Indoor Saunas: Traditional vs. Infrared

Traditional Saunas use heated stones or electric heaters to warm the air — creating a hot, humid atmosphere (150°F to 190°F). Water can be poured onto the rocks for steam.

Infrared Saunas use near, mid, or far infrared light to heat your body directly at lower temperatures (110°F to 140°F) without steam.

Key Considerations for Indoor Saunas

• Electrical Setup: Most infrared saunas plug into 120V. Traditional models may require 240V wiring.

• Space Requirements: Check sauna footprint + ceiling height.

• Ventilation: Traditional saunas need ventilation for steam. Infrared less so.

• Noise & Design: Infrared saunas often quieter and sleeker.

• Maintenance: Steam saunas may require mold prevention.
