Alchemy Springs & Sauna Garden is a modern thermal bathhouse and social wellness club in San Francisco, featuring the largest known outdoor sauna in the country. The spa's core offering is a powerful contrast therapy experience, where guests alternate between a large, spacious dry sauna and two cold plunge pools. The sauna is noted for its size, fitting around 30 people, and its clean, thoughtfully designed environment with natural light from skylights. Spa-goers describe the guided contrast therapy sessions, led by facilitators like Sina and Nahal, as transformative. These sessions combine the sauna and cold plunge with guided meditation and breathwork, helping guests move through discomfort, regulate their nervous system, and achieve notable mental clarity and mood benefits. The experience is described as an intense, efficient workout for both mind and body that fosters mental resilience. Beyond the thermal cycle, the outdoor spa area serves as a tranquil sanctuary, complete with outdoor showers and heated benches for relaxation between rounds. The spa provides a complimentary tea bar where guests can craft custom blends. The atmosphere cultivates a beautiful community vibe, offering a social sauna experience that feels like a resort escape, allowing city noise to disappear. The venue also hosts a variety of events at its sister property, Alchemy House, including yoga, breathwork, sound healing, and art exhibitions. The full 14,000 sq ft flagship experience is in development, with the current Sauna Garden offering a preview during its soft launch.
