Fjordtokt Båt & Badstu: Complete Guide to Oslo's West-Side Sauna Boat

Fjordtokt Båt & Badstu sits at the quieter, western end of Oslo’s sauna scene — a short walk from Lysaker station rather than the crowded central waterfront at Aker Brygge or Langkaia. The name tells you exactly what it offers: båt (boat) and badstu (sauna), run as two connected but distinct experiences from the same small pier at Sollerud.

If you’ve read about Oslo’s sauna boats and pictured a wood cabin chugging across the fjord with steam pouring out, it’s worth knowing upfront that Fjordtokt isn’t quite that — and understanding the difference will save you from booking the wrong thing.

What Fjordtokt Actually Offers

At the tip of the pier outside Sollerud Båtbyggeri, Fjordtokt operates three wood-fired saunas: two floating (Neptun and Caldarium) and one on land (Afrodite). Each has direct access to the fjord for a cold dip, with views over the calm waters of Lysakerfjorden rather than the busier harbour traffic further into town. This makes it the only floating sauna on Oslo’s west side, and a genuinely different setting from the postcard shots of central Oslo’s waterfront saunas.

Separately, Fjordtokt operates Poseidon, a 33-foot (10-metre) wooden sailing vessel with a Bermuda rig — a main mast and a mizzen mast — available to charter for tours on the inner Oslofjord. Poseidon can carry groups of up to twelve people. Departures are typically from the Sollerud dock, with some tours also available from Aker Brygge in central Oslo.

The two products can be combined: charter the boat for a sail around the inner fjord, then finish at the dock with a private sauna session and a swim. That combination — a slower, more traditional sailing experience paired with a wood-fired sauna at a quiet mooring — is the actual character of a “Fjordtokt trip,” rather than a single vessel that does both at once.

How Fjordtokt Differs From KOK’s Sauna Cruise

It’s an easy mix-up, since both are described as “sauna cruises” on the Oslofjord, so it’s worth being precise. KOK, based at Aker Brygge and Langkaia in central Oslo, runs KOKCRUISE: a private sauna that is itself the moving vessel. It’s a wood-fired, birch-burning sauna boat fitted with a quiet electric motor, holding up to ten people, that motors out from Aker Brygge into the inner fjord for around two hours, anchoring in a bay so guests can jump straight from the sauna into the water. The heat and the journey happen in the same box.

Fjordtokt’s setup is structurally different. The saunas at Sollerud don’t move — they’re moored at the pier, and you experience them the way you would any floating sauna: sit, sweat, dip, repeat, with the fjord as a fixed backdrop rather than a passing view. If you want the boat element, that’s a separate booking on Poseidon, a proper sailboat under sail or engine, without a sauna on board.

Neither approach is “better” — they’re just different products solving the same basic craving (heat plus fjord). KOK suits people who specifically want the novelty of sweating inside something that’s driving across the water. Fjordtokt suits people who want a classic floating-sauna session in a quieter part of the city, with the option to add a genuine sailing trip on the side.

Booking Options and Group Sizes

Fjordtokt’s saunas can be booked two ways:

• Private hire — book the whole sauna for 2, 3 or 4 hours. This is the natural choice for a birthday, a work outing, a winter-bathing club, or any group that wants the space to itself without sharing the bench with strangers.
• Shared drop-in — turn up (with a booking) and share the sauna with other guests, capped at eight people at a time. This is the cheaper, more sociable option if you’re solo or in a pair.

Poseidon, the sailing vessel, is chartered separately for groups of up to twelve and is priced independently of the sauna sessions — get in touch with Fjordtokt directly through fjordtokt.no for current rates, since boat charter pricing varies by duration and route in a way that isn’t published as a simple rate card.

What It Costs

Fjordtokt sits in the mid-to-premium range for Oslo saunas. Drop-in sessions start from 200 NOK per person for one hour, rising to around 400 NOK for two hours. Private hire of the sauna is priced per vessel rather than per head, running from roughly 2,000 NOK up to 2,800 NOK depending on how long you book it for — a model that rewards larger groups, since the cost is split across everyone in the booking rather than multiplied per person.

Getting There

Sollerud is on Oslo’s west side, roughly a five-minute walk from Lysaker station — an easy stop on the local train or bus network, and a lot less crowded than the queues that can build up at Aker Brygge on a sunny evening. If you’re coming for a boat charter, confirm your departure point when you book, since some Poseidon tours run from Aker Brygge instead of Sollerud.

Good to Know Before You Book

Book ahead, particularly for weekend evenings and private hire — this is a small, independent operation with limited slots per session, and Oslo’s floating saunas fill up fast. If you’re planning a group celebration, pair the sauna with a food and drink package; see our guide to saunas with food and drinks in Norway for what’s typically on offer at venues like this one. And if you’re weighing Fjordtokt against other private-hire options across the city, our guide to private sauna booking in Norway covers group sizes, lead times, and what to expect at checkout.
