In a sauna, keep it simple and natural: many people wear little or nothing beyond a towel to sit on and wrap in, while others wear swimwear, depending on the setting and their comfort and the norms of the sauna. Avoid heavy synthetic clothing that traps heat and sweat, and remove metal jewellery and watches, which can get uncomfortably hot against the skin. Bring a towel to sit on (good hygiene and etiquette), and for an outdoor sauna have a robe and warm footwear for the cold approach and cool-down. Above all, wear what's comfortable and appropriate to the setting — a private home sauna and a public one may have different norms.
“What do I wear?” is one of the most common first-timer questions — and the answer is refreshingly simple: keep it natural, keep it comfortable, and respect the setting. There’s no universal uniform, but there are a few sensible principles about towels, materials and jewellery that make any sauna more comfortable. This guide covers what to wear, and what to bring, for a sauna.
Keep it simple and natural
In a sauna, less and lighter is more comfortable. Depending on the setting and your comfort:
- Many people wear little or nothing beyond a towel to sit on and wrap in.
- Others wear swimwear — common in public or mixed settings, and handy if you’ll also use a cold plunge or pool.
There’s no single rule — it varies by setting, comfort and the sauna’s norms.
Always: a towel to sit on
Whatever else, bring a towel to sit on. It’s:
Bring one to sit on and one to dry off.
Avoid: synthetics and metal
What to bring to an outdoor sauna
Beyond what you wear inside, an outdoor sauna calls for a few extras for the cold approach and cool-down:
| Bring | For |
|---|---|
| Towel (to sit on) | Hygiene & etiquette |
| Towel (to dry off) | After cool-downs |
| Robe | The cold approach & cool-down |
| Warm, non-slip footwear | Icy footing in winter |
| Water | Staying hydrated |
In winter, the robe and footwear make a real difference to comfort and safety on icy footing — see winter comfort tips.
Respect the setting’s norms
Conventions vary by setting and culture — private home saunas, public saunas and traditional saunas may differ around clothing, from towels to swimwear. The key is to respect the norms of the particular sauna and wear what’s comfortable and appropriate there:
- Private home sauna — more freedom.
- Public sauna — follow its norms.
When in doubt, observe what others do or ask — a towel or swimwear is usually a safe choice.
Common mistakes
- Heavy synthetics that trap heat and sweat.
- Metal jewellery that heats up uncomfortably.
- No towel to sit on — poor hygiene and etiquette.
- Forgetting a robe and footwear for a cold outdoor approach.
- Ignoring the setting’s clothing norms.
Next steps
Keep it simple and natural: a towel to sit on (always), swimwear or minimal as suits you and the setting, no heavy synthetics or metal, and — for an outdoor sauna — a robe, warm footwear and water for the cold transitions. Respect the setting’s norms, and you’ll be comfortable and considerate — see how to use a sauna for the rest.
Frequently asked questions
What should you wear in a sauna?
Keep it simple and natural: many people wear little or nothing beyond a towel to sit on and wrap in, while others wear swimwear, depending on the setting, their comfort, and the sauna's norms. Avoid heavy synthetic clothing that traps heat and sweat, and remove metal jewellery and watches, which get hot against the skin. Bring a towel to sit on for hygiene and etiquette. Wear what's comfortable and appropriate to the particular sauna — a private home sauna and a public one may differ. Comfort and the setting's norms are the guide.
Do you wear clothes in a sauna?
It varies by setting and personal comfort — many people wear little or nothing beyond a towel, while others wear swimwear, and norms differ between private home saunas, public saunas and different cultures. There's no single rule. What matters is being comfortable and respecting the norms of the particular sauna you're in. If you're unsure, a towel to sit on and wrap in, or swimwear, is a safe, common choice. Observe or ask about the setting's conventions, and wear what suits you within them.
Should you wear a swimsuit in a sauna?
You can — swimwear is a common and comfortable choice in many settings, especially public or mixed ones, and it works well if you'll also use a cold plunge or pool. Others prefer just a towel. If you wear swimwear, avoid heavy synthetic materials that trap heat, and a lighter swimsuit is more comfortable in the heat. Whether swimwear or a towel suits depends on the setting and your preference. In a private home sauna you have more freedom; in a public one, follow its norms.
Why should you avoid synthetic clothing and jewellery in a sauna?
Heavy synthetic clothing traps heat and sweat against the skin, which is uncomfortable in a sauna, and natural materials or minimal clothing are more comfortable. Metal jewellery and watches can heat up against the skin in the high temperature and become uncomfortably hot, so it's best to remove them before a session. So avoid heavy synthetics and take off metal jewellery for comfort. Keeping it simple and natural — a towel, or light, natural materials, and no metal — makes for a more comfortable, safer sauna experience.
What should I bring to an outdoor sauna?
A towel to sit on (essential for hygiene and etiquette) and one to dry off, plus, for the cold approach and cool-down, a robe and warm, non-slip footwear so the transitions between the hot sauna and cold outdoors are comfortable and safe. Water to stay hydrated is wise too. In winter especially, the robe and footwear make a real difference to comfort and safety on icy footing. So beyond what you wear inside, bring towels, a robe, warm footwear and water. See our winter comfort tips for more.
Are there rules about what to wear in a sauna?
There's no universal rule, but there are norms that vary by setting and culture — private home saunas, public saunas and traditional saunas may have different conventions around clothing, from towels to swimwear to nothing. The key is to respect the norms of the particular sauna and wear what's comfortable and appropriate there. When in doubt, observe what others do or ask, and a towel or swimwear is usually a safe choice. Comfort, hygiene (a towel to sit on) and the setting's conventions are what guide sauna dress.
