Redwood Outdoors Thermowood Garden Sauna – Jules Walters' Outdoor Saunas selections

Product Pros

  • Heat to 195F in < 1 hr
  • Two-level seating
  • Matching plunge tub
  • Range of optional extras

Complementing the classic cabin design, the matching Alaskan plunge tub – with an option to upgrade to a dual heater and chiller – offers the whole sauna experience in your own backyard.

Redwood proposes the Fire & Ice sauna-and-plunge tub combination, for its potential health and recovery benefits; a technique used by professional athletes globally. They say the plunge tub is designed to replicate the Finnish tradition of jumping in the snow between sauna sessions.

Seneca 2-Person Barrel Sauna from Renu Therapy – Jules Walters' Outdoor Saunas selections

Renu Therapy – Seneca 2-Person Barrel Sauna

There are several high-quality details that makes this a frontrunner for a best barrel sauna badge. Eye-catching details include the outdoor seating and sleek glass door. Both add to the aesthetic and practical appeal of the standard barrel sauna, in this version marketed by Renu Therapy.

Product Pros

  • Cedar & rustic fir options
  • Sleek design and finish
  • Outdoor seating
  • Heater options
  • Durable, high density base

Product Cons

The standard 4.5kW heater and hot stones mean you can use this as a dry or steam sauna. Attractive upgrades include a remote-controlled heater and optional rear view window.

Redwood Outdoors Cedar barrel sauna for 6 occupants - from Jules Walters' outdoor saunas selection

Redwood Outdoors – Cedar Barrel Sauna (6 Person)

This imposing barrel sauna for up to 6 people in Canadian red cedar is Redwood Outdoor’s best seller.

If you relish controlling the heater remotely, from home, office, or the ski slopes, be sure to order it from the off, as the manual heater can’t be upgraded. And, for peace of mind in the wet, opt for the roof shingles too.

Product Pros

  • Heats to 195F in < 1hr
  • Cedar or thermowood
  • Remote control option

Product Cons

  • Limited reviews

Variations on this barrel sauna for up to 8 occupants, and in thermowood rather than cedar, are also available from the same supplier.

Almost Heaven Saunas Salem – 2-Person Traditional Steam Sauna in Cedar - from Jules Walters' outdoor saunas selection

Almost Heaven Saunas Salem – 2-Person Traditional Steam Sauna in Cedar

Almost Heaven Saunas, with their mountain-based factory in West Virginia, take pride in being one of the few sauna manufacturers based in the United States. They have solid corporate roots too, as they’re owned by Finland’s Harvia Group; the world’s biggest manufacturer of sauna heaters.

Product Pros

  • Plenty of good reviews
  • Fits almost any space
  • Discount prices often available
  • Easy DIY assembly (for 2 people)
  • Instructions & customer service

Product Cons

  • Outer layer’s not 100% watertight
  • Needs rain jacket

If you live in an area with a lot of rainfall, the optional rain cover is a must, as some of the customer reviews confirm. (Don’t expect the barrel sauna alone to be entirely watertight in wet weather.)

Outdoor Infrared Saunas

Kisrais Bluetooth Compatible FAR Infrared Sauna in Chinese Fir - from Jules Walters' outdoor saunas selection

KISRAIS Bluetooth Compatible FAR Infrared Sauna in Chinese Fir

This is a great option if you prefer to take your saunas alone, and if you’re short on space – and budget.

You can also get easy payment terms.

Product Pros

  • Most affordable
  • Durable wood construction
  • Warp & rot resistan

Product Cons

  • Limited warranty

The Kisrais design, in Chinese Fir, is available in the one-person version (shown here) and a slightly wider model, for two occupants sitting side by side. A valuable extra benefit is its suitability for being used indoors as well as outdoors. It’s one of the most portable cabin saunas on the market, so you can easily imagine moving it from in-to-out and back again, as the mood and season takes you!

One drawback is the limited warranty. Kisrais isn’t the only one you that asks you to pay extra for 5 years cover against defects.

Clearlight Sanctuary Outdoor Full Spectrum 2-Person Infrared Sauna

Clearlight Sanctuary Outdoor Full Spectrum 2-Person Infrared Sauna

Clearlight claim a leading edge among infrared sauna manufacturers, with their contemporary design and “groundbreaking innovation”. It does comes with a full-spectrum heating system, digital controls you can operate remotely. It is a sleek-looking cabin.

Product Pros

  • Well detailed and finished
  • Chromatherapy included
  • High praise from customers
  • Good warranty on components
  • Easy installation

Product Cons

  • Only a 5-yr warranty on cabin

Most of the finishing features, that often come as optional extras with other brands, are all-inclusive. And you can upgrade to a 5-person version of this sauna for only about 15% more on the price.

Sun Home LuminarTM Outdoor 5-Person Full-Spectrum Infrared Sauna

Sun Home Luminar™ Outdoor 5-Person Full-Spectrum Infrared Sauna

Sun Home claim this is the only outdoor infrared sauna in the world equipped with 10 full-spectrum heaters (and 5 far infrared) to keep your sessions hot all year around. It’s garnered great customer reviews, and been named best outdoor sauna in the world by Sports Illustrated and the New York Post.

Product Pros

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

Product Cons

  • Warranty limited to 6 years
  • More reviews needed

My one quibble with Sun Home: they reckon that, with an estimated operational life of 30,000 hours, the infrared heaters should last for over 100 years with daily use. Given that, I think they could reasonably offer a longer warranty than 6 years!

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, UV rays, and stormy weather. 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. As well as shape and dimensions, 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. Remember to include the cost of any must-have extras.You’ll also need to consider annual running costs; including routine maintenance and operating expenses.

Reviews and recommendations

Finally, 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.

How long will an outdoor sauna last – and what can I do about mold growth?

Experience and typical warranties suggest the average lifespan of a quality outdoor sauna is 15 to 25 years. Actual lifespans vary widely, dependent partly on design but more so on location and how well they are maintained.

Excessive mold on the inside panelling is one of the most disagreeable and unhealthy developments in outdoor saunas. But bear in mind that mold growth is a natural occurrence, particularly in hot and humid climates. So, always allow the inside of your sauna the opportunity to dry out naturally with the door open when not in use.

A monthly maintenance routine, while the sauna is in use, should include wiping down of all internal surfaces with a mild (non-bleach) mold remover product. You can also scrub off mold with a paste made from baking soda and water. For more stubborn mold stains on wood, you can always resort to light sanding.

What’s the most striking clinically-proven health benefit of saunas?

One study conducted by researchers from the University of Eastern Finland and the University of Jyväskylä has shown that frequent sauna bathing can lower the risk of death from cardiovascular disease (CVD) in middle-aged and elderly people.

The research found the mortality rate from cardiovascular disease (CVD) among people taking a sauna four to seven times a week was 73 percent lower than those using a sauna just once a week.

Tell me a few things not everyone knows about outdoor saunas?

Outdoor saunas are nothing new. It’s believed, with some evidence, that they’ve been around for at least two thousand years in one form or another. The earliest ones were dug into embankments, before evolving into log cabins above ground.

Smoke from burning embers was a key feature of early saunas, and the word sauna itself is believed to derive from the Finnish word savuna, meaning “in smoke”.

One of the first written descriptions of the Finnish Sauna came from the hand of Nestor the Chronicler early in the 12th Century.

Saunas are deeply enmeshed in Finnish practice and culture. Historically, they were places both to give birth and to lay out the dead. And you will still find people in Finland today who were born in a sauna.

The first saunas in America were built by Finns who arrived in 1638, and settled in the area that’s now the State of Delaware.
