Etiquette in Public Facilities and Spas

Why etiquette matters in shared heat

A public sauna is a shared environment where heat, humidity, and air are all communal. Your behavior directly affects the comfort and safety of every person in the room. Following the house rules is not just polite, it is the only way the space works well for everyone.

Facilities often have specific guidelines about how long to stay and what to do before and after your session. These rules are not random; they are based on hygiene and on how the body responds to heat. As one health resource advises, it is important to follow the guidelines of the sauna you are in so that your body does not overheat.

The social norms of a public sauna are usually learned by example. Watch what regular visitors do, and when in doubt, ask the attendant. A respectful question is always better than a quiet violation.

• Know the posted rules before you enter.
• Ask staff if anything is unclear.
• Follow the same routine every time: shower, sit, cool down, repeat.

Always shower before you enter

Showering before you enter the sauna is the single most important rule in any public facility. This shower before entering rule removes sweat, dirt, and any products like lotions or perfumes from your skin. This keeps the sauna clean for the next person and prevents strong smells from lingering on the benches.

This is not just a courtesy. In Finland, the home of the sauna, washing before entering is a central part of the ritual. It is expected that you arrive clean, and then use the sauna to sweat, after which you wash again. Many public saunas provide showers in the changing area exactly for this purpose.

Rinse thoroughly, including your hair if you use products. Then dry off before you step into the heat, because a wet body will sweat faster and may feel uncomfortable. Some facilities ask you to rinse again between rounds if you leave and return.

• Shower with soap and water before your session.
• Rinse off any chlorine or salt if you came from a pool or the sea.
• Take a quick rinse between sauna rounds if you leave the room.

The towel rule: sit on a barrier

In almost every public sauna, you are required to sit or lie on a towel. The reason is simple: sweat soaks into the wood, and no one wants to sit in someone else's sweat. A towel provides a barrier between your skin and the bench, and it is also more comfortable against the hot wood.

Bring a large cotton towel specifically for sitting, and keep it separate from the towel you use to dry off after your shower. The proper sauna towel size and fabric matters for comfort. Many people bring two towels for this reason. The sitting towel will get wet and covered in sweat, so it should be laundered after every use.

If you are using an infrared sauna or a portable sauna at a gym, the same rule applies. The bench material absorbs sweat, and a towel is the only thing protecting the next user. When you leave, take your wet towel with you and place it in the designated bin, not on the floor for someone to trip over.

• Use a separate towel for sitting.
• Sit on your towel even if the bench looks dry.
• Take your wet towel out when you leave.

Quiet voices and respectful silence

A sauna is a place to relax, and most people go there to be quiet. Loud conversations, shouting, and phone calls are out of place. Keep your voice low, and if you need to talk, wait for a pause or step outside.

This is especially important in small saunas where sound carries. A room that holds four or six people can feel much smaller when someone is talking loudly. The same courtesy extends to the changing room and the cool-down area.

It is acceptable to say hello when you enter and goodbye when you leave. Many regular visitors also appreciate a nod or a wave. But the general rule holds: the sauna is a calm space, and your voice should reflect that.

• Speak in a low voice or not at all.
• Turn off your phone or leave it outside.
• Keep conversations brief and step out for anything longer.

Respecting time and personal space

Public saunas are often busy, and your time in the heat should be considerate of others. A typical session lasts between 10 and 20 minutes, after which it is polite to take a break and let someone else have a spot. If the room is crowded, it is especially important to keep your session short.

Personal space matters. Sit or lie down so that you are not blocking the door, the heater, or the bench where someone else needs to sit. If the room is full, avoid spreading out your towel across two benches, and do not save seats for people who are not there yet.

When you leave, take your towel and any other items with you. Do not leave wet towels on the bench or the floor. If the facility has a rule about reserving benches, follow it.

• Keep sessions to 10 to 20 minutes when the room is busy.
• Do not take up more bench space than you need.
• Leave the room clean and dry for the next person.

How to handle water on the stones

In a traditional sauna, how to pour water on stones is a skill that creates steam and raises the humidity quickly. This is a wonderful part of the experience, but it can be surprising for others if done without warning. Always sprinkle a small amount, never pour a full ladle, and watch the reaction of the people in the room.

One source compares the effect to a shared experience: the burst of steam, called loyly in Finnish, is best appreciated by everyone together. If you are the only person in the sauna, you can add as much water as you like. If others are present, ask if they want more steam or go slowly.

Never add water to an infrared sauna heater. Infrared saunas use radiant heat and have no stones for this purpose. Adding water can damage the unit and create a safety hazard. The same caution applies to steam showers, where the steam is generated automatically by the system, not by pouring water.

• Sprinkle water in small amounts, one ladle at a time.
• Check with others before adding steam.
• Never pour water on an infrared heater.

After your session: cool down and clean up

When you finish your sauna, take a break to cool down. This is an important part of the process; it helps your body adjust and is a chance to drink water. After you have cooled down, take a shower or a bath to remove the sweat and salts left on your skin. It is also a good time to focus on hydration before and after your session.

A quick rinse after your session is recommended, and many facilities provide a shower for exactly this purpose. It also helps keep the changing room clean. Moisturizing your skin afterward is a good idea, as the heat can dry it out.

If you used a towel, place it in the laundry bin. Check that you have not left any personal items, and make sure the bench and floor are dry. This is the same courtesy you would want from the person before you.

• Cool down gradually before you shower.
• Shower off sweat and salts after your session.
• Take your towel and any trash with you.

Phones and other electronics stay outside

The heat, humidity, and moisture in a sauna are not good for phones and electronics in heat. More importantly, a phone has no place in a public sauna. It distracts the user and disturbs the peace for everyone else.

Leave your phone in the locker. If you must keep it with you, set it to silent and do not use it in the sauna room. Taking a phone inside also invites the temptation to take photos, which is a serious privacy violation in a public changing area.

The same goes for headphones. Music or a podcast might help you relax at home, but in a shared space, it isolates you from the social cues of the room. Enjoy the quiet, or talk with the people around you if they are open to it.

• Leave your phone in the locker.
• Do not take photos or videos in the sauna or changing rooms.
• Avoid headphones and other devices in the sauna room.

Hygiene and public health basics

The most important hygiene rule is to shower before you sit, and to sit on a towel. These two actions prevent the spread of skin infections and stop the benches from absorbing sweat. They are the foundation of public sauna etiquette.

If you have a contagious skin condition, an open wound, or an active infection, you should avoid the public sauna until it clears. The same guidance applies if you are feeling unwell. A sauna is not a cure for a cold, and your body may not handle the heat well when you are sick.

If you are pregnant or have a health condition, check with a doctor before using a sauna. The heat can be safe for many people, but it is not right for everyone. Your doctor is the only person who can advise you on your specific situation.

• Shower before you enter and sit on a towel.
• Stay home if you have a contagious skin condition.
• Check with a doctor if you have any health concerns.
