Plunsana

Sauna and cold plunge studio in St. Petersburg, Florida: dry barrel saunas at 185 to 195°F, cold plunges at 39 to 51°F, guided classes and walk-ins daily.

Plunsana is built around contrast therapy: a round in the sauna, a few minutes in cold water, then rest, repeated three to five times. The studio has indoor and outdoor spaces, with barrel saunas and cold plunge tubs set in a turf courtyard under shade sails and more plunges and a sauna inside. Red light panels and a breathwork area round out the visit.
