Sauna FAQs

Benefits of Sauna

What are the main benefits of using a sauna? +

People use saunas to support relaxation, stress relief, muscle recovery, improved circulation, better sleep, detoxing the body, increasing longevity and many more. Sauna has been studied and proven to be among the most efficacious practices known to man.

Is there a difference in benefits between infrared and traditional saunas? +

Infrared saunas provide radiant heat at lower temperatures, which many users find more comfortable for longer sessions. Traditional saunas heat the air to higher temperatures for a classic, intense sauna experience. Both are popular for wellness use—the best choice depends on personal preference.

How often should I use a sauna, and how long should sessions be? +

Most people use a sauna 3–5 times per week for 15–45 minutes per session. Start shorter and increase gradually, stay hydrated, and listen to your body.

Choosing the Right Sauna

Which sauna type should I choose: infrared, traditional, or hybrid? +

Infrared saunas are known for lower-temperature comfort and convenience. Traditional saunas offer higher heat and a more intense, classic feel. Hybrid saunas combine both options, allowing flexibility based on how you want to use your sauna.

What size sauna do I need? +

One- and two-person saunas are ideal for personal daily use. Larger models offer more room to stretch or share with others. If space allows, many buyers prefer to size up for added comfort.

What’s the difference between full spectrum and far infrared? +

Far infrared focuses on steady, comfortable radiant heat. Full spectrum typically includes near, mid, and far infrared wavelengths for those who want the broadest range of infrared output. Both are effective for general wellness use.

What to Know Before You Order

Will this sauna work in my home or space? +

Most saunas work well in residential spaces as long as you have adequate room, ventilation, and the proper electrical connection. Always review product dimensions and requirements before ordering.

What are the electrical requirements? +

Many smaller infrared saunas use a standard 120V outlet. Larger infrared and traditional models often require a dedicated 240V circuit. Electrical requirements are listed on each product page.

How difficult is assembly and setup? +

Most saunas are designed for straightforward assembly and can be set up in 1–3 hours with two people. Some traditional models may require an electrician if hardwiring is needed.

How much does it cost to run a sauna? +

Operating cost depends on sauna size, heater wattage, usage frequency, and local electricity rates. Most owners find sauna use comparable to running other common household appliances.

Shipping & Warranty

How is a sauna shipped and delivered? +

Saunas typically ship via freight in boxed or crated shipments. The carrier will contact you to schedule a delivery appointment once the shipment reaches your area.

Is shipping included in the price? +

Yes. All saunas include free shipping. The price shown on the product page is the final delivered price.

What warranty comes with my sauna? +
