Complete Guide to Choosing Your Perfect Home Sauna
Investing in a home sauna is a significant decision that can transform your wellness routine for years to come. This comprehensive guide will help you choose the right sauna type, size, and features for your needs.
Types of Saunas
Traditional Finnish Saunas
Traditional saunas use electric or wood-burning heaters to heat the air to 150–195°F, creating the classic sauna experience with optional steam from water poured over hot stones.
- Best for: Authentic sauna experience, high heat tolerance
- Heat source: Electric or wood-burning heaters
- Temperature: 150–195°F
- Installation: Requires proper ventilation and electrical/chimney setup
Infrared Saunas
Infrared saunas use infrared light to heat your body directly rather than heating the air, operating at lower temperatures (120–140°F) with direct infrared heating.
- Best for: Lower temperature preference, direct infrared heat
- Heat source: Infrared panels (near, mid, far-infrared)
- Temperature: 120–140°F
- Installation: Plug-and-play, minimal installation required
Barrel Saunas
Outdoor barrel-shaped saunas combine traditional heating with space-efficient design and aesthetic appeal.
- Best for: Outdoor installation, space efficiency, visual appeal
- Heat source: Electric or wood-burning
- Capacity: 2–8 people
- Installation: Outdoor placement, level surface required
Choosing the Right Size
1–2 Person Saunas: 3' x 4' to 4' x 4' interior
2–3 Person Saunas: 4' x 5' to 5' x 5' interior
4–6 Person Saunas: 5' x 7' to 6' x 8' interior
6+ Person Saunas: 8' x 10' or larger
