- Hemlock: Smooth texture, minimal resin, excellent heat retention

Installation Considerations
Foundation Requirements
A proper foundation ensures your outdoor sauna remains level, stable, and protected from moisture. Most outdoor saunas require a concrete pad, gravel base, or treated lumber platform.
Foundation Options
- Concrete Slab: Most permanent and stable, ideal for heavy barrel saunas
- Gravel Base: Cost-effective drainage solution for smaller saunas
- Deck Platform: Elevated option that improves drainage and access
- Paver System: Modular solution that's easy to level and adjust
Electrical and Plumbing
Electric outdoor saunas typically require 220V service and professional electrical installation. Consider future needs for lighting, ventilation fans, and sound systems during the planning phase.
Permits and Regulations
Check local building codes and HOA regulations before installation. Many areas classify outdoor saunas as accessory structures requiring permits, especially for permanent installations or electrical connections.
