A guide to Oslo hotel spas, pools and saunas

Good to know

Swimwear is mandatory in mixed-gender spa areas across Norway. 

Most hotel spas in Oslo enforce a minimum age of 16 and at Bristol Spa the limit is 18. Grand Hotel allows children as young as 5, but only during a short morning window (08:00 to 10:00) with an accompanying adult.

At properties that charge for spa access, booking ahead is almost always required. Several of the spas operate at limited capacity and is open for outside guests as well. Turning up in your robe without a reservation is a recipe for disappointment, especially on weekends.

Hotels with spa and treatments

Hotel Bristol (Bristol Spa)

Bristol Spa opened in December 2025 in a purpose-built space next to Hotel Bristol, connected to the hotel's third floor so you can walk directly from your room in a robe without passing through the lobby. There's also a street-level entrance for non-hotel visitors.

The spa stretches across three floors and draws heavily on Moorish design, with warm terracotta tones and mosaic tiling. The second floor has a traditional dry sauna, an infrared sauna, and a snow room for cold contrast therapy, along with hot and cold plunge pools. A sauna master runs aufguss sessions through the day, which involves essential oils on the sauna stones and rhythmic towel-waving to distribute the steam. 

The third floor has a pool, but it's rather small, more like a relaxation pool rather than a lap pool, surrounded by Moorish arches and soft lighting, along with a rainwalk shower where natural stones massage the soles of your feet. There´s also a private rhassoul room for Moroccan clay treatments with steam and mineral-rich mud.

This is a full service spa with menus including traditional massages, signature body treatments, and facials. Mask buffet stations let you self-apply hair and face masks between thermal sessions, which is something most spas don't offer.

Spa access is not included in the room rate though. Hotel guests get a small discount and pay from 795 NOK while non-hotel visitors pay from 895 NOK. The main benefit you get from staying here is the ability to walk straight from your room. Packages that bundle spa entry with accommodation exist (the Spa Package and Signature Stay Package), so check those if the spa is your main reason for booking here.

The 18-year age limit is absolute.

Sommerro (Vestkantbadet)

Sommerro's wellness offering is split across two different spaces, with different access rules.

Vestkantbadet is the main spa floor, 1,400 m² built around the restored 1932 public bathhouse. The pool is of a decent size for swimming (12.5m × 10m) and sits under an original mosaic wall, with Art Deco changing cabins that have been restored from the originals. There are separate men's and women's saunas and shower areas flanking the pool. Off to one side, the former Roman bath has been converted into a cold plunge pool. Vestkantbadet also houses treatment rooms with a full spa menu.

The rooftop has a separate year-round heated pool and a sauna with a large window overlooking the terrace and the Oslo skyline.

While Vestkantbadet pool and sauna access is included for all hotel guests at no extra charge, the rooftop pool and sauna is only included for suite guests and selected wellness packages. If you're in a standard room, you can sometimes book rooftop access when slots are available, but it's not guaranteed and it costs extra.

The gym is included for all guests, is large and excellent, amongst the best you will find in a hotel, with personal trainers on staff.

If you're not staying at the hotel, you can buy a day pass for the pool and sauna at 295 NOK, or memberships for regular use. Since the facilities are not limited to hotel guests, during peak periods this can mean a crowded pool.

The age limit is 16. Towels are provided; robes and slippers are available for rental.

Grand Hotel Oslo 

The spa occupies a single floor at the Grand Hotel and creates a deliberately moody atmosphere around its wellness pool. Birch tree trunks line the pool perimeter, and blue-purple LED lighting is designed to simulate a twilight forest. The pool itself is heated but is not sized for swimming..

The thermal options alongside the pool include a dry sauna, a steam bath, and an infrared cabin. A separate fitness centre on the seventh floor has TechnoGym equipment, free weights, and floor-to-ceiling windows with city views. The gym is decent, and they can arrange personal training sessions.

Treatment rooms (including a couple's room) offer facials and body treatments. 

Hotel guests over 16 pay 250 NOK per visit on a drop-in basis, but it's strictly offered on a drop-in basis. Reservation is not possible, which makes this less of a reliable option if the spa is a major reason for your booking.

Non-hotel visitors can use the facilities on a drop-in basis, but access depends entirely on whether there's available space.

A bathrobe and slippers are provided in your room. The capacity issue is the main drawback here, as the space is compact, and the Grand Hotel is a large property. 

The Thief (Thief Spa)

The centrepiece of The Thief Spa is a 12-metre heated pool with counterflow for stationary swimming and colour-therapy lighting. There's a Finnish sauna, a steam room with a salt crystal centrepiece (hamam-style), and what The Thief calls "Sensory Sky" showers that cycle through different temperatures and light patterns.

Hotel guests pay about 300 NOK for a 90-minute spa session, or 200 NOK if they've booked a treatment Monday through Thursday. On public holidays, the rate jumps to 600 NOK. External guests pay about 600-700 NOK depending on the day.

The gym is separate from the spa and free for hotel guests around the clock.

The minimum age is 16.

Hotels with pool and/or sauna included free

None of these hotels offer on-site spa treatments, but what they do offer is a gym, sauna and maybe a pool that come with the room at no extra charge.

Amerikalinjen

Amerikalinjen doesn't have a pool, but instead it has one of the best hotel saunas in Oslo. A large Finnish sauna that comfortably fits multiple people without feeling cramped, finished in light wood. Next to the sauna are heated mosaic reclining beds and showers calibrated to replicate the cold of the Nordic sea for contrast therapy.

The gym is genuinely excellent, one of the best hotel gyms in the city. It´s open 24 hours, stocked with Technogym cardio equipment, a slat treadmill, rowing machines, and a full free-weight section.

Everything is included in the room rate, and guests have the facilities for themselves, as the facilities are not open to non-guests. The sauna is open mornings and late afternoon through evening, with a midday break.

It's worth being aware that the wellness area entrance is in the basement, right next to the queuing area for Club Gustav, the hotel's live jazz venue. On concert nights, you might pass through a crowd of dressed-up concertgoers while wearing a robe and slippers.

Clarion Hotel The Hub

The Hub has an indoor (plunge) pool, a dry sauna, a menthol steam room, and a gym on the lower ground floor. All of it is free for hotel guests, but this also means that it will be crowded at peak hours as the hotel is huge, actually the largest hotel in Oslo.  Early mornings or late afternoons/evenings are best to avoid the worst crowds.

The menthol steam room is the standout: it infuses heavy steam with concentrated menthol, which clears the airways and has a sharp, refreshing effect.

The gym is divided into cardio and weights zones, equipped with TechnoGym machines including a full squat rack, SkillMills, cycling bikes, rowing machines, and a functional training area with kettlebells and medicine balls.

Radisson Blu Plaza

The Radisson Blu Plaza has put its pool, saunas, and fitness room high up on the 34th to 37th floors, which means you get city panorama views from the sauna and the gym. 

The pool has a counter-current system that lets you swim continuously without hitting the wall, which partially compensates for the limited size.

All facilities are free for hotel guests and not available to non-guests.

Radisson Blu Scandinavia

The Radisson Blu Scandinavia has "The Lagoon" on the lower level, which consists of an indoor pool, sauna, and gym, and all included for hotel guests. The pool is a decent size for a hotel, swimming is possible, but the sauna is quite basic and the space feels somewhat dated compared to the newer properties on this list. The gym is well-equipped and operates from 05:00 to 23:00 daily. With 497 rooms, the pool area can get crowded at peak hours.

Outside the city centre

Scandic Holmenkollen Park

Scandic Holmenkollen Park is up on the hill above Olso, 350 metres above sea level, a 30-minute T-bane ride from Oslo Central Station, next to the Holmenkollen ski jump. The hotel reopened not long ago after extensive renovation with a pool, sauna, steam room, cold showers, and a relaxation area with daybeds. The gym is enormous, and easily one of the largest and best hotel gyms in the Nordics.

The spa operates under somewhat unusual rules. There is no advance booking: entry is drop-in only, with a maximum of 12 people in the spa at any time, and once it's full, you have to wait. The spa is even closed on Sundays and Mondays. 

Hotel guests pay from 195 NOK per visit and the age limit is 16.

You wouldn't stay here if your plan is sightseeing around Oslo. It's a choice for travellers who are staying at Holmenkollen for the skiing, the hiking trails into Nordmarka, or the views, and want a sauna and pool to come back to at the end of the day. The 12-person cap and no-booking policy make it unpredictable if the spa is your primary motivation.
