Alchemy Springs

What you need to know

Alchemy Springs is a sauna and cold-plunge garden on Lower Nob Hill. The contrast therapy cycle (hot sauna, cold plunge, rest by the fire) is the core of every visit, and most sessions run about two hours.

What to expect

The garden is about 2,500 square feet and contains a 40-person circular sauna with tiered seating and immersive lighting, plus cold-plunge tubs, rain showers, thermal benches, and a fire pit. Long-term plans include in-ground soaking pools, a second 200-degree sauna, a greenhouse lounge, and a tea bar.

A drop-in session costs about $57 for two hours. An intro 3-pack ($99) brings the per-visit cost down. The space also runs yoga, sound baths, meditation, and themed evening sessions.

Practical details

Book your session through the website. Walk-ins aren’t guaranteed. Robes are provided. Bring a swimsuit; the space is communal. Most of it is outdoors, so dress for the walk in.
