Bywater Sauna

Bywater Sauna runs reserved sauna sessions in Seattle at waterfront spots, with locations at Alki Beach and Golden Gardens, a dockside spot on Lake Washington off Lakeside Avenue, and a seasonal spot at Old Stove in Ballard. Guests book a limited-capacity session of 60 or 75 minutes online, then cycle between the sauna and cold water or cool air at their own pace. Drop-in sessions cost 35 dollars on weekdays and 40 dollars on weekends. A monthly membership costs 100 dollars and allows one session per day, with one free guest pass each calendar month. Guests bring their own towels and can rinse at outdoor showers at the public bathhouses.
