About Soak & Sage

A social bathhouse on Lake Washington selling timed two-hour access to a thermal circuit: a hot soaking pool, cold plunge, two distinct saunas (Finnish cedar and a Temazcal), a steam room and a sub-freezing snow room. Deliberately operated as a conversational rather than silent space, with massage, facials and a med-spa arm alongside.
