Sauna Etiquette at the Gym: The Rules Nobody Tells You
Your gym probably has a sauna. It probably also has zero posted rules about how to use it. So you walk in, figure it out as you go, and hope you're not doing something wrong. Meanwhile, someone else is in there doing that thing that drives everyone crazy.
Gym saunas have their own set of unwritten rules. Here's what everyone should know but nobody tells you during your gym tour.

The Non-Negotiable Basics
Sit on a Towel
This is gym sauna rule number one. Always sit on a towel. Not the bench. Not a thin piece of paper towel. A full towel that covers the area where your body contacts the bench. You're sweating, and the person after you doesn't want to sit in your puddle. It's also more hygienic for you - gym sauna benches see dozens of people a day.
Shower Before Entering
You just worked out. You're sweaty and probably wearing deodorant. A quick rinse takes 60 seconds and dramatically improves the air quality for everyone sharing the space. Body odor in a 180F room is exponentially worse than body odor at room temperature. Be the person who rinses off. Don't be the person everyone is quietly wishing had rinsed off.
Wear Something
In most American gym saunas, nudity is not the norm. A swimsuit, shorts, or a towel wrap is expected. Check your gym's rules - some have them posted, others just have a general locker room dress code. When in doubt, cover up. Nude is fine in single-gender locker room saunas at some gyms, but observe what others are doing before you commit.

Phone Etiquette
This is the most violated rule in gym saunas. Leave your phone outside. Here's why:
- Nobody wants to listen to your music, videos, or phone conversation in a 6x8 foot room
- Camera phones in a space where people are in towels or swimsuits create obvious privacy concerns
- The heat damages your phone over time
- The sauna is one of the last phone-free zones. Let it stay that way.
If you need a timer, use a watch or the clock on the wall. If your gym's sauna doesn't have a clock, ask management to install one.
Volume Control
A gym sauna is a shared recovery space. Quiet conversation between two people is fine. But loud talking, FaceTime calls, business negotiations, or group conversations at full volume ruin the experience for everyone else.
Read the room. If someone is sitting quietly with their eyes closed, they're not looking for a chat. If the sauna is empty and a buddy joins you, a normal conversation is perfectly fine.
Temperature and Steam
Don't Crank the Thermostat
If others are in the sauna, don't adjust the temperature without asking. Some people prefer moderate heat, others like it blazing. A quick "Mind if I turn it up?" costs nothing and prevents resentment. If you're the only one in there, adjust to your preference, but know that someone walking in after you might find it uncomfortably hot.
Water on Stones
If your gym sauna has a rock heater, ask before pouring water. The steam burst is intense and some people don't want it - especially in a packed sauna where the heat is already borderline. A little warning goes a long way.
Space and Positioning
- Don't spread out if the sauna is crowded. Sit upright and give others room. Lying down across an entire bench when others need to sit is inconsiderate.
- Don't sit right next to someone when the sauna is empty. Give people their space. Choose the opposite bench or the far end.
- Keep personal items outside. Water bottles, bags, shoes - leave them in the locker room. The sauna is not a storage space.
Hygiene Issues
These should be obvious but apparently need stating based on what happens in gym saunas:
- Don't shave, trim nails, or groom in the sauna. This belongs in the locker room, not in a shared heat space.
- Don't wring your towel onto the bench or floor. Wring it over a drain or outside the sauna.
- Don't spit. Yes, this needs to be said.
- Wipe down the bench when you leave. If your gym provides cleaning supplies near the sauna, use them.
- Don't bring food. Water is fine. Everything else stays outside.
Exercise in the Sauna
Stretching, pushups, crunches, yoga poses - people do all kinds of exercises in the sauna. Unless you're the only one in there, don't. The space is too small, the floor is too hot, and the sweat flying around during your burpees is hitting someone else. If you want hot yoga, go to a hot yoga class. The sauna is for sitting and sweating.
Timing and Duration
- Be aware of peak times. Right after popular classes, early morning, and after-work hours are when the sauna is busiest. During these times, keep sessions reasonable (15-20 minutes) so others can use the space.
- Don't camp out. Spending 45 minutes in a gym sauna during busy hours is inconsiderate. Do your session, cool down, and free up the space.
- Close the door quickly. Every time the door opens, heat escapes. Enter and exit efficiently.
The Bottom Line
Gym sauna etiquette is really just basic shared-space courtesy: be clean, be quiet, be considerate of others, and leave the space how you'd want to find it. Sit on a towel, shower first, keep your phone outside, and don't exercise in there. Do these things and you'll never be "that person" in the sauna. Get these wrong, and trust me - everyone in there is silently judging you.
