Why Floating Saunas Are Special
Floating saunas sit right on the Oslo Fjord, built on platforms or boats. The setup is simple: you heat up in the sauna, then jump straight into the fjord to cool down. No walking to a separate cold plunge—just open the door and dive in.
Over the past few years, floating saunas have become popular in Oslo. Both locals and visitors use them year-round, though winter (when the water hits 2-5°C) is when you get the full Norwegian experience.

- Heat session: Spend 10-15 minutes in the sauna (80-100°C)

- Rest: Relax on the deck or inside for 10-15 minutes

Best Times to Visit
Floating saunas in Oslo operate year-round, but each season offers a unique experience:
Summer (June-August)
The most popular time with long daylight hours and warmer water temperatures (15-18°C). Book well in advance as spots fill quickly. Evening sessions around sunset are magical.
Winter (December-February)
The most authentic Nordic experience. Water temperatures drop to 2-5°C, creating an intense contrast with the hot sauna. Many consider this the true Norwegian sauna experience. Less crowded than summer.
Spring/Fall (March-May, September-November)
Moderate water temperatures (8-12°C) and fewer crowds make these ideal seasons for first-timers. Weather can be unpredictable, but the experience is equally rewarding.

Frequently Asked Questions
Is it safe to swim in the Oslo Fjord year-round?
The Oslo Fjord is generally clean and safe for swimming. In winter, cold plunges should be brief—start with 10-30 seconds and build up slowly. If you have heart conditions, high blood pressure, or other medical concerns, talk to your doctor before trying cold water immersion. The shock of cold water can be dangerous for some people.
Do I need to know how to swim?
You should be comfortable in water. Most floating saunas have ladders and you're not going far—just jumping in and climbing back out. But if you're not a strong swimmer, tell the staff when you arrive. They can advise on the safest way to do it.
Can I go if I'm pregnant?
Talk to your doctor first. Pregnancy and saunas/cold water immersion is something you need medical advice on—it depends on your specific situation and how far along you are.
Are floating saunas suitable for children?
Most floating saunas welcome children when accompanied by adults. However, many have age restrictions (typically 12+) due to safety concerns. Always check with the specific venue.
What if I've never done a cold plunge before?
Start slow! Your first plunge can be just 10-15 seconds. Focus on controlled breathing and gradually increase your time with each session. The shock lessens significantly after your first few attempts.
How long should I stay in the sauna?
Beginners should start with 5-10 minutes and work up to 15 minutes max per session. Listen to your body—if you feel dizzy, lightheaded, or uncomfortable, exit immediately.
