How to Book Sauna in Oslo (Quick Guide)
Oslo has three types of sauna booking: online reservations for premium experiences (KOK, SALT, private saunas), drop-ins at public pools (Tøyenbadet, Frognerbadet), and membership-based access (gyms). Which type you choose depends on how spontaneous you are, your budget, and what experience you're seeking.
For first-timers, I recommend starting with an online booking at KOK or SALT - these floating saunas are quintessentially Oslo: you get 2-2.5 hours of wood-fired heat, direct access to Oslo fjord's 5-8°C water (summer slightly warmer), and views of the Opera or Sørenga. Price 250-295 NOK. Yes, pricier than public pools (85 NOK), but the experience is unique. You're not just booking sauna - you're booking Nordic ritual with water-and-heat dance going back centuries.
Online Booking Step-by-Step
- Choose sauna type: Floating (KOK, SALT) for iconic experience, private (entire sauna to yourself/group) for special occasions, or public (Tøyenbadet) for affordable drop-in.
- Check availability: Go to operator's website (kokkokko.no for KOK, saltogsauna.no for SALT). Weekends usually booked 5-10 days ahead, weekdays 2-4 days.
- Select time: Mornings (8-10am) = fewer people, beautiful sunrise. Afternoons (2-4pm) = most popular, may be full. Evenings (8-10pm) = romantic, stars (winter).
- Pay online: Vipps, card (Mastercard/Visa), some accept Apple Pay. Get confirmation via SMS/email with details and QR code.
- Prepare visit: Bring towel (or two), water, bathrobe (recommended for outdoor cooling). Arrive 10 minutes early to find location and change if necessary.
🧖 Pro tip from an Oslo local:
Tuesdays and Wednesdays are gold standard for booking - fewest people, easier to get desired time, same price as weekends (but calmer experience). Avoid Saturdays 2-6pm if you don't like crowds. And always, always book morning times if weather uncertain - operators rarely cancel early slots (wind conditions usually worsen throughout day).
Same-Day & Drop-In Saunas in Oslo
Not all sauna experiences require advance booking. In fact, many Oslo locals use drop-in public pools as their regular sauna routine - affordable, low-threshold, and you can go anytime (within opening hours). Here are your best same-day options:
Public Pools (Always Drop-In)
- Tøyenbadet: 85 NOK (pool + sauna included). Located at Tøyen metro. Closed Mondays. Open Tue-Fri 6am-7pm, Sat-Sun 8am-5pm. Least crowded weekdays 10am-2pm. Sauna is small but authentic Norwegian style (typically 70-80°C, stone wall, wooden benches). Accepts cash and card.
- Frognerbadet: 120 NOK. Near Vigeland Park (tram 12 to "Vigelandsparken"). Open Mon-Fri 6am-7pm, Sat-Sun 8am-6pm. Larger than Tøyenbadet, better sauna facilities (two saunas: one dry 85°C, one steam 60°C). Popular with families. Also has outdoor pool summer.
- Vestkanbadet: 140 NOK. At Vestli metro (bit outside center, but worth trip if you want to avoid tourists). Spacious sauna, local Oslo people, chill vibe. Open weekdays 6am-8pm, weekends 8am-6pm.
Gyms with Day Passes
Several Oslo gyms offer day passes/drop-ins that include sauna access (150-250 NOK). This is middle ground between public pools (cheaper but simpler) and premium floating (pricier but more spectacular). Gym saunas are usually modern, clean, and less crowded than public baths. Best options:
- SATS Colosseum: 200 NOK day pass (sauna + gym + pool). Central at Oslo S. Sauna is large (8-10 people), modern, infrared heat. Open 6am-11pm weekdays.
- Fresh Fitness Torggata: 150 NOK drop-in. Smaller sauna but rarely full. Good for spontaneous visits after work. Open 24/7 (staffed 7am-8pm, self-service otherwise).
- Elixir Grünerløkka: 180 NOK day pass. Bit more premium than Fresh, includes steam room + dry sauna. Located in trendy Grünerløkka (tram 11/12/13 to "Olaf Ryes plass").

Planning bachelor party, birthday, or corporate event? Oslo has several private sauna options where you book entire sauna for your group (6-12 people typically). These are premium experiences - pricier per hour, but when you split cost it actually becomes reasonable per person, and you get exclusivity worth it for special occasions.
KOK Private Booking
Entire floating sauna to you and friends (8-12 people). 2400-3000 NOK for 2 hours (200-250 NOK per person if full group). Includes: exclusive access, can order food/drink boxes (sushi, tapas, beer/wine delivered to sauna), private fjord swimming, towels. Booking: contact KOK directly via email (booking@kokkokko.no) or phone. Book ahead for weekends, but same-day bookings often available on weekdays. Perfect for: bachelor parties, birthdays (especially adults 30-50 wanting something different than bar crawl), team-building.
Bademaschinen Mobile Saunas
1500-2500 NOK/hour for 6-8 people. Unique concept: mobile floating saunas that can be ordered to different locations around Oslo fjord - not just Sørenga, but also private beaches, seaside cabins, etc. More intimate than KOK (smaller sauna), but also more flexible. Booking: bademaschinen.no, fill out request form with desired date/location. They respond within 48h with availability. Book ahead for summer weekends, but weekdays often available same-day.
Hotel Spas
The Thief Spa (Tjuvholmen): 800-1200 NOK/hour for private booking of entire spa area (sauna + steam room + jacuzzi + pool). Extremely luxurious - premium bathrobes, designer products (Molton Brown), discreet service. Perfect for romantic couple experiences or high-end corporate events. Combine with dinner at Thief Restaurant for ultimate luxury evening. Booking: call +47 24 00 40 00 or email spa@thethief.com. Book 3-4 weeks ahead.
💎 Insider tips for private bookings:
- • Book Monday-Thursday for 20-30% better price than weekends (KOK/Bademaschinen adjust prices based on demand).
- • Always ask about food/drink policy before booking - some allow BYOB, others have catering (often cheaper to bring own).
- • For large groups (12+), consider splitting into two bookings (e.g. one morning slot + one evening slot) instead of trying to squeeze everyone in simultaneously.
Booking Etiquette & Practical Tips
What to Bring
Essential for all sauna types: Towel (or two - one to sit on in sauna, one after shower), water (0.5-1L - you sweat enormously), bath shoes/flip-flops (most places have wet floors). Highly recommended for floating saunas: bathrobe (you go in/out multiple times for fjord cooling, awkward to stand naked on deck if other boats pass), small waterproof bag for phone/keys (sea spray), sunglasses (reflection from water can be intense summer days).
Arrival Timing
Floating saunas (KOK, SALT): arrive 10-15 minutes before slot start. This gives time to find sauna (Sørenga dock can be confusing first time), change in locker room, and get brief intro from hosts. Don't arrive more than 20 minutes early - hosts need time to prepare between groups. Public pools: arrive anytime (drop-in), but fewest people weekdays 10am-2pm or late evening 6-7pm before closing.
Cancellation & Changes
KOK: free cancellation until 24h before, then full price. Can change time via "My booking" on website (free if 48h+). SALT: free until 48h before, 50% fee 24-48h, 100% under 24h. The Thief/hotel spas: 72h cancellation notice common. Important: if you get sick or weather becomes extreme (thunder, strong wind), call operator directly - they're often flexible and offer voucher for future visit instead of refund.
