Bywater Sauna
Seattle, Washington
Bywater Sauna runs Minnesota-built barrel saunas that travel between Seattle beaches — Alki, Golden Gardens, Lincoln Park, and Leschi Marina — pairing wood-fired heat with direct access to Puget Sound cold plunges. Founder Nate Garberich started Bywater out of the Coldwater Collective community, and the barrel format holds 16 people comfortably so groups get a social sauna experience rather than a cramped one. Twin wood fires keep one end scorching for sauna veterans while the door end runs milder for newcomers. Drop-in sessions run $35-40 per person and memberships are available.

Frequently Asked Questions
How does Bywater Sauna work — is it a walk-in or do you come to my event?
Bywater operates a rotating schedule at Seattle beach locations — Alki, Golden Gardens, Lincoln Park, and Leschi Marina — where the barrel saunas are parked and open to the public. Guests book a session at whichever location Bywater is running that day. It's a mobile operation in the sense that the saunas travel between locations, but individual bookings happen at Bywater's parked location rather than at your address.
How much does a Bywater Sauna session cost?
A one-time drop-in pass runs $35 to $40 per person. Bywater also offers monthly memberships for regulars who plan to sauna often. Pricing includes the sauna session and access to the adjacent cold plunge — the whole point of the setup is the hot-cold contrast.
How many people fit in a Bywater sauna?
Each barrel sauna holds up to 16 people, though the round shape means it never feels crowded. Twin wood fires create a temperature gradient — the fire end runs hotter for experienced sauna-goers, the door end stays milder for beginners or anyone wanting a break from the heat.
Where is the cold plunge?
Puget Sound is the cold plunge — that's the whole point of parking at beach locations. Depending on which Bywater location you visit (Alki, Golden Gardens, Lincoln Park, or Leschi Marina) you'll step out of the sauna directly to the waterline. In winter, Sound temperatures run in the 40s Fahrenheit; summer sits in the low 50s.
Do I need to book in advance?
Yes — sessions fill up fast, especially in fall and winter which are peak sauna season in Seattle. Check Bywater's current schedule and book online for the specific location and time slot you want.
Can Bywater host private events or bring a sauna to my place?
Bywater's model is beach-location drop-in and membership rather than private event delivery to your address. If you're looking for a mobile sauna to bring to your Seattle backyard, corporate event, or wedding, request a quote through BookAShvitz and we'll match you with vendors that specifically do event delivery.
