Private saunas in Seattle, United States
Elsewhere Sauna at Magnuson Park
Elsewhere Sauna runs shared wood-fired mobile sauna sessions at Magnuson Park in northeast Seattle, with private rental options as well. The operator rotates between Seattle waterfront sites and Snoqualmie, so Magnuson Park is a location to check in the live booking calendar, not a permanent daily setup. Bring swimwear, a towel and water; the exact meeting point comes with your reservation.
