Outdoor saunas can be the perfect retreat, particularly if you can have one in the privacy of your own yard.

  • Panoramic dura-glass windows
  • 15 heaters cover all angles
  • Medical grade chromotherapy
  • Surround sound

Outdoor Saunas – Things to Consider Before You Buy

Here are a few things to keep in mind when choosing the best outdoor sauna for you.

Size and Space

Look at what space you have to house an outdoor sauna and select one that fits comfortably within the space. Consider the dimensions & shape, including the height, to get the best use of space. And decide at the outset what type of sauna you want; and whether an outdoor sauna is best for you, or an indoor sauna for your home.

Materials and Durability

Look for saunas made from high-quality materials that can withstand outdoor elements, like rain, snow, and UV rays. Cedar is a popular choice, as it’s one of the most resistant woods to rot, decay, and insect damage.

The barrel sauna is popular too with a shape and construction well suited to the rigors of the changing seasons; particularly to the fall and winter challenges of rain, hail and snowfall.

Few outdoor models, though, are 100% waterproof without an additional protective layer over the wood panelling. This is often obtained though an upgrade or optional extra; typically a removable rain cover, or an additional felt or shingle layer applied to the roof.

Heating System

Decide which heating system is right for you. Traditional saunas typically use a wood-burning stove, while an electric heater is more common in modern saunas.

So, consider the heating capabilities, energy efficiency, and ease of use of each option.


Consider the overall design and aesthetics of the sauna to ensure it complements your backyard and style preferences. That could include sauna features such as door style, window options and exterior finishes.

Warranty and Support

Bear in mind the warranty offered by the manufacturer or reseller.

You will see from the saunas I have chosen here that the length and scope of warranties, particularly on the heaters and the sauna cabins, does vary.


Decide on your comfortable budget range at the outset, and compare saunas within that range. You will need to consider running costs too, including maintenance and operating expenses.

Reviews and Recommendations

Take a moment to read the reviews from customers who have already bought the saunas you’re considering. I have done that for you for the saunas listed here; but you could also ask friends and family what they think, or talk to the manufacturers, before deciding on the best outdoor sauna for you.

Frequently Asked Questions

Do you need a permit for an outdoor sauna?

Regulations on outdoor saunas for the home vary, depending on your state, county or city.

For peace of mind, you can always check with your local building or zoning department. Usually, though, structures of up to 120 square feet don’t require permits in the United States; and that’s ample space for the saunas I’ve chosen here.

But, beware of issues with your neighbor if you place your sauna right up against the property line or a shared access route!

How much does an outdoor sauna cost?

Prices range widely, so this comes largely down to taste – and how much you want to spend.

The most popular, prefabricated options for home assembly range from around US $2,000 to $12,000. A bespoke outdoor sauna built entirely to your specifications, and with no DIY assembly, will inevitably cost more.

Are outdoor saunas expensive to run?

The cost of running an outdoor sauna varies depending on several factors, such as its size, adequacy of of insulation, type of heating system (electric, gas or wood), local utility rates, and how often you use it.

As of 2023, costs of running a 6ft-by-4ft outdoor sauna with a 6kW heater would typically be anywhere in the region of $20 to $50 a month in the United States, or around $240 to $600 a year. Bear in mind that utility rates vary widely from area to another, and that keeping your sauna at the perfect temperature in winter months will cost more.

If you want to calculate this more accurately: for an electric outdoor sauna, multiply your heater’s wattage (in kilowatts) by the number of days a year you expect to use the sauna, by the average length of your sauna sessions, by your current price per kilowatt hour of electricity.

For example: 6kW x 260 days (ie: 5 days p/w) x 1-hour sessions x 15 cents per kW-hr = $234 p/a.

Do outdoor saunas need insulation?

If you’re choosing a prefabricated model for outdoors, the answer is generally no, it won’t need additional insulation, as the natural stresses of outdoor use will have been allowed for in its design and manufacture.

Barrel saunas, for example, are designed to retain their heat without insulation; principally through the circular barrel shape and close fitting planks.

Do outdoor saunas add value to your home?

Yes. A well installed, high-quality outdoor sauna will increase your property value, if you maintain it well and you’re happy to leave it behind when you sell.

Not every buyer will value your outdoor sauna the same but, for people with busy lifestyles, the relaxation and health benefits it offers will definitely make your home stand out. If it’s well designed and integrated into the environment, an outdoor sauna will also add to your home’s curb appeal, and the overall aesthetic appeal of the property.

Can you use an outdoor sauna in the winter?

Yes! You can certainly use an outdoor sauna in the winter. In fact, many people enjoy using saunas during winter months for a cold weather experience that can both relax and invigorate.

Can you build your own outdoor sauna?

Absolutely. You only need to be moderately good at DIY to build your own outdoor sauna. You may need to hire professionals, though, if you need a concrete slab laid for the sauna to stand on, or to wire in a heater.

If you’re on a tight budget, or you’re just happy to take on the DIY challenge, the rest of the build is relatively easy; and easier still if you buy your outdoor sauna as a prefabricated kit for home assembly, like most of the ones I’ve listed here.

Why are outdoor saunas typically made of wood?

Saunas are made of wood for a few reasons, including its aesthetic appeal as a beautiful, natural product. Perhaps the biggest consideration, though, is the durability of particular types of wood, and their resistance both to moisture and heat.
