STU Sauna (Brattøra)

We are passionate champions of spa and wellness tourism, and visiting the floating sauna at Brattøra remains one of our favourite ways to experience Trondheim's harbour — an iconic mix of wood-fired heat, crisp sea air and a brisk fjord dip. If you searched for "floating sauna trondheim" or "badstu trondheim", this page explains exactly what makes the STU floating sauna special and why it's worth a click, a booking and a plunge.

Why the floating sauna at Brattøra is unmissable

From our own visits we can say the floating sauna brings together three things Trondheim does brilliantly: dramatic water-front views, uncomplicated Norwegian design and a healthy obsession with thermal contrasts. The sauna sits on a stable pontoon in Brattøra harbour, giving you 180° views across the water and quick, safe access to a cold-water ladder for that classic hot-cold experience. It’s intimate, photogenic and reliably restorative — perfect for locals, visitors and anyone looking for a memorable badstu trondheim moment.

The floating sauna experience in detail

• Atmosphere: Wood-fired heat, natural timber interiors, warm bench seating and a soft glow from the stove. The smell of pine and smoke is part of the charm.
• Temperature & capacity: Stoves are typically pushed to 80–95°C for a clear hot session; the sauna comfortably fits 6–10 people depending on booking type.
• Cold plunge: A sturdy ladder and platform give easy access to the harbour water; daily water temperatures vary seasonally — from invigorating near-freezing in winter to cool and refreshing in summer.
• Aufguss & rituals: We’ve seen guided Aufguss (steam infusion) sessions offered at select times — these add scent, a short ritual and increased humidity for a more intense, social sauna.

What makes the Brattøra floating concept special

The floating sauna is not just a room on the water — it’s a deliberate experience design. Being on the pontoon means the city and the sea are part of the session. Boats and the harbour skyline form a moving backdrop while the water at your feet invites an immediate cooldown. Compared with shore-based saunas, this floating badstu gives an extra sensory edge: the small swell, the open horizon and the ever-present smell of sea salt.

What to expect on arrival

• Meeting point: Brattøra harbour near the pier; look for the wooden pontoon and our STU signage.
• Check-in: Arrive 10–15 minutes early to change, stow belongings and get safety instructions.
• Facilities: Changing area, benches, life jackets and a small dry storage for phones. Towels and disposable slippers are often available for hire if you prefer not to bring your own.
• Safety briefing: Staff will cover ladder use, seawater conditions, and first-aid basics. Lifebuoys and a crew member are on-site during public sessions.
• What to bring: Swimwear (optional for traditionalists but recommended for public sessions), towel, water bottle, flip-flops and a warm layer for after the session.

Recommended routines for first-timers and regulars

We recommend structured rounds to get the most from a floating sauna session:

1. Warm-up (8–12 minutes): Enter the sauna, sit back, drink water and allow your body to heat gently.
2. First cooldown (1–2 minutes): Step outside, breathe fresh harbour air and if comfortable, take a quick ladder dip into the fjord.
3. Second round (6–10 minutes): Return to the sauna for an Aufguss or a more intense sweat.
4. Longer cooldown & recovery (10–20 minutes): After two to three rounds, finish with a longer rest ashore or on the pontoon, hydrate and enjoy the view.

For newcomers, two rounds with short dips is an ideal intro. Advanced users may do three or four rounds with longer cold plunges between each. Always listen to your body and pace yourself.
