FAQ's

Answers to the most common questions

What makes you different from all of the other sites I have visited?

First and foremost, Therasauna is made in the USA. To our knowledge, there are only 3 manufacturers in the USA. We are 1 of them. Our competitors do a great job of slapping their name on lesser quality imports from Asia and charging premium prices. If you have issues with your unit, good luck. We are HERE. Sales, service and customer support. All here.

MandeSpa, made in Europe with the finest wood. We import them and have them readily available HERE in the USA. They ship from our warehouse in Wisconsin. Sales, service and customer support. All here. Ask our competitors where their saunas are made.

It's great piece of mind knowing we are here and accessible.

I have seen saunas that are less expensive on other sites. Why?

These saunas are of lesser quality. If you want our advice, just go to Alibaba.com and buy one directly from there. Very same units as you see on our competitors' sites for a fraction of the cost. We sell premium brand name saunas that are crafted individually. These are not "cookie cutter" units produced in mass overseas.

What are the health benefits and safety considerations of saunas?

Using a sauna regularly offers many proven infrared sauna benefits including detoxification, improved blood circulation, muscle recovery, stress relief, skin rejuvenation, and better sleep. Traditional steam saunas may also help with respiratory health and relaxation. Please note that sauna use may not be recommended for people with certain medical conditions (such as heart issues, high blood pressure, or pregnancy). Always check with your healthcare provider before starting a sauna routine.

What are the electrical and installation requirements for your saunas?

Most smaller saunas use a standard household outlet, but larger saunas may require a dedicated 20-amp or 240V circuit. Installation is simple thanks to pre-assembled panels and easy instructions. While many customers complete installation themselves, we recommend a licensed electrician for electrical connections to ensure safe sauna setup.

PLEASE NOTE THAT YOUR UNIT MUST BE ETL CERTIFIED TO BE SOLD IN THE USA. MANY OF OUR COMPETITORS DO NOT MEET THIS STANDARD. PLEASE CHECK BEFORE MAKING THE PURCHASE!

How long does sauna delivery and setup take?

TheraSauna orders typically ship within 1 business week, and transit time varies by location. Mande Sap orders typically ship within 1 business week. Once your sauna arrives, most models can be assembled in 1–2 hours by two people. Larger outdoor saunas may take slightly longer. We’ll send you regular shipping updates so you know exactly when to expect your sauna curbside delivery. WE STRONGLY SUGGEST ASKING ABOUT AVAILABILITY BEFORE PURCHASE.



Do you offer sauna financing or payment plans?

Yes, we offer flexible sauna financing options at checkout. Choose from monthly installment plans from Shop Pay, including 0% APR promotions on approved credit. This makes it easy to enjoy the benefits of a sauna at home without paying all at once.

How do I clean and maintain my home sauna?

Home sauna maintenance is simple:

  • Wipe down benches and walls with a gentle, non-toxic cleaner.
  • Use towels to keep wood surfaces clean and dry.
  • Inspect heating elements periodically for dust.
  • Replace light bulbs or minor components as needed.

With proper care, your sauna will remain in excellent condition for many years.

Do you provide customer support after purchase?

Yes! Our sauna support team is here to help with installation questions, troubleshooting, and ordering replacement parts. We also offer step-by-step guides and video tutorials for setup and maintenance. You can reach us via phone, email, or chat anytime.

How often should I use my sauna, and how long should each session last?

Many wellness experts recommend using a sauna 4–7 times per week, though some people enjoy it daily. Typical infrared sauna sessions last 20–40 minutes depending on comfort level and heat intensity. Always stay hydrated, start with shorter sessions if you’re new, and exit if you feel lightheaded. This routine ensures maximum sauna health benefits while keeping you safe.

What’s the difference between infrared and traditional saunas?

The main difference is how heat is produced and absorbed:

  • Infrared saunas use infrared light to directly heat your body, which allows for lower air temperatures (110–150°F) and deep tissue penetration. Many people find them more comfortable and easier to tolerate.
  • Traditional steam saunas heat the air to higher temperatures (160–200°F), creating a more intense environment that some prefer for relaxation and sweating.

Both types provide excellent wellness benefits, and your choice depends on comfort, health goals, and personal preference.
