Frost And Float Spa (Cryotherapy , Float Therapy, Infrared Sauna)

Frost and Float on Washington Street in Newton assembles three modalities that work well in sequence: cryotherapy for the cold, infrared sauna for the heat, and float therapy for what comes after.

Whole-body cryotherapy involves a brief exposure — usually two or three minutes — to air chilled far below anything a cold plunge reaches. It is a sharper, drier cold than immersion, and practitioners use it for inflammation and recovery. Paired with infrared sauna, which warms the body directly and allows a longer, gentler heat session than a traditional room, it produces the contrast effect without either extreme lasting long.

Float therapy sits apart from both. A tank of Epsom-saturated water at skin temperature, in darkness and silence, removes sensory input rather than adding to it, and works as a wind-down after the contrast work.

Newton’s Washington Street corridor runs through Newton Corner and Newtonville with reasonable parking and Commuter Rail access. Each modality is booked separately and floats in particular need reserving ahead, since a tank serves one person at a time.

Each modality is priced and booked separately, and packages combining them generally cost less than individual sessions.
