FAQ

Can I finance my sauna purchase?

Yes! We offer easy monthly payments through our financing partners so you can enjoy your sauna today without paying in full upfront.

Do I need professional installation?

Most saunas are designed for easy assembly in under 2 hours with basic tools. No electrician needed for 120V models.

What’s the warranty and return policy?

All saunas include a manufacturer’s warranty (1–5 years depending on brand) and Martin Sauna’s 30-day satisfaction guarantee.

Infrared vs. Traditional Saunas – What’s the Difference?

Infrared saunas use panels that emit infrared light to gently heat your body directly at a lower ambient temperature (100–150°F). This makes the experience more comfortable for longer sessions while still delivering deep muscle and joint relief.

Traditional saunas heat the air using stones and water, creating a hotter environment (170–200°F) with steam if desired. They deliver the classic sauna “sweat lodge” feel and a more intense heat experience.

Both styles support detoxification, stress relief, and cardiovascular health — the best choice depends on whether you prefer a gentle, longer sweat (infrared) or a high-heat, traditional experience.

What are the health benefits of regular sauna use?

Research, particularly from long-term Finnish studies, shows that regular sauna sessions (3–4 times per week) can significantly reduce health risks. Frequent sauna use has been linked to a 50% lower risk of fatal cardiovascular events and up to a 66% lower risk of dementia and Alzheimer’s disease. Heat exposure improves circulation, lowers blood pressure, and supports recovery by reducing inflammation markers. Sweating also aids detoxification, while many users report improved sleep quality, reduced stress, and overall enhanced well-being.
