OUTDOOR SAUNA BUYER’S GUIDE
Choosing the best outdoor sauna for your home can be a daunting process. Buying an outdoor sauna can become a time-consuming process, with a seemingly endless range of saunas to choose from and an overload of information and product descriptions.
To help you navigate the outdoor sauna world we’ve created a buyer’s guide. This guide will help you focus on your needs and allow you to easily find the ideal outdoor sauna for your home. Here’s what you need to know, see below.
TYPES OF OUTDOOR SAUNA
What are the different types of outdoor sauna? The four main types of outdoor sauna are – traditional sauna, infrared sauna, steam sauna, and hybrid sauna. Each of these can be further broken down based on its design and shape.
Outdoor saunas come in all shapes and sizes and can be built as cabin saunas, barrell saunas, thermowood saunas, cube saunas, panorama saunas, corner saunas, oval saunas, and pod saunas. For a full breakdown see Types of Outdoor Sauna – Complete Guide.
SAUNA SIZE
What size sauna are you looking for? You can get outdoor saunas in a wide range of sizes, from single-person capacity right up to super-seized eight-person saunas. However, the most common outdoor sauna sizes are 2, 3, and 4-person capacity.
Two-person saunas are ideal for one or two people. If you intend on using the sauna on your own – we recommend going for a 2-person device for a little extra comfort and room. Then if a friend or family member wished to join you – they can jump right in.
Three and four-person outdoor saunas are great if you want to get additional family members or a group of friends in there. Sauna comes with a wide range of health and relaxation benefits. But the social interaction and enjoyment of a shared experience are often overlooked.
SPACE REQUIREMENT
Whatever size sauna to choose to go for – you need to ensure you have available outdoor space to accommodate the device. It’s time to get the tape measure out. You’ll need to carefully measure the dimensions of the space you plan to use to house the sauna.
Then, compare the available space against the dimensions of the sauna you have in mind. Do you have enough outdoor space? Below is a table comparing the most common outdoor sauna sizes for a general overview.
BUDGET
What’s your budget? As with any significant home goods investment you’ll need to consider your budget and the prices of saunas available in your category. There are two expenses to consider when shopping for an outdoor sauna – the price of the sauna and the installation costs.
The price of the sauna should be clearly advertised by the retailer. Make sure the price includes the sauna heater and not just the cabin. As for installation costs, you’ll need to ask some questions.
Reach out to the manufacturer and establish what installation will need to be completed. Then get a quote from a qualified tradesman for the installation works.
MATERIAL OF CONSTRUCTION
Pay particular attention to the materials of construction. The best outdoor saunas are made from red cedar wood, Nordic spruce, Canadian hemlock, and basswood. You should prioritize quality over price when assessing the materials used.
Aim for a sauna that’s built to last and will stand the test of time outside in your garden or backyard. You should also pay particular attention to the type of heater.
This is the single most important piece of equipment in your sauna. Do some research, read the reviews, and make sure you are investing in a quality piece of equipment.
CLIMATE
Where do you live? You need to consider your local climate when buying an outdoor sauna. If you live in an area that experiences harsh weather conditions and significant swings in seasonal conditions – you’ll need to prioritize sourcing a sauna that will stand the test of time in these conditions.
Also, if your region experiences very cold winters you should aim for a traditional outdoor sauna over an infrared sauna. Traditional saunas operate at much higher temperatures and will feel more comfortable on a frosty winter’s evening.
ASSEMBLY & INSTALLATION
What are the installation requirements? Most outdoor saunas require self-assembly. This means they’ll be shipped to you on a pallet and you’ll have to assemble the sauna on-site. Assembly takes time and a basic understanding of hand tools.
What about electrical and plumbing installation? Does the sauna require an electrical power source? If so, you’ll have to run a power line to the sauna location. Most people will have to hire an electrician to complete this task.
And, if you’re purchasing an outdoor steam room you may need to install a water purification unit for the steam generator. You’ll need to take a moment to evaluate the models currently available on the market.
LOCAL REGULATIONS
Depending on the area you live in – the installation of a sauna may fall under local authority regulations. It may be categorized as a new permanent building and be subject to building codes.
The last thing you want to do is install an outdoor sauna only to receive a legal notice or fine down the road. Reach out to your local and state authorities and find out if there are any official requirements or regulations you need to satisfy for your new outdoor sauna.
OPTIONAL EXTRAS
Do you want any special additional features? The best outdoor saunas come with a range of optional extras you can have added to personalize your sauna experience. Popular features you can choose from include color light therapy, remote access, built-in sound systems, and ergonomic backrests.
• Color Light Therapy
Color light therapy, also known as chromotherapy, uses colored light to potentially boost mood, aid relaxation, and stimulate energy levels. The interior of the sauna cabin is fitted with LED lights that can be set to emit colors depending on the effect you wish to achieve.
• Remote Access & Control
The best outdoor saunas come with apps and remote access that allow you to power on and off the sauna using your phone. This means you can preheat the sauna without having to physically go outside and access the control panel itself.
• Bluetooth Sound System
A Bluetooth audio system allows you to connect your device and listen to music or podcasts while you relax in the sauna. Speakers are strategically fitted in the wall panels so you can sweat and listen to your favorite tunes all at the same time.
• Ergonomic Back Rest
Another popular add-on is an ergonomic backrest. This timber frame is placed behind your back while you rest in the sauna and it is designed to shape and optimize spinal alignment while you rest.
PROS & CONS OF OUTDOOR SAUNA
An outdoor sauna is a considerable investment. And, if you are thinking about adding one to your home, you need to know the pros and cons. Below we run through the key advantages and disadvantages of an outdoor sauna. For a more detailed guide, check out the Benefits and Disadvantages of Outdoor Sauna.
THE PROS
• BACK TO NATURE
An outdoor sauna allows you to sit back, relax, and work up a sweat in the great outdoors. What better way to get back in touch with nature than by enjoying a sauna session in your garden and backyard? And, when you need to cool down and you can step outside and enjoy some truly fresh air.
• PRIVATE RETREAT
An outdoor sauna provides a private space you can escape to when you want to get away from the everyday stresses of life. It is a stand-alone, separate space and can be used as a retreat you can relax and unwind in when you feel the need to step outside.
• RELAXATION & HEALTH BENEFITS
Outdoor saunas come with all the same health and relaxation benefits as a regular sauna. Saunas have been enjoyed around the world for centuries for their potential health and relaxation benefits – such as system detox, skin cleansing, and cardiovascular stimulating benefits.
• SAVES INDOOR SPACE
Placing your sauna outdoors means you will save space inside your home. Saunas are large devices and require lots of space. If you live in a home with limited space – your options may be limited. You can free up your indoor space by opting for an outdoor sauna and placing it in your yard or garden.
THE CONS
• INSTALLATION & ASSEMBLY
The vast majority of outdoor saunas require onsite assembly. Assembling an outdoor sauna requires a basic knowledge of hand tools and will take several hours.
There are also installation requirements to be considered. Most out door saunas need an electrical connection. If you don’t already have one, you’ll have to have an electrical power source installed in your yard.
• EXPOSURE TO THE ELEMENTS
Outdoor saunas are naturally exposed to the elements. And, if you live in a region that experiences harsh weather conditions – the sauna cabin can suffer damage over the years. Although outdoor saunas are designed to withstand most weather conditions, you may need to perform periodic maintenance over the years to prevent deterioration.
• REQUIRES OUTDOOR SPACE
Outdoor saunas require a considerable amount of free space. Not all homes have gardens or yards that can accommodate a sauna cabin. A typical 2-person sauna measures 58” x 41” x 96” inches. While a larger 4-person cabin will need 78” x 68” x 96” inches of free space.

KEY FEATURES
- Excellent Performance
- Durable Heat-Treated Wood
- Outdoor Thermal Insulation
- Full Spectrum Infrared
- Chromotherapy Enabled
- 6-Year Warranty
SUPERB PERFORMANCE
The Sun Home Luminar Outdoor 2 person infrared sauna is the best outdoor infrared sauna 2025. It performs superbly and has a compact design that will complement most gardens and outdoor spaces.
Many outdoor infrared saunas struggle to perform in an outdoor environment. They run at lower temperatures compared to traditional saunas – and this means they don’t reach optimal operating temperature during cold weather.
Not the Sun Home Luminar Outdoor. Some clever design features, thermal insulation, and the use of highly durable carbonized wood make it an excellent choice for enjoying an outdoor sauna session.
FULL SPECTRUM INFRARED HEAT
If you want to experience the best infrared sauna has to offer, then you need to choose a sauna that generates full-spectrum infrared heat. And, the Sun Home Luminar Outdoor does just that. This sauna packs a real heat punch and comes fitted with a combination of full-spectrum and far-infrared (FIR) heaters.
The heaters are strategically mounted inside the cabin to provide optimal exposure and maximum heating effect. The Sun Home Luminar Outdoor employs three far infrared heaters under the bench to heat your legs and lower body. And, there are six full-spectrum heaters positioned at a higher level around the cabin interior.
IMPRESSIVE DURABILITY
Another key quality that makes this outdoor sauna stand out from the competition is its durability. Some clever design and engineering techniques have been used to make sure the sauna stands the test of time, a vital characteristic when considering outdoor use.
The Sun Home Luminar Outdoor has been constructed using highly durable carbonized wood. The thermal modification process changes the wood’s chemical composition and makes it more resistant to weathering and decay. And, it increases its thermal insulation performance. More on this below.
THERMAL INSULATION
The sauna uses a dual wood construction for increased thermal insulation. This helps keep the heat on the inside and the cold on the outside. The cabin interior is made from cedar. This provides an authentic and visually pleasing appearance. Cedar is one of the most popular wood choices for sauna construction, and for good reason.
The exterior of the cabin is made from Grade-A carbonized wood. This wood provides a thermal insulation layer that allows the sauna to reach the temperatures you need to work up a sweat. The timber is kiln and air-dried to reduce warping and minimize the chances of cracking. And, the glass wall and door use double pane glass to boost insulation.
THE EXTRAS
Now we know how the sauna performs and how it’s made, let’s take a look at the features that come as standard with the Sun Home Luminar Outdoor 2-person sauna. These really make it stand out from the crowd.
- Chromotherapy
The sauna comes equipped with medical-grade chromotherapy. This means you can select light color to reflect your mood and help you relax.
- Panoramic View
The cabin has a full-sized all-glass wall and a glass door for a panoramic view. Greta news if you want to connect with the outdoors and enjoy a stunning scenic view.
- Bluetooth Sound System
There’s also a Bluetooth sound system that lets you connect your device. This way you can unwind while you listen to your favorite tunes or podcasts.
- Remote Control Operation
And, finally, there’s a remote control operation system. Download the Luminar mobile app and control the sauna remotely. This is a great feature for pre-heating the sauna before you use it.

BEST 2-PERSON OUTDOOR SAUNA
The Almost Heaven Salem is the best 2-person outdoor sauna in 2025. It combines a compact design, excellent build quality, and reliable performance. If you want a small outdoor sauna that can accommodate two people – this could be just the one you’re looking for. Below we’ll take you through everything you need to know.
CONSTRUCTION
Almost Heaven has been making barrel saunas for almost 40 years. The company is based in Greenbrier Valley, West Virginia and their range of outdoor saunas are USA made. If you’re looking for a sauna company with lots of experience – you won’t find much better.
The barrel is constructed using a ball-and-socket joining profile between the lumbar support. This structure allows the cabin to expand and contract as it heats up and cools down. And, the whole thing is securely held in place using a series of fasteners and stainless steel bands.
The barrel is supported on a plastic polymer cradle that holds the sauna in place and lifts it off the ground. This prevents ground moisture from seeping into the base of the sauna and also helps insulate from cold ground temperatures.
The interior of the barrel is fitted with LED lights. The lights are energy efficient and require a 110 volt, 15 amp power source. If you choose an option with a glass door or rear-facing window – the glass will be tempered.
TIMBER OPTIONS
The Salem barrel 2-person sauna is available in three timber options – rustic fir, rustic cedar, or clear cedar. And, the timber panels measure an impressive 1 ⅜” inches thick, which delivers reliable heat insulation.
• RUSTIC FIR
Fir is a great choice for people looking for an authentic nordic sauna. This choice of timber is light in color and is very popular in Scandanavia. Fir saunas have a clean, fresh look and are patterned with occasional knots in the panels.
• RUSTIC CEDAR
The rustic cedar option adds a little color to the cabin. This timber option has a warm red hue – a very popular choice of lumber for saunas in North America. Cedar is an excellent wood for sauna construction.
• CLEAR CEDAR
Clear cedar is a premium lumber choice. It has similar properties to rustic cedar but has an absence of knots. This means the timber panels have no noticeable wood knot patterns.
CAPACITY & DIMENSIONS
The Almost Heaven Salem barrel sauna has a compact design. It’s ideal for people that have limited available outdoor space. The sauna can accommodate 1 or 2 people at a time and is suitable for indoor or outdoor use. This means its compact design makes it a great addition to a home gym.
The sauna has an exterior footprint of 47” x 72” inches and it stands 77” inches high. Note, the cradle adds an additional 6” inches to the height of the cabin.
The interior dimensions measure 71″ x 39″ x 71″ inches (width x depth x height). Inside, two benches run the length of the interior – one on either side. The benches measure 39” inches long, 18” inches deep, and stand 17” inches high.
- Interior Dimensions: 71″ x 39″ x 71″ inches (width x depth x height)
- Exterior Dimensions: 72″ x 47″ x 77″ inches (width x depth x height)
- Bench Dimensions: 18″ x 39″ x 17″ inches (width x length x height)
- Cradle Dimensions: 54″ x 6″ inches
- Shipping Weight: 540 lbs
The sauna is a great fit for 2 people as long as you don’t mind sitting close together on either side of the barrel. There is plenty of room for sitting and relaxing, but the benches are not long enough to lay flat and stretch out.
HEATERS
The sauna is fitted with a Harvia sauna heater and comes complete with a stack of sauna stones. The 4.5kW heater requires a 240V, 30-amp electrical connection. And, the good news – it performs superbly.
You can expect a maximum sauna temperature of 175-185°F – in most operating environments. However, if you live in a particularly cold climate, we recommend upgrading to the more powerful 6kW Harvia heater.
The heaters come equipped with an easy-to-use control panel. There’s even a setting that allows you to delay pre-heating by up to 8 hours. And, the heater can be used for either a dry or wet sauna session. If you want to introduce a little steam, just ladle some cold water over the hot sauna stones.
OPTIONAL UPGRADES
The Almost Heaven Salem 2-person barrel sauna has several optional upgrades to choose from. Depending on how you want to use your outdoor sauna you can customize the rear vista window, heater type, door style, type of timber, and LED lighting.
• VISTA REAR WINDOW
A rear-facing window can be installed on the rear end of the sauna above the heater. This is great for homes that want to make the most of an impressive view. The window measures 20” x 36” inches in size and is made using 3/8” inch thick glass.
• HEATER OPTIONS
The Salem comes with a 4.5kW Harvia heater as standard. If you want more heating power you can upgrade to a 6kW unit.
• DOOR STYLE
You can tailor your sauna door by choosing from either an all-wood, wood with a window, fading glass, or deluxe glass sauna door.
• LED MOOD LIGHTING
You can upgrade the standard LED lighting ensemble to mood lighting for an ambient lighting effect.
• TIMBER OPTIONS
You can choose from one of three types of timber for your barrel sauna – rustic fir, rustic cedar, or clear cedar – see above for details.
WARRANTY & SHIPPING
The Salem comes with a limited lifetime warranty on the sauna cabin, a 5-year limited lifetime warranty on the heater and its parts, and a 1-year warranty on the heating elements. Almost Heaven ship saunas through the United States. If you live outside the US you will have to contact one of the company’s international partners.
VERDICT
The Almost Heaven Salem barrel sauna is our runner-up for best outdoor sauna 2025. The company are US based and has been making saunas for almost 40 years. If you want a sauna that performs well and takes up very little space – the Salem is an excellent choice.
The barrel is constructed using a secure ball-and-socket mechanism that locks the timber frames in place while allowing them to expand and contract as the sauna changes temperature. There are three lumber options to choose from – rustic fir, rustic cedar, and clear cedar – each offering a distinct appearance and set of characteristics.
The sauna comes equipped with a 4.5kw Harvia electric heater that performs well and reaches temperatures of up to 185°F. However, if you need more heating power you can upgrade to a 6.0kw unit – a good choice for people living in colder climates.
Optional extras allow you to tailor the Salem to your individual needs and include a rear-facing vista window, a more powerful heater, door style, mood lighting, and preferred timber of construction. The sauna requires onsite assembly which will take two people – approximately six hours. It’s our runner-up in the best outdoor sauna 2-person category.

The barrel cabin is constructed using tongue and groove staves that allow for expansion and contraction as the sauna heats up and cools down. The staves are wrapped in stainless steel bands and fasteners that hold them tightly in place and minimize heat loss.
A support cradle holds the barrel in place and lifts the sauna off the ground. This delivers stability to the curved structure and insulates the cabin from the cold ground below.
• ASSEMBLY
The sauna is delivered in pre-cut tongue and grooved pieces – and requires home assembly. It doesn’t require any specialist DIY skills or tools but two sets of hands are recommended. You will need a screwdriver, spirit level, drill, hammer, rubber mallet, and an adjustable wrench. The task takes between 4 and 6 hours and is guided by a user manual and video.
CAPACITY & DIMENSIONS
The Redwood Outdoors Cedar Barrel is a 6-person sauna. The interior benches measure 64” inches long.
