Designed for sustained moisture, rain-season use, and urban lots
Seattle’s persistent rain and high ambient humidity place real demands on a sauna’s envelope: vapor management, material selection, and ventilation all require more care here than in dry climates. Every build is detailed for moisture resilience, with thermally modified timber chosen for its dimensional stability under long-term exposure. Urban lot constraints and Seattle’s seismic zone also inform how the structural base is configured and anchored.
