How Seattle does the sauna
Seattle's sauna scene is built around cold water. Several saunas float on Lake Union or sit in a marina on Lake Washington, and the cold plunge is the lake itself. Others are wood-fired barrel saunas parked on the beach at Alki, Golden Gardens and Lincoln Park, where you walk straight into Puget Sound between rounds. Most of these are small and sell timed sessions, so book ahead, especially on weekends.
For a longer visit, Banya 5 in South Lake Union is a Russian-style bathhouse with a hot parilka and cold plunges, and the Korean spas in Lynnwood follow the jjimjilbang model with gender-separated baths and heated rooms. Olympus Spa is open to women only.
Across the city, infrared studios rent private rooms by the session, often with a cold plunge for contrast.
Before you go
- Puget Sound and the lakes stay cold all year, so the plunge is bracing in any season.
- Bring a swimsuit to the waterfront and floating saunas. Korean spas have their own rules for each area.
