Mountainside Fitness Ahwatukee
4820 E Ray Rd, Phoenix, AZ
Mountainside Fitness Ahwatukee on Ray Road near 48th Street is the chain's newest-built club in the Ahwatukee Foothills, and the one in this group with the fullest heat-and-cold menu: a locker-room steam room and dry sauna included with the base membership, plus infrared sauna cabins and cold plunge tubs that the company runs at 48-62°F in the recovery area, bundled with red-light therapy as a Wellness add-on from $20 a month. Around them is a standard Mountainside floor: free weights and machines, cardio with personal screens, a cycle studio, Serenity yoga and Ignite group-fitness studios, a basketball/pickleball court, a recovery massage chair, an MCafé smoothie bar and a kids' club. Memberships are month-to-month from about $48.85 with no enrollment fee, and the non-member entry point is the chain's free 5-day pass requested online (the club may ask that it be used with a member). Plan on a short cold plunge of a few minutes after the sauna; the tubs are communal, so bring swimwear, and towels are free. The club runs 4:30 a.m. to 11 p.m. Monday to Thursday, until 9 p.m. Friday, and 6 a.m. to 9 p.m. on weekends. For the price it is one of the cheapest places in the valley to build a regular sauna-plunge habit, with the trade-off that the plunge is a gym add-on rather than a guided bathhouse ritual.
