5.5 Million People, 3.2 Million Saunas: Your Guide to Surviving a Finnish Sauna

5.5 Million People, 3.2 Million Saunas: Your Guide to Surviving a Finnish Sauna

I visited Löyly, a public sauna in Helsinki, for the first time. As I was about to put on my swimsuit in the locker room, the person next to me walked straight in with nothing but a towel. "To wear or not to wear?" No one tells you. To Finns, the sauna is such an instinctive part of daily life that it doesn't even occur to them that an explanation might be needed.

The Sauna is Finland’s Living Room

In Finland, there are approximately 3.2 million saunas for a population of 5.5 million. There’s one in almost every home, as well as in hotels, offices, and even the Parliament House. For Finns, a sauna isn't just a place to wash; it’s a sanctuary for the soul, where people unwind from the day's stress and share honest conversations with family and friends.

Business meetings are held in saunas, and major life decisions are made there. Being invited to a Finnish sauna is more than just a tourist activity—it’s an invitation into the most private space of their culture.

However, this space comes with its own set of rules, and those rules change depending on the type of sauna you're visiting.

Naked or Swimsuit? A Dress Code Guide by Sauna Type

The most confusing part of a Finnish sauna is deciding what to wear. The answer is simple: it depends on the type of sauna.

In private saunas (Kotisauna) at homes or summer cottages, being naked is the standard. You simply sit on a towel placed on the bench. If you're invited to a Finnish friend's home, follow the host's lead. While insisting on a swimsuit might make things a bit awkward, you always have the right to decline—no one will ever force you.

In Helsinki’s public saunas (Löyly, Allas, etc.), facilities are usually divided by gender. Inside the sauna, being naked or wrapped in a towel is common, but swimsuits are mandatory in outdoor pool areas. Look for the M (Miehet/Men) and N (Naiset/Women) signs at the entrance. Some places also alternate hours for men and women.

Hotel saunas often allow swimsuits or towels to accommodate international tourists. If it’s your first time experiencing a Finnish sauna, starting at a hotel is a great way to ease in.

Smoke saunas (Savusauna) are the most traditional form. These are heated by smoke without a chimney, then ventilated before entry. Nudity is the rule here, and the experience often includes a ritual of gently tapping your skin with a bundle of birch twigs called a vihta.

Regardless of the type, one rule remains constant—there is a strict etiquette to follow before you step inside.

Ask Before You Bring the Steam

The core of Finnish sauna etiquette is respect for others, much like the principles of a Japanese onsen.

First, always shower before entering the sauna. Makeup, perfume, and lotions must be washed off. This is a matter of hygiene, and chemical scents can become unpleasant for others when they evaporate in high temperatures.

Second, don’t sit directly on the bench; use a towel. It’s more hygienic than skin-to-wood contact and protects you from the heat of the bench.

Third, follow Löyly (steam) etiquette, the highlight of any Finnish sauna. This involves throwing water over the stove to create steam, but you shouldn't do it whenever you feel like it. Always ask the others first: "May I throw some löyly? (Saako heittää löylyä?)" A sudden spike in temperature can be uncomfortable for some.

Fourth, keep conversations quiet. The sauna is a meditative space. Loud voices, business calls, and, of course, photography are strictly off-limits.

Finally, jumping into a cold lake or the sea after stepping out of the heat is a classic Finnish tradition. While not mandatory, Finns consider this the heart of the sauna experience. If you’re not feeling brave, a cold shower is a perfectly refreshing substitute.

What to Pack in Your Sauna Bag

You don’t need expensive gear for a Finnish sauna, but a few essentials will make the experience much more comfortable.

A swimsuit (for public pool areas), two large towels (one for the bench and one for drying off), and slippers (for the locker room and hallways) are the basics. Complete your kit with a hydrating drink, moisturizer for after the heat, and a fresh change of underwear. If you have long hair, a sauna beanie can help protect it from the heat.

This list actually overlaps quite a bit with what you'd pack for a trip to a Japanese hot spring. Despite the different countries, the principle of a shared bathing culture remains the same. The rules of respect are universal.

You are briefly participating in a culture that 5.5 million people have built daily across 3.2 million saunas. Laying down a towel, sitting in silence, and feeling the steam rise over your skin—that is the essence of the Finnish sauna.
