Quick answer
Focus on heater type, wood quality, size, and weatherproofing. A traditional sauna with a separate heater offers authentic steam and dry heat, while an all-in-one unit simplifies installation.
Heater type: electric vs. wood-burning
Electric heaters are convenient, require less maintenance, and can be controlled with a timer or thermostat. Wood-burning heaters offer a traditional experience but need a chimney and more space. Choose based on your access to electricity and desire for authenticity.
Wood quality and insulation
Cedar is naturally resistant to moisture and insects, making it a top choice for outdoor saunas. Tongue-and-groove construction improves insulation and durability. Thicker walls retain heat better but add weight and cost.
Size and capacity
Measure your available space and consider how many people will use the sauna at once. A 2-person sauna fits a small patio, while a 4-person model requires more room but offers L-shaped benches for comfort. Also consider clearance for the heater and door swing.
Decision rules for choosing an outdoor sauna
- Heater type: If you want precise temperature control and low maintenance, choose an electric heater. If you prefer a traditional experience and have ventilation, choose wood-burning. Electric heaters are more common in modern outdoor saunas.
- Wood type: Cedar is the standard for outdoor saunas due to its natural resistance to rot and insects. Hemlock or pine are cheaper but may require more maintenance. Cedar offers the best balance of durability and aroma.
- Weatherproofing: Look for a steel or shingled roof, tempered glass windows, and a door that seals tightly. These features keep the heat in and the weather out. A well-sealed sauna will heat faster and last longer outdoors.
- Size and layout: Measure your patio or yard and consider bench layout. L-shaped benches allow more people to sit comfortably in a compact footprint. A 2-4 person sauna fits most backyards.
