Sauna Attire Explained: What to Wear (and What to Avoid)

Why What You Wear Matters: Comfort, Hygiene, and Safety

Your sauna outfit isn’t just about following the crowd. It’s about staying safe, clean, and comfy while you soak up that heat.
Ever tried sitting in a sauna wearing tight gym leggings? Not fun. You end up feeling like a baked potato.

Choosing the right attire keeps your body cool, prevents skin irritation, and makes sure you don’t gross out your fellow sauna-goers.
Plus, it helps you relax, which is the whole point of sweating it out, right?

Cultural Norms: Nudity vs. Clothing in Saunas

The Traditional Finnish Approach

In Finland, saunas are practically a way of life.
And yes, you’ll often find everyone going fully nude, with just a towel to sit on.

It’s not about showing off, though. For Finns, the sauna is a clean, peaceful place where your skin breathes freely and no one cares what you look like.
It’s more about connection and health than fashion or modesty.

Common Practices in the UK and Public Facilities

Step into a UK spa or gym, and it’s a different story.
Most people opt for modesty—think swimwear, towels, or loose T-shirts.

Some gyms even have rules posted on the wall (awkward if you miss them).
Best tip? Check the signage, or discreetly ask the staff if you’re unsure. When in doubt, go minimal but covered.

Acceptable Sauna Wear Options

Nude (Where Appropriate) + Towel Etiquette (Sitting On)

In places where nudity is the norm—like traditional spas or private saunas—it’s perfectly fine to go as nature intended.
But never skip the towel when sitting down. It’s a basic sauna rule to keep benches clean and respect others’ comfort.

Think of it as your invisible seat cover. No one wants to sit where someone else’s sweat was five minutes ago.

Towel Wrap: Modesty and Absorption

For those who prefer a middle ground, a simple towel wrap is your best friend.
It covers what needs covering, soaks up sweat, and keeps things breathable.

Pro tip? Go for lightweight cotton towels that dry quickly—nobody wants to haul a soggy blanket around.

Swimwear: Check Rules and Choose Materials Wisely

Swimwear works well in gyms, hotels, or family saunas.
But choose wisely—thick, clingy swimsuits can feel like a wetsuit in the heat.

Stick to breathable, non-restrictive styles, and always check the venue rules first.
Some places frown upon swimwear, while others require it.

Loose Cotton Clothing (T-shirts, Shorts)

If you want to stay clothed but comfy, loose cotton T-shirts and shorts are safe bets.
They won’t trap heat, stick to your skin, or make you feel claustrophobic.

Ideal for beginners who aren’t quite ready for the full Finnish experience.

What Absolutely Not to Wear in a Sauna

Street Clothes, Shoes, and Dirty Attire

Leave the jeans, hoodies, and muddy trainers at the door.
Street clothes carry oils, dirt, and smells—things that do not mix well with steamy rooms.

And shoes? Always a firm no.

Tight Clothing and Synthetic Materials (Nylon, Polyester)

Avoid tight clothes like gym leggings or compression tops.
They trap sweat, overheat your body, and can cause skin irritation.

Synthetic fabrics like polyester or nylon also get sticky and uncomfortable.
Not exactly the zen moment you’re after.

Anything with Metal (Jewellery, Zippers, Fasteners)

Metal heats up fast in a sauna—and yes, it can burn.
Take off jewellery, watches, or anything with zippers or hooks.

Better safe (and cool) than sorry.

PVC Swimsuits or Items

PVC or plastic-lined swimsuits?
Hard pass. They can melt, release nasty smells, and feel horrible against your skin.

Stick to natural fibres or sauna-specific garments.

Navigating Different Sauna Settings (Public vs. Private)

In private saunas, like your home, a rental cabin, or a friend’s place—you’ve got flexibility.
Some people love going au naturel; others feel better in a towel or T-shirt.

But in public saunas, gyms, hotels, or wellness centers, play it safe by following the posted rules or asking staff.
It avoids those cringy moments of being the odd one out.

Conclusion: Dressing for Comfort, Safety, and Respect

Sauna dress codes don’t need to be a puzzle.
It’s all about matching the vibe, respecting the space, and making sure you feel good in your own skin.

Whether you’re enjoying a naked lakeside sauna in Finland or a towel-wrapped session at your local UK gym, the golden rule is comfort, safety, and respect.
And remember—when in doubt, bring a towel. It never lets you down.
