Bywater Sauna

Bywater Sauna runs sauna sessions beside open water at pop-up locations around Seattle, including the Alki Beach boardwalk and Golden Gardens. Guests reserve a spot online for a 60 or 75 minute session, then cycle between the sauna and the cold water or cool air at their own pace. Drop-in sessions are listed at 35 dollars on weekdays and 40 dollars on weekends. A monthly membership at 100 dollars covers unlimited sessions, up to one per day, and includes one free guest pass each month. Guests bring their own towels and sit on them in the sauna. Outdoor rinse showers are available at the public bathhouses, and shelves and hooks hold belongings outside the sauna.
