Outdoor Sauna Benefits

i. Improved cardiovascular health

There is a growing number of evidence that relates sauna baths to cardiovascular health.

People who take regular saunas sessions are less likely to suffer major heart attacks and minor strokes.

The reason cited for it is the stabilization of the body’s blood pressure while taking a sauna bath. 

ii. Reduce stress

The sweating during sauna improves blood circulation throughout the body, which in turn leads to the relaxation effect. 

It is almost always observed that after a regular sauna session, an uplifting feeling overcomes the body. 

iii. Reduce weight

The difference is quite unnoticeable, but the sauce does contribute to weight loss.

It boosts the metabolism of the body, and therefore, one burns more calories than normal people do.

The high rate of calorie burning is associated with the temperature of the sauna and the duration of the sauna session.

Buying Guide For Best Outdoor Saunas

The following guide will tell you what to consider before making the purchase decision. 


The first and foremost consideration should be the space available for the sauna as well as space inside the sauna.

The reason for the former is straightforward: if you have limited space in your backyard and yet you are adamant to fit a large sauna inside it, you are biting off more than you can chew. 

As far as the space inside the sauna is concerned, the number of people using the sauna at a time would be the limiting factor.

It is usually advisable to have a spacious sauna. 


As outdoor saunas are more susceptible to damage than indoor saunas (they are directly subjected to harsh weather conditions), you cannot, in any case, compromise on the construction material. 

Most preferably the sauna should be made up of Canadian Hemlock or Cedarwood.

Aspen may do well for an indoor sauna, but it falls apart as soon as it comes under the influence of extreme weather. 

Hemlock and cedar have almost the same strength: they are both highly resistant to stain and mildew.

But the cedar has an upper hand when it comes to aroma, durability, and insect resistance.

Heat source types

The heat source type is what distinguishes a traditional sauna from an infrared one. 

The traditional saunas create moist heat by pouring water on heated volcanic rocks or a stove.

The temperature of the sauna is raised due to the heat of the rocks and the steam and generally takes 30 or more minutes to heat up. 

stones inside a sauna heater

The infrared sauna on the other hand relies on the carbon and ceramic heaters to heat the body.

Unlike a traditional sauna, they don’t rely on convection to do so. Rather they directly act on the exposed skin to stimulate sweating.

If you are looking for the perfect sauna heater, here’s our pick – Top 10 sauna heaters.

Additional features

If you love bells and whistles with all the products you buy in life, why make an exception for a sauna. 

Outdoor saunas usually come with chromotherapy—using lightning to relax the body.

They are equipped with a sound system so you don’t miss out on your favorite songs while taking a bath. Also, there should be an atomizer to regularly purify the air

In case you prefer a traditional sauna over an infrared one, keep an eye for the buckets and linen (whether they are included in the package or not).


Premium companies always back their products with a warranty. It is true about the sauna manufacturing companies too.

So, you are right to expect it from the next sauna company you are going to buy an outdoor sauna from. 

For a sauna, a long warranty (a minimum of 5 years) is a sign of quality and it should always be preferred. 

Based on these criteria we choose the following outdoor saunas.

10 Best Outdoor Sauna Reviews

6. SDI Outdoor Sauna (4+ Person)

6' Foot Canadian Outdoor Pine Wood 4 Person Barrel Sauna Wet/Dry SPA w/ 9KW Electric Heater and Lava Rocks

The best thing about this sauna is that it can provide both wet and dry sauna sessions, and will be delivered incredibly fast.

Plus it can be used both indoor and outdoor depending upon space availability.

SDI has equipped this sauna with multiple extras: there is MP3/Auxiliary Audio input with a stereo system that can be controlled with remote control, there is an ionizer to purify the air and chromotherapy lighting to stimulate relaxation effect

One of the most striking features is its heavy-duty heater that takes almost half as much time as a regular heater.

On the downside, it will consume more energy to maintain the same temperature. 

On the selection of construction material, SDI has disappointed its users.

The pinewood can never be a match for hemlock or cedar.

You will have to take extra care of it, as it is essentially not built to withstand a high degree of abuse.

The company backed it with a limited warranty. For user’s convenience, it promises to deliver it as soon as possible. 


✓ Can be used both outdoors and indoors
✓ Extra fast delivery
✓ Powerful heater
✓ Backed by warranty

8. Western Pacific Outdoor Sauna (4 Person)

3 to 4 Person Outdoor Sauna Weather Resistant Hemlock Wood, Shingle Roof, 220v, 8XL Ceramic FIR FAR Infrared Heaters, MP3 / Auxiliary Input iPod, iPhone

With the accommodation space for 3-4 people, this outdoor sauna relies on infrared technology to heat the body. 

To begin with, it comes with ceramic far heaters that are strategically located for an even distribution of heat.

The ceramic is a fragile material and may add to the maintenance cost of the sauna. 

The overall frame is made out of hemlock, which though high strength, is a vulnerable material in extreme weather conditions: heavy rain or snow. 

As far as the assembly of the sauna is concerned, it takes a lot of effort to put it together.

For a single person, given he has the expertise, it might take 8-9 hours to assemble it from scratch. 

Finally, it has several extras to cater to the needs of users. To name a few, it includes chromotherapy LED lights, reading lamps, and ozone generators.


✓ The ceramic infrared heater heats up fast
✓ Include extras
✓ Backed by a limited warranty

10. Allwood Barrel Sauna (6 Person)

Allwood Barrel Sauna #220-WHC Wood Fired Heater

Allwood Barrel Sauna as the name suggests has barrel-like design and robust construction.

The definite advantage with a rounded sauna is the energy efficiency, as it has to cover relatively less space than a cornered design.
