Sauna FAQs

General Questions
What’s the difference between an infrared sauna, a traditional sauna, and a hybrid sauna? +
Infrared saunas: Heat your body directly with infrared light for deep tissue penetration. Lower temperatures (120–150°F) make it easier to stay in longer. Known for relaxation, recovery, and potential wellness benefits.

Traditional saunas: Heat the air with electric heaters or wood-burning stoves. Higher temperatures (160–195°F) provide an intense, sweat-heavy experience, boosting circulation and overall wellness. Zero EMF output.

Hybrid saunas: Offer the benefits of both. They use infrared waves for deeper tissue penetration alongside much higher heats from a traditional sauna stove.
How do I choose the right sauna for me? +
Consider:
Person Capacity: How many people will use the sauna? A larger capacity sauna provides more space but takes up more room.
Indoor vs. Outdoor Use: Indoor saunas cannot be safely used outdoors. Choose the right option for your space.
Heating Style: Infrared, Traditional, or Hybrid.
Full Spectrum vs. Standard Infrared: Full Spectrum saunas provide near, mid, and far infrared. This is a desirable but generally more expensive feature.
EMF Levels: Low (<6–10 MG), Ultra Low (<3–5 MG), or Near Zero (<2 MG). Lower EMF is generally better, but more expensive.
What size saunas do you offer? +
We carry 1-person, 2-person, and up to 6-person+ models. Consider both interior comfort and available space when selecting a size.
Shipping & Delivery
How is my sauna shipped? +

Installation & Setup
Do saunas require professional installation? +
Infrared saunas: No, most models are plug-and-play and can be assembled in 1-2 hours.
Traditional saunas: Most are simple to set up but may require hardwiring by a licensed electrician.
What are the electrical requirements? +
1-2 person infrared saunas: Standard 120V outlet (some exclusions apply—check product details).
Larger infrared saunas & traditional saunas: Many will require a dedicated 240V wiring (professional installation highly recommended).
How long does it take to assemble a sauna? +
Most saunas take 30 minutes to 3 hours with two people and come with easy-to-follow instructions.
Usage & Maintenance
How long does it take to heat up? +
Infrared saunas: 10-15 minutes on average but depends on the model and number of heaters.
Traditional saunas: 30-45 minutes on average but depends on the model and number of heaters.
How do I clean my sauna? +
Wipe down with a damp cloth after each use.
For deep cleaning, use a vinegar-water mix—avoid harsh chemicals.
Specialty wood cleaner and treatment is advisable.
What type of wood is best for a sauna? +
Canadian Hemlock: Durable, affordable, and commonly used in infrared saunas.
Red Cedar: Premium, naturally rot-resistant, aromatic, and highly durable.
Basswood, Mahogany, and Fir: Alternative high-quality woods with varying aesthetics and insulation properties.
