The 26 outdoor sauna designs combine relaxation, distinctive design, and a connection to nature in backyard settings.
In 2025, outdoor saunas include charred-timber structures tucked into snowy forests, glass-walled sanctuaries with firelight, and cedar-scented cubes set among trees.
These 26 designs feature moody minimalism, natural materials, and the atmosphere of a remote retreat.
