Bywater Sauna is one of the world’s largest mobile barrel saunas. This lets us move around and set up shop beachside, so you can join the community at either Golden Gardens Park or Alki Beach Park. Check out our schedule.
Saunas have existed for thousands of years, and cold water has existed for, well, a lot longer. Spending time in both are linked to well-documented health benefits.
But saunas aren’t only tools for good health. Throughout human history, saunas have served as meeting points — places to cultivate and enjoy friendship and connection.
That’s why, with Bywater, we’re getting back to the basics: Come for the hot and cold. Stay for the friends.
Find our mobile sauna at Golden Gardens Park and Alki Beach Park, depending on the day.
Times: Most Monday, Wednesday, and Friday mornings. Occasional Saturday mornings
Location: North of the Golden Gardens Bathhouse.
Parking: Golden Gardens has three parking lots. It can get busy during peak hours, so if you’re having trouble, park along Seaview Ave. to the south of the park.

Things to know before you go.
Yes! Each of our locations have public restrooms, but you can save time by arriving in your bathing suit.
Yes! You can rent a towel for $5 per session. Having a towel to sit on is important when enjoying the sauna.
We have limited areas for storage, so we recommend leaving all non-essential belongings in a car, if you can.
If you’re new to sauna, stay in for 5-10 minutes at a time to let your body adjust, and then slowly increase your duration from there. No matter your experience level, we recommend you stay in for no more than 15-20 minutes. If ever you feel dizzy or lightheaded, hop out!
First thing’s first: It’s not a competition. You can get health benefits from spending as little as 1-3 minutes in the water, and plunging for too long can increase risk without increasing benefits. If it’s your first time doing a cold water plunge, try to stay in for 1-2 minutes. If you start to shiver at any time after one minute in the water, it’s time to get out.
