 rounds: sauna, cool down (cold water, swimming, or just sitting outside), repeat. The cool-down is as important as the heat.
- Post-sauna - In Finland, the sauna is often followed by food and drinks. It's a social experience, not just a sweat session.
- Respect the space - Finns consider the sauna a place of peace. The old saying goes: behave in the sauna as you would in church.
Home Sauna Etiquette
When you have guests using your outdoor sauna or indoor setup:
- Provide towels - Not everyone brings their own. Have extras ready.
- Explain the basics - Not everyone has sauna experience. A quick "here's how the temperature works, sit on a towel, exit if you feel lightheaded" covers it.
- Set expectations - Let guests know the clothing norms for your sauna before they're standing there unsure.
- Have water available - Keep a water station near the sauna so people stay hydrated.
- Show them the loyly - If you have stones, demonstrate the water-on-stones ritual. Many people have never experienced it and love it once they know what to do.
The Bottom Line
Sauna etiquette comes down to cleanliness, courtesy, and awareness of others. Shower before you go in, sit on a towel, keep your voice down, leave your phone outside, and ask before changing the temperature. Follow these basics and you'll be a welcome presence in any sauna, anywhere in the world.
