Best Saunas in St. Louis, MO
St. Louis is a gym town with a contrast habit: 9 of our 17 verified venues are gyms, but the dedicated studios are strong — FLOAT STL has been pairing infrared sauna with cold plunge since 2015, longer than almost anyone in the country. Twelve venues run infrared, 7 offer cold plunge, and 8 of 17 publish pricing, making this one of the easier markets to shop on price.
The contrast specialists
Midtown
FLOAT STL – Midtown
Serving St. Louis since 2015 — a genuine veteran in a market full of newcomers — pairing infrared sauna heat with cold plunge immersion, plus float therapy and massage. Cold plunge sessions start from $20, and there's an unlimited contrast therapy membership at $325/month for the committed. A second location in Maryland Heights covers the west county.
Central West End
Stretch U – Central West End
An assisted-stretch studio two blocks from BJC Medical Center with a full recovery suite: infrared sauna, cold plunge, red light therapy, and compression. The $20 intro recovery session (plunge, contrast, red light, sauna) is the cheapest structured way to try the full hot-cold stack in the city.
Ellisville
Salty Spa
A holistic day spa in West County offering infrared sauna paired with cold plunge, plus a halotherapy salt room, red light, compression, ionic foot detox, and an oxygen bar. The spa-day version of contrast therapy — the broadest amenity menu of any single venue in the metro.
Crestwood
Pūr Sweat – Infrared Sauna Studio
A dedicated, woman-owned infrared sauna studio in Crestwood also offering halotherapy in its SALT Booth, with private sauna sessions by appointment. The Sweat Club membership saves $15 per sauna session — the neighborhood-studio pick for people who want infrared without the gym or the spa markup.

An athletic country club whose official amenities page lists a cedarwood sauna, locker-room saunas, and eucalyptus steam rooms, plus indoor and outdoor whirlpools. The best traditional-heat option in the metro if you want sauna as part of a full club routine.
