Can You Place an Infrared Sauna Outside?
Most home infrared saunas are built for indoors. If you want to place your FIR sauna outside, you have to make sure it is specially designed as an outdoor sauna room.
This is because exposing the sauna elements to humidity, heat, snow, and wind can ruin them, and if the sauna is not well insulated, it will be harder to keep the heat inside.
An outdoor infrared sauna has to be built with water-proof solid wood, it has to be well insulated, and usually comes with a roof.

How to Choose an Outdoor Infrared Sauna
Outdoor far infrared saunas are different than indoor ones and are usually more expensive (see the best 2 person indoor infrared saunas or the best 3-4 person infrared saunas)
But still, they make a wise long-term choice and will help you detoxify, boost your immune system, relieve chronic pain, lose weight (not just water weight!), and much more.

Here are the most important factors to consider:
1. Electricity – an outdoor far infrared sauna needs electricity to function. You’ll need to install it next to an adequate outlet. Make sure it is close enough to a GFI outlet with enough capacity.
(You’ll find the power requirements for each sauna we recommend – in our reviews below)
2. Space – The best thing about an outdoor infrared light sauna is the fact it won’t take up space inside your home. You can place it on your patio, in your backyard, or on a deck outside.
And, if you have enough space outdoors, you can enjoy a large sauna – fit for 4-5 people.
3. Insulation – to be able to work up a sweat you’ll need a far infrared technology sauna that keeps the heat inside even when the weather is cold.
A specially designed outdoor sauna is made with the right kind of solid wood (more on that below) and is well-insulated. This will also lower your electricity spend on the sauna.
4. EMF radiation – choosing a low EMF infrared sauna is critical for your safety.
A safe level of EMF is considered to be anything below 3.0mG.
5. The number of infrared heaters – since outdoor IR saunas are typically larger (3-person or more) – the number of heaters can be between 6-10.
A sauna for 4 people requires 8-10 heaters, while a 3-person sauna will have 6-8.
The number of heaters can make a difference when it comes down to the temperature control and the heat inside.
6. Best wood type for outdoor saunas – the commonly used ones are hemlock, cedar, pine, and spruce.
Cedar is considered the best, followed by hemlock.
The cheaper ones are made with pine or spruce. Cedar and hemlock are the most stain and moisture-resistant.
7. Safety – make sure it is up to local building codes, safe, and able to withstand weather damage.

The SunRay Saunas Grandby FIR rectangle outdoor sauna has a pitched, waterproof roof and comes with a rain cover, making it safe to assemble and use outside – even when it rains.
It comfortably accommodates 3 people, has 8 ceramic heaters (which heat up faster in colder weather), and reaches up to 140 F, inside a solid Canadian Hemlock build.
The natural Canadian hemlock is mildew, rot, rust, and corrosion resistant, and blends beautifully with nature outside your home.
This sauna also comes with an oxygen ionizer, which releases negatively charged ions into the air, which attach to positively charged particles such as dust, bacteria, and other pollutants.
This process neutralizes the particles and makes them too heavy to remain in the air, causing them to fall to the ground. This helps to improve the air quality inside the sauna and provides a more comfortable and healthy experience for the users.

- Accommodates 3 people comfortably
- Fits taller people

Indoor vs. Outdoor Infrared Sauna
An indoor FIR sauna takes up space inside your home, while an outdoor sauna doesn’t.
Indoor saunas use a power supply already in your home, while outdoor ones require weather-resistant cables and an adequate outlet.
Outdoor saunas are usually larger and can accommodate more people, while indoor saunas are more private.
An outdoor sauna must have a roof and be built with humidity-resistant wood, while indoor saunas may last longer because they won’t be affected by temperature changes.
Finally, outdoor saunas require more power and may heat up slowly compared with indoor saunas.
How Much Does an Outdoor Infrared Sauna Cost?
DIY outdoor infrared sauna kits, that include all the necessary materials and instructions to build your outdoor infrared sauna typically cost between $2,000 and $10,000.
The cost to buy and build an outdoor infrared sauna will vary depending on the size, quality of construction, wood type, heater type, and energy rating.
Size is usually the biggest factor in determining the price.
The larger the sauna, the higher the purchase price.
How Much Does it Cost to Run an Outdoor Infrared Sauna?
Infrared saunas use less electricity than traditional saunas.
They use less power because they mostly heat surfaces and not the surrounding air.
They also have a lower preparation time – most FIR saunas heat in up to 30 minutes, while traditional saunas take an hour or more to heat up to the “sweating temperature”.
The electricity cost for an FIR sauna depends on how much you pay per kilowatt-hour on your current plan.
For example, a 2200W FIR sauna, running for one hour, will generally use 1KWh of electricity – around 26.4 cents in the USA.
What is the Best Wood for an Infrared Sauna?
According to sauna experts, Cedar has always been the most popular choice for an infrared sauna, because it is naturally resistant to moisture and will not contract or expand as other wood when the temperature changes.
It is also one of the most durable woods. However, it can vary in quality and health certifications.
How Often Should You Use an Outdoor Sauna?
.
In the beginning, use it at least twice a week, starting with 10-15 minutes at a time and working up to 30-40 minutes at a time slowly.
As you get used to using an infrared sauna, you will need to get used to how long it takes to break a sweat and time yourself after that point
To your health and happiness,
