Overview
What it is
Yrjönkatu Swimming Hall is Helsinki’s old-school indoor bathhouse, known for its 1920s interiors, a long pool, and a sauna routine that feels more like a city spa than a sports facility. It is not a natural hot spring. The draw is the atmosphere and the way people actually use it: slow laps, sauna rounds, cooling off, then a proper rest.
What makes it different
You can swim in a swimsuit or swim naked, depending on your comfort level and the day’s setup, and the hall runs women’s and men’s swimming days. That keeps the vibe distinct from modern mixed pools. There is also an “upstairs” option with private resting cabins, which turns a quick swim into a longer, quieter reset.
What to expect
Expect a calm, rules-light culture where people keep their voices down and stick to the sauna rhythm. This is the kind of place where you leave your phone in the locker and you feel better for it.
Location & Access
Where it is
The hall is in central Helsinki in the Kamppi area, at Yrjönkatu 21 b. It sits next to major shopping and transit corridors, so you do not need a car and you do not need to plan for weather beyond the walk from the stop.
Getting there
Public transport is the easy move. Many trams and buses stop nearby, and walking from Helsinki Central Station is realistic if you are staying in the core. If you do drive, treat parking as garage-based city parking rather than “pull up outside”, there is a garage in the adjacent Forum complex, but spaces and pricing are always subject to change.
What to bring
Bring a swimsuit if you want the option to wear one, plus a towel for drying and something simple to wear between areas. If you are doing the cabin level, a spare towel and basic toiletries make the rest break nicer. Flip-flops help on wet tiles. Keep cashless payment and ID basics handy, and leave valuables minimal. This is a city facility, not a resort, so bring what you actually use and keep it compact.
Suitability & Accessibility
Who it suits
This is best for adults and confident first-timers who want a classic Finnish bathhouse feel without leaving the city centre. If you like long, quiet sauna rounds and a steady pace, it fits. If you want loud social energy, slides, or a resort circuit, it will feel too restrained.
Families
Even if children are allowed, most families will find the tone adult-leaning. The nude-or-swimsuit tradition and gendered swimming days can be awkward to navigate with kids, and the etiquette expects people to move calmly and keep noise down. If you are travelling with children, a family-focused pool complex is usually a smoother plan.
Mobility and accessibility
I am not marking this as wheelchair accessible. Older buildings often have thresholds, tight corners, and changing areas that can be limiting. If you need step-free routes, lifts, or adapted changing, check the venue’s current accessibility details before you commit, especially if you are planning the upstairs cabins.
Expectations vs reality
Think “city bathhouse with real sauna culture”, not “thermal spring”. The water is pool water, the value is the place and the routine.
Safety & Etiquette
Heat and hydration
Sauna heat stacks up. Keep your first round short, cool down fully, and drink water between rounds. If you feel lightheaded, sit, breathe, and take a longer break before you go back in. This is especially true if you are combining swimming laps with sauna time, exertion plus heat can sneak up on you.
Wet floors and slips
Tiles, showers, and pool edges get slick. Move slowly, especially when you stand up after a sauna round. Flip-flops reduce the risk and also keep things more comfortable in shared areas.
Nudity and privacy etiquette
Because nude swimming is part of the tradition, privacy matters. Avoid staring, keep conversation low, and do not bring cameras into spaces where people are undressed. If you are unsure what is normal on a given day, follow the lead of regulars and staff guidance, and choose the simplest option for you.
Sauna basics
Sit on a towel. Keep fragrances light, strong scents linger in hot rooms. Give people space at the door and on benches, and avoid turning sauna time into a performance. Quiet, steady rounds are the whole point.
When to skip it
If you are ill, feverish, or recovering from a stomach bug, save it for another day. Shared warm environments are not the place to “push through”.
FAQs
Is there an entry fee?
Yes. Entry is paid, and there are typically different ticket options (for example, basic access versus added facilities such as resting cabins). Check the official City of Helsinki page for current tickets.
Can you wear a swimsuit?
Yes. The venue notes that you can wear a swimsuit or swim naked. The hall also runs women’s and men’s swimming days, so check which day matches your plan.
Do you need to book ahead?
For standard visits, many people simply arrive, but popular times can be busy. If you are travelling on a tight schedule or you specifically want the cabin option, check current guidance before you go.
What should you bring?
A towel, flip-flops, and toiletries for showering are the basics. Bring a swimsuit if you want that option. A small bag makes moving between lockers, pool, and sauna simpler.
Is it wheelchair accessible?
Do not assume. Accessibility can vary in older buildings and between floors. Confirm step-free access, lift availability, and changing-room setup with the venue before you plan your visit.
