Purify is a locally female-owned infrared sauna studio in Richmond's West End, operating for over a decade. Guests book 40-minute sessions in a private suite with an infrared sauna, and every suite now includes medical-grade red light therapy and adjustable chromotherapy lighting. A single session costs $39. Cold plunge is offered only at the Short Pump branch, not here. Open Monday to Thursday 9 AM to 8 PM and Friday to Sunday 10 AM to 5 PM.
