This unique sauna floats directly on the Oslo Fjord and offers an authentic Nordic sauna experience combined with cold plunge in saltwater.

Perfect for those wanting to experience authentic floating sauna with urban energy.
SALT: Premium Fjord Sauna with Full Wellness Concept
SALT at Langkaia is Oslo's largest and most comprehensive floating sauna concept. This is more than just a sauna - it's a complete wellness and cultural center built from wooden salt (hence the name SALT). The facility includes multiple saunas of various sizes and temperatures, an outdoor ice bath house, lounge areas, restaurant, bar, and an amphitheater for events. The largest floating sauna has panoramic views over the fjord and can accommodate up to 40 people. SALT focuses on a more holistic wellness experience with a calmer atmosphere than KOK, and also offers yoga classes, workshops, and cultural events. Prices are usually 250-350 NOK for standard drop-in, with memberships and season passes available. The facility is family-friendly with specific family hours, but also has adults-only times for a more relaxed experience. Open year-round. Ideal for those wanting a premium fjord sauna experience focused on wellbeing, good food, and cultural experiences in addition to sauna and cold plunge.
Other Floating Saunas and Waterfront Alternatives in Oslo
Beyond KOK and SALT, there are several lesser-known but equally authentic floating saunas in Oslo. Aker Brygge sauna is an intimate floating sauna at Aker Brygge with room for about 8-10 people, perfect for a quieter fjord sauna experience. Seabin Sauna at Frognerkilen offers private rentals of floating saunas for groups of 6-12 people, ideal for private events or corporate gatherings. Several waterfront saunas along the fjord that aren't technically floating but are located right by the water with direct access to sea swimming: Huk sauna (Bygdøy), Langvikbukta sauna (Nesodden), and Kadettangen sauna (Sandvika). These offer similar experiences with sauna + cold plunge, but without the floating platform. Prices vary from 150-300 NOK for drop-in. Some require membership or advance booking. For those wanting to explore beyond the big names, these alternatives offer more intimate, less crowded experiences with the same magical combination of hot sauna and cold fjord swimming.
