Santa Monica Gym With Sauna Open 24/7: 24 Hour Fitness

24 Hour Fitness Santa Monica Super-Sport, at 2929 31st Street near the Santa Monica Airport, is open 24 hours a day, seven days a week, and it has a sauna, a steam room and an indoor lap pool. That combination is rare on the Westside, where most gyms with a sauna close by 10pm. The club page notes that access to these amenities depends on your membership type, so the plan you pick matters as much as the location.

The club page announces that its transformation is complete, listing expanded workout space, a brand-new turf zone and upgraded equipment. The newly upgraded areas named on the page are a new turf area, a Recovery24 area, a Premium Fit24 area and select new equipment. Super-Sport is 24 Hour Fitness's label for its larger clubs, the ones that usually carry a pool and the full set of wet amenities.

The location is quieter than the beach end of town. The club sits in the southeast corner of Santa Monica near the airport and Ocean Park Boulevard, among offices, apartments and light industrial buildings. Being away from the beach also means a parking lot rather than metered street spaces, which matters for anyone coming straight from work.

The amenity list names an indoor lap pool, a steam room and a sauna, together with TRX suspension training, free weights, cardio equipment, group exercise and group cycling. Towel service, Recovery24, Premium Fit24 and the Nutrishop counter are marked as extras that may carry fees.

The appeal of a 24/7 club with a sauna is timing. A swimmer who finishes a late shift can do laps at midnight, sit in the sauna and still be home before 1am. Try a contrast routine of ten minutes of easy laps, ten in the sauna and a cool shower, repeated twice. Finish in the steam room only if you are well hydrated, because the two hot rooms back to back drain you quickly.

The single rule that matters most is printed under the amenity list: access is based on membership type. The plan comparison table on the club page lists the lap pool, sauna and steam room among the features that differ by plan, so ask the front desk which current tier includes them before you pay. A cheaper plan that only covers the weights floor will leave you outside the hot rooms.

The chain has renamed its plan tiers during 2026, and the price list on this club's page has changed with them, so the useful step is to compare the sauna-inclusive tier with your weekly use. If you will swim and sauna three times a week, the higher tier pays for itself against a boutique sauna studio, where one session can cost more than a month here.

The chain's free-pass terms on the club page explain how trials work across its clubs: the pass starts on your first day of use, requires photo ID and is for local residents only. Guests must be at least 18, or 12 with a parent, and anyone who was a member or guest in the previous six months is not eligible.

Use a trial to check the pool and sauna at the hour you would really go. For night owls, that means one visit after 11pm. For early risers, try 5:30am, when many members come in before driving across the Westside to work. Weekday evenings from 5pm to 8pm are the most crowded, with classes, cycling and the pool lanes all busy at once.

Overnight hours change how a gym feels. Late at night there are far fewer people around, so keep your locker key or padlock with you, rack your weights and leave the sauna as you found it. Do not use the sauna alone if you have been drinking or feel unwell, since there are fewer people around to notice a problem.

Phones and cameras do not belong in the locker rooms or hot rooms. Bring flip-flops for the pool deck and the showers, and a second towel for the sauna bench if your plan does not include towel service. These small habits matter more here than at a busy daytime club, because the night crowd is small and regulars notice.

This club is built for people with irregular schedules: nurses, restaurant staff, film crews and anyone who trains after midnight. It is also a solid choice for swimmers who want a sauna after laps without paying private-club prices on the Westside.

Choose somewhere else if you want a spa-style experience with eucalyptus steam, cold plunges and attendants. Private clubs nearby, such as Bay Club Santa Monica in the Water Garden office campus, offer a calmer locker room and a sauna but close in the evening and cost far more. For a dry sauna alone, infrared sauna studios in Santa Monica and Brentwood sell single sessions without a membership.

The club is about a ten-minute drive from the Pier and Main Street, and parking is far easier than near the beach. The Metro E Line stops at 26th Street/Bergamot to the north, and Big Blue Bus routes run along Ocean Park Boulevard nearby.

After a daytime session, walk south to Clover Park, which has open lawns, sports fields and views of planes on the Santa Monica Airport runway. The Bergamot Station arts complex, a group of galleries in former rail buildings near the Expo line stop, is a short drive north. Main Street cafes make a good breakfast stop after an early swim.
