What to Bring to a Sauna: A Traveller's Packing Checklist

The core kit and why you need two towels

Sauna in the Lanes in Brighton spells out the two-towel logic neatly: you sit on one for hygiene and comfort, and you use the second to dry off after your rounds. The venue also rents towels for £2 each to guests who forget theirs, so a forgotten towel is an inconvenience rather than a ruined session.

A reusable bottle matters as much as the towels. That same Brighton sauna provides filtered water and asks guests to skip single-use plastics, so arriving with an empty bottle you can refill is the practical choice. Pack the bottle in your bag rather than carrying it into the hot room, and drink between rounds instead of during them.

If you want the per-round rhythm of a traditional session — how long people usually stay in, when they step out, how often they repeat — the Finnish sauna is the reference point most European venues work from. Build your kit around that cycle of heat, cool and rest rather than around a single long sit.

Swimwear or nude: reading the dress code before you pack

Some venues make the rule explicit. Sauna in the Lanes requires swimwear and rules out daywear or underwear inside the cabin, which means a proper swimsuit belongs in your bag and your gym kit does not. When a venue says swimwear is mandatory, that is not a suggestion about modesty: it is the house rule that keeps the benches clean.

Elsewhere in Europe, especially in Finland, Germany and the Baltic states, public saunas often expect bathers to go without textiles, sitting on a towel instead. Because the two conventions sit side by side across the continent, the honest packing move is to read the specific venue's guidance first and pack a swimsuit you would actually be comfortable sweating in.

If you are unsure which convention applies where you are heading, our guide to what to wear in a sauna walks through the towel, swimsuit and nude options room by room. It is worth five minutes of reading before you decide what goes in the bag.

What to leave at home

Leave the daywear, the underwear and the synthetic workout clothes at home. Tight polyester holds heat and moisture against the skin instead of letting it pass, and metal fastenings on swimwear can become uncomfortably hot on a bench. Cotton, linen and simple swim fabrics are the practical choices.

Jewellery, strong perfume and a full face of makeup all belong outside the hot room. Rings and necklaces heat up against the skin, scent intensifies in a small enclosed space shared with strangers, and makeup is better applied after your last round than before your first. A hair tie is the one small accessory worth keeping in the bag.

Phones are the other obvious omission. Sauna in the Lanes bans phones inside the cabin outright, and the same rule appears posted in most public saunas for the plain reason that nobody wants a camera in a room where people are undressed or unwinding.

Footwear and changing rooms

Flip-flops or sandals are for the walk between the sauna, the shower and the courtyard or plunge area, not for the bench itself. Many venues, including Sauna in the Lanes, ask guests to leave outdoor shoes on racks at the entrance and use a gender-neutral changing room above the cabin.

Lockers are common but not always free. Sauna in the Lanes runs security lockers that require a £1 coin as a deposit, so a small coin in your bag saves you hunting for one at the desk. Where a venue supplies no lockers at all, a travel padlock on your own bag is a lightweight precaution.

Arrive five to ten minutes before your slot so that changing, stowing your bag and finding the showers do not eat into your session. That buffer is also when you read the posted rules and work out which door leads to the cold water.

Water, food and one plain safety line

Bring water and drink it between rounds rather than inside the hot room. Skip alcohol before bathing, stay hydrated, leave the sauna if you feel unwell, and ask a doctor first if you have a heart condition or are pregnant.

Eating is best kept outside the sauna itself and between sessions, and some venues have a courtyard or lounge for exactly that. A refillable bottle plus a light snack for afterwards covers most visits; a full meal is a post-sauna pleasure, not a pre-sauna one.

Optional extras that earn their space

A sauna hat or headband keeps hair out of your face and takes the edge off the heat on your ears during longer rounds. A lightweight robe or cotton cover-up is useful for the walk to the cold water and for sitting out between rounds, particularly when the courtyard is shared with other bathers.

A small toiletry kit — soap, shampoo in a travel tube, a waterproof pouch — covers the shower before and after. Travellers who sauna frequently also pack a dry brush, a spare change of underwear and a tote for the wet kit on the way home.

A charged phone is handy for navigation and booking confirmation, even though it stays in the locker. Some venues run monthly passes or wristbands for regulars, which are worth asking about if you plan more than a couple of visits in one city.

How a session actually works

Most public saunas run on rounds rather than one long sit. In the Finnish custom, bathers typically stay in for five to fifteen minutes, step out to cool off and drink, then repeat a few times; the exact rhythm is a matter of custom, not a rule you will be timed on.

Shower before you enter, sit on your towel, and keep conversation quiet enough that others can relax. Where a venue is mixed rather than single-sex, swimwear rules usually tighten, so check the venue's own listing before you assume the German or Finnish convention applies.

If it is your first visit, book or check the session structure in advance where the venue takes bookings, and simply walk in where it does not. Removable benches, towel hooks and a clock outside the cabin are the details that tell you how the room is meant to be used.

Aufguss, saunagus and Löyly manners

Where an attendant pours water on the stones and circulates the steam with a towel, that is the Aufguss or saunagus ceremony, and the room's etiquette is different from a quiet sit. Sit where you can see the stones, keep still, and leave quietly if the heat becomes too much rather than pushing through it.

Löyly, the splash of water on hot stones, is a shared experience: you pour only when it is your turn or when the group invites it. Talking through a pour is the one clear breach of manners, and the same quiet applies when a ceremony is in progress.

Cooling off between rounds

The cold option is part of the kit question, because it shapes what you carry and wear. A plunge pool, an outdoor shower, a sea pool or a lake all mean a short walk outdoors, so sandals and a robe earn their place in the bag; a venue with an indoor plunge needs neither.

Expect the walk to be cold, especially in winter, and keep your towel within reach of the door so you are not hunting for it wet and shivering. Wrap up before you step outside and dress properly between rounds rather than lingering in a swimsuit in a cold courtyard.

Photos, phones and quiet

Assume no photography and no phone in the hot room unless a venue's signage says otherwise. The posted rules at public saunas are consistent on this point, and they exist to protect the people sitting next to you as much as to protect you.

Quiet conversation is usually fine, but raised voices and phone speakers are not. If you are visiting with friends, agree before you go in that you will keep talk low and leave the cabin together rather than in a noisy relay.

First-timer mistakes worth avoiding

The classic errors are overpacking, bringing one towel instead of two, forgetting water and staying in too long on the first round. Start short, cool off properly and add time on later rounds as you get a feel for the room.

The other mistake is ignoring the venue's dress code because a different country does it differently. Read the house rules for the specific sauna you have booked, not the general habit of the country you are in, and pack accordingly.

Day trip versus a single session

For a single session, the core kit plus a coin for the locker is enough: two towels, water, flip-flops and your swimwear if the venue requires it. A day trip adds a change of clothes, a bag for wet towels and something to eat between sessions if the venue has a courtyard or lounge.

A day that includes several saunas needs a dry bag for the wet kit and a second towel set. If you are heading to Helsinki specifically, the Finnish sauna guide covers the public venues and the Allas Sea Pool waterfront option in more depth.

Pack Once, Then Relax

If you remember only one thing, remember the two towels: one to sit on, one to dry off, and neither left at home. Add a refillable bottle, sandals and a coin for the locker, and you are equipped for almost any public sauna in Europe.

Everything else follows the venue's own rules on swimwear, phones and shoes, so read the house guidance before you pack and leave the synthetic gym kit behind.
