What's included - do I need to buy the heater separately?

No. Outdoor saunas comec with the PrairieFire™ 9kW electric heater, sauna stones, exterior smart control panel, 8mm tempered glass door, dimmable LED light, aluminum bucket, bamboo ladle, cedar thermometer, 2 robe hooks, HDPE support cradles, cement and ground anchors, and all assembly hardware.

What electrical setup is required before installation?

Outdoor saunas require a dedicated 240V/50A hardwired circuit installed by a licensed electrician before the sauna can be used. Outdoor saunas must be hardwired; while indoor models (e.g. Rylan) may use GFCI outlets, GFCI is not recommended outdoors due to moisture. A GFCI breaker is typically required. We recommend consulting a licensed electrician early in your planning process.

Does the sauna require a foundation or deck? Can I place it on gravel or concrete?

Yes, our outdoor models can either be anchored to a concrete pad or staked to the ground. Anchors for both concrete and ground stakes, as well as HDPE support cradles, are included in each outdoor sauna kit. Ensure any chosen surface is firm and level and can support the weight of the sauna and it's users (+1000 lbs.). If planning to place your sauna on a deck please purchase the correct anchor hardware from your local hardware store and reach out to a local contractor or structural engineer to evaluate your plans to ensure it meets International Residential Code (IRC) requirements as well as local codes specific to your area.

How hard is assembly and how long does it take?

Indoor saunas are panel-based and easy to assemble. Outdoor saunas require more effort but are still manageable. Components are pre-cut and pre-drilled, and the BILT® app provides free interactive 3D assembly instructions.

What are the shipping and delivery details?

Orders of in-stock units ship from our warehouse within 1-3 days of ordering and arrive within 7-17 days from placed order date. Please review your order confirmation and order tracking emails for additional details.

How long does it take to heat up and what is the maximum temperature?

Outdoor saunas with a 9kW heater reach 170–185°F in about 20–30 minutes under mild conditions, while indoor saunas heat up faster. Outdoor saunas can reach a maximum temperature of up to 194°F, and indoor infrared saunas have a max temperature of 150°F. Note: The 9kW PrairieFire™ heater is rated for up to 462 cubic feet and reaches 194°F.

What's the difference between the 2-4 person and the 4-6 person models?

The 2–4 person model has interior dimensions of 73.6"W × 57.6"D × 73.6"H with two 57" benches. The 4–6 person model is larger. Both use the same PrairieFire™ 9kW heater.

Can I use this as a steam sauna (wet sauna)?

Yes. Outdoor saunas are rated for both wet and dry (traditional) use. Pour water over the included sauna stones to create steam.

Can this be used in Winter/cold climates?

Outdoor saunas are designed for year-round outdoor use. Cedar naturally resists moisture and temperature changes, and the 29-gauge galvanized steel roof is weather-sealed. For colder climates (e.g. below zero Fahrenheit), we recommend preheating the sauna a little less than 1 hour ahead of time then restarting it before going in.

What app controls the sauna? Can it run the lights?

The Tuya Smart app lets you control temperature, schedule sessions, and more—all from your smartphone. At this time, the app will not control the LED lights. The LED lights are on their own 120V connection (separate from the 240V connection required for the heater) and come with a remote for operation.

Is there an interior control panel or timer inside the sauna?

For outdoor saunas, the smart control panel is located on the exterior of the sauna, which displays the timer and allows remote access via Wi-Fi app. Indoor saunas display the countdown timer both inside and outside, as the smart control panel is accessible from both inside and outside the unit.

What is the warranty and how do I make a claim?

Outdoor saunas are covered by a 5-year comprehensive warranty covering every part and component. If you believe you have a warranty claim, please reach out to us via our Support page.

Do the saunas need to be stained, sealed, or painted?

Outdoor saunas should have the exterior only stained and sealed. If you choose to paint the exterior, you MUST use a water-based product (like a water-based stain) that breathes, handles heat, and resists UV and weather. Water-based acrylics run the risk of blistering/bubbling as heat and moisture are pushed out. Do not use oil-based or moisture-trapping paints (oil-based stains, polyurethane, shellac, marine spar varnish, elastomeric coatings, glossy film-forming sealers) as these will trap moisture, cause rot, increase mold risk, and trap vapor/fumes.

What is the energy use and average cost to run the heater?

Energy use depends on how often the sauna is used and how long the heater runs at full power vs. cycling to maintain heat. Electricity cost per hour = Power (9kW) x Electricity rate ($/kWh). At the US average rate of $0.13/kWh x 9 = $1.17 per hour. For example, 30 minutes to heat up + 30 minutes to use = 1 hour (9kWh) per session. If used 2-3 times per week, expect 70-110kWh per month. In real-world usage, the heater will not run continuously for the full hour, as it cycles to maintain the set temperature.

Can outdoor saunas be used indoors (and vice versa)?

Outdoor saunas indoors: Yes! You can install an outdoor sauna indoors if the space is properly prepared for heat and humidity. Use mold-resistant drywall, vapor-barrier paint, waterproof flooring, and ensure ventilation with an exhaust fan and fresh air supply. Indoor saunas outdoors: No! It is not recommended to place an indoor sauna outdoors, even under a covered deck or patio. The indoor sauna design has electrical components on the roof and is not water-resistant. Moisture or high humidity could ruin it.

Can I pour essential oils on the heater rocks?

Yes, but oils must be diluted with water and tested in small amounts first.

Where are the saunas and heaters made?

Saunas are designed in Kansas and manufactured in Vietnam or China under strict quality control. The PrairieFire™ heaters are custom-designed and engineered in Kansas and manufactured to our specifications by trusted partners in China, with all performance criteria, materials, safety systems, and quality controls validated by our US Engineers.

Can I use red light therapy without turning on the sauna?

Yes! The red light therapy feature works independently of the heaters.

Is financing available?

Yes, financing is available for qualified buyers through Shop Pay Installments, with 3 month and 12 month payment plans and rates ranging from 0-36% APR. Shop Pay Installments can be found in the payments section at checkout. Payment options and rates are subject to eligibility and credit check by Shop Pay's lending partners.

Can I use HSA/FSA funds to purchase?

Ourdoor saunas may be eligible for HSA/FSA purchase for qualifying customers. See our HSA/FSA eligibility page for details. Consult your plan administrator and physician.

Is the sauna ETL Certified?

Yes. Our outdoor saunas are ETL Certified for residential outdoor use.

Are there any VOCs or off-gassing concerns on the assembled sauna?

Our saunas are designed with these concerns in mind. There are no VOC concerns because no chemicals, stains, or glues are used inside the sauna. For Infrared models, only the exterior is stained.

How is the sauna insulated and does it have an R-value?

Yes, the estimated R-value is between 1.4 and 1.8. Indoor Infrared Saunas are insulated by air and solid kiln-dried cedar. Outdoor Saunas are insulated by 30mm solid kiln-dried cedar. No synthetic, manmade insulation materials are used in either.

Can I order the sauna without a heater or use a wood-burning stove?

No. Saunas come as shown with electric heaters. Using a wood stove is not recommended and is outside of the design specifications. Use of a 3rd-party heater or wood-burning stove will void the manufacturer's warranty.
