The sauna at Immersion Spa, in the city of Palo Alto in the state of California, is part of a Korean-style spa facility that offers both dry and steam saunas alongside other amenities like hot tubs and cold plunges. The dry sauna operates at around 170°F and features herbal infusions, though some guests note it could be warmer. The facility maintains a quiet, meditative atmosphere in the sauna areas, with separate men's and women's sections, and guests are encouraged to rotate between the different heat experiences for optimal benefits.
