Best Oslo hotels with pool, spa or sauna

Good to know

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

Age limits are strict at some of the properties. Most hotel spas in Oslo enforce a minimum age of 16. Bristol Spa is 18, no exceptions. Grand Hotel allows children as young as 5, but only during a narrow morning window (08:00 to 10:00) with an accompanying adult.

At properties that charge for spa access, booking ahead is almost always required. The Grand Hotel and The Thief both operate on limited capacity, and turning up in your robe without a reservation is a recipe for disappointment, especially on weekends.

Hotels with spa 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 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 arched niches, warm terracotta tones, and mosaic tiling. The second floor has a classic dry sauna, an infrared sauna built from magnolia wood, and a snow room for cold contrast therapy, along with hot and cold plunge pools. A sauna master runs aufguss sessions through the day, blending essential oils and rhythmic towel-waving to distribute steam. On the same floor there's a hairdresser and a wellness zone offering quick treatments for scalp, skin, and beard.

The third floor has the pool (5.9m × 4m, so a relaxation pool rather than a lap pool), surrounded by Moorish arches and soft lighting. An infrared sauna is on this floor too, along with a rainwalk shower where natural stones massage the soles of your feet, and a private rhassoul room for Moroccan clay treatments with steam and mineral-rich mud.

Five treatment rooms on the fourth floor cover traditional massages, signature body treatments, and facials. Mask buffet stations on several floors let you self-apply hair and face masks between thermal sessions, which is an unusual touch that most spas don't offer.

Spa access is not included in the room rate. Hotel guests pay from 795 NOK. Non-hotel visitors pay from 895 NOK. If you're only booking a treatment and don't want to use the pool and saunas, you don't need to pay the entrance fee. 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.

The 18-year age limit is absolute. No children, no exceptions.

Sommerro (Vestkantbadet)

Sommerro's wellness offering is split across two different spaces, and the access rules for each are different. 

Vestkantbadet is the main spa floor, 1,400 m² built around the restored 1932 public bathhouse. The pool (12.5m × 10m) sits under Per Krohg's original mosaic wall, with Art Deco changing cabins that were hand-sanded back to their original condition during a five-year restoration. Separate men's and women's saunas and shower areas flank the pool. Off to one side, the former Roman bath has been converted into a cold plunge pool paired with an infrared sauna. Vestkantbadet also houses treatment rooms offering massages, facials, body treatments, and cosmetic procedures through a partnership with LaserLegene (medical-grade laser treatments, injectables, digital skin analysis).

The rooftop has a separate heated pool (28°C year-round) and a sauna with a large window overlooking the terrace and the Oslo skyline.

Here's the part that catches people off guard: 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 400 m² gym is included for all guests and is excellent, with personal trainers on staff.

Non-hotel visitors can buy a day pass for the pool and sauna at 295 NOK, or memberships for regular use.

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

The main drawback is that Sommerro runs a dual model: hotel guests, day visitors, and gym members all share the same Vestkantbadet space. During peak periods this can mean a crowded pool.

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, frosted glass doors carry tree motifs, and blue-purple LED lighting is designed to simulate a twilight forest. The pool itself is heated to 30°C and is sized for soaking rather than 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.

Seven treatment rooms (including a couple's room) offer facials, body treatments, and massages. 

Hotel guests over 16 pay 250 NOK per visit on a drop-in basis, and the official advice from the hotel is to reserve well in advance because capacity is limited. Children aged 5 to 15 can access the spa free of charge but only between 08:00 and 10:00, accompanied by an adult.

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

A bathrobe and slippers are provided in your room. The capacity issue is the main drawback here. The space is compact, and the Grand Hotel is a large property. Don't count on a spontaneous visit, especially on weekends or holidays.

The Thief (Thief Spa)

Thief Spa sits in the lower level of The Thief on Tjuvholmen, Oslo's waterfront arts district. The centrepiece 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.

The treatment menu works with premium skincare brands: ZO Skin Health, Natura Bissé, and BABOR. Options run from classic massages and deep-tissue work to clinical facials and body wraps, including pregnancy massage. Several packages bundle spa entry with lunch, brunch, or afternoon tea at the hotel's restaurant.

Hotel guests pay about 300 NOK for a 90-minute spa session (no treatment), 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. No phones or cameras in the spa. Swimwear is required.

Hotels with pool and/or sauna included free

None of these hotels offer on-site spa treatments. 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. What it has instead is one of the best hotel saunas in Oslo: a large Finnish sauna that comfortably fits multiple people without feeling cramped, finished in light wood with a proper electric rock heater. 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 equally strong. It runs 24 hours, stocked with Technogym cardio equipment, a slat treadmill, rowing machines, and a full free-weight section. For a hotel gym, it's one of the best in the city.

Everything is included in the room rate. The facilities are not open to non-guests. The sauna operates on a split schedule: mornings and late afternoon through evening, with a midday break.

One quirk worth knowing: 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'll 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 free for hotel guests. The menthol steam room is the standout: it infuses heavy steam with concentrated menthol, which clears the airways and has a sharp, refreshing effect that's particularly welcome after a day walking in cold weather.

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.

The trade-off is scale. The Hub has 810 rooms and regularly hosts large conference groups and cruise ship passengers. The pool is small, and during peak periods you'll feel it. If you can go early morning or late evening, you'll have a much better experience.

Radisson Blu Plaza

The Radisson Blu Plaza puts its pool, saunas, and fitness room high up on the 34th to 37th floors, which means city panorama views from the sauna and gym. The men's and women's saunas have large glass windows. The fitness room has floor-to-ceiling glass. Even the pool, despite being small, benefits from the elevation.

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.

Two things to know. First, you can't take the elevator all the way: you ride to the 32nd floor and then take the stairs up. There is no elevator access to the wellness floor, which is a real limitation for anyone with mobility issues. Second, the floor-to-ceiling windows in the fitness room create a greenhouse effect. On sunny days, the room heats up significantly, making cardio uncomfortable.

Radisson Blu Scandinavia

The Radisson Blu Scandinavia has "The Lagoon" on the lower level: an indoor pool, sauna, and gym. All included for hotel guests. The pool is a decent size for a hotel, but 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 and a busy conference trade, the pool area can get crowded at peak hours.

Outside the city centre

Scandic Holmenkollen Park

Scandic Holmenkollen Park sits 350 metres above sea level, a 30-minute T-bane ride from Oslo Central Station, next to the Holmenkollen ski arena. The hotel reopened after extensive renovation with a pool, sauna, steam room, cold showers, and a relaxation area with daybeds. The gym is enormous: 1,100 m², one of the largest hotel gyms in the Nordics.

The spa operates under unusual rules. There is no advance booking: entry is drop-in only, with a maximum of 12 people in the spa at any time. Once it's full, you wait. The spa is closed on Sundays and Mondays. Other opening hours vary by season, so check directly with the hotel before planning around a spa visit.

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

This is not a city-centre spa option. 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.
