The 7 Best Outdoor Saunas for Your Backyard

Read our comprehensive list of the 7 best outdoor saunas in order to decide which one is best for your needs including the best overall, budget friendly and more.

Outdoor saunas range from compact 2-person barrel kits to full 8-person cabin structures with changing rooms, and knowing your budget, space, and heat preference quickly narrows the field. This guide covers barrel saunas, cabin saunas, pod saunas, and glass-front designs from brands including SaunaLife, Dundalk Leisurecraft, and True North, so you can compare real specs side by side and find the right fit.

How to Choose the Best Outdoor Sauna for You?

Before you commit to a sauna kit, consider these key factors. Each one affects what you’ll end up with, and how much you’ll enjoy it.

• Size: Outdoor saunas range from cozy 2-person cabins to spacious 8-person enclosures. Think about how many people you’ll use it with regularly, and factor in bench space and room to move. Outdoor sauna capacity claims are often optimistic, so measure your space before ordering.
• Budget: Prices vary widely by size, materials, and features. Entry-level 2-person models are lower-priced; mid-range 4- to 6-person saunas cost more; premium 8-person models with changing rooms or glass fronts are a larger investment. Factor in assembly, electrical work, and any foundation prep when setting your total budget.
• Foundation and Base: Outdoor saunas require a level, load-bearing base. Options include concrete slabs, gravel pads, or pressure-treated wood decking. Always confirm the weight rating of your intended base with a local contractor before installation.
• Electrical Requirements: Most electric outdoor saunas require a dedicated 240-volt, 40- to 60-amp circuit installed by a licensed electrician. Wood-burning models avoid this requirement but need proper chimney clearance, typically 18 inches from combustibles. Budget for electrical rough-in costs, which vary by region and project complexity, if you don’t have an existing circuit.
• Permits: Many municipalities require a building permit for permanent outdoor structures. Check local zoning rules before purchasing. Barrel saunas on skids are sometimes classified as temporary structures and may be exempt, while cabin saunas on a concrete slab typically require a permit.
• Heater Size: Match heater output (kW) to your sauna’s cubic footage. A general rule is 1 kW per 45 cubic feet of sauna space. Brands like HUUM and Saunum offer electric heaters in ranges that pair well with mid-size outdoor cabins, and our team is happy to spec the right heater package for your build.
• Traditional vs Infrared: Traditional saunas use a sauna heater to warm the air, creating a dry heat experience well-suited to communal sessions. Infrared saunas use infrared heaters that warm your body more directly, which some users find comfortable at lower air temperatures, and are a popular indoor and compact outdoor option. Read more in our comparison between infrared and traditional saunas.
• Type of Wood: The wood species affects durability, aroma, and long-term weather resistance. Dundalk Leisurecraft uses Eastern White Cedar, which is naturally antimicrobial and resists warping in humid climates. Thermo-treated spruce, thermally modified at high heat with no chemical treatment, offers comparable rot resistance and is used in SaunaLife’s exterior cladding. Hemlock is a solid budget option for interior benching but is less weather-resistant for exterior use.

1. Best Overall Outdoor Sauna

SaunaLife 8 Person Outdoor Barrel Sauna W/ Changing Room

Pros & Cons

Specifications

Why We Recommend It:

The SaunaLife 8 Person Outdoor Barrel Sauna with Changing Room (Model G11) is a well-considered option for anyone who wants a spacious, social outdoor sauna without sacrificing practicality. It comfortably seats up to 8 people, making it a natural fit for families or regular gatherings. The Thermo-Spruce exterior is thermally modified to resist moisture and UV degradation without chemical treatment, making it well-suited for year-round outdoor use in wet or snowy climates.

The integrated changing room, a feature most barrel saunas at this price point lack, means you won’t step barefoot across a cold deck between sessions. At approximately 2,200 lbs, it needs a foundation rated for that load, so confirm your base with a contractor before ordering.

2. Best Two-Person Outdoor Sauna

Dundalk Leisurecraft Canadian Timber MiniPOD

Pros & Cons

Specifications

Why We Recommend It:

The Dundalk Leisurecraft Canadian Timber MiniPOD (CTC77MW) is a strong pick for anyone with a smaller backyard or who wants a dedicated 2-person outdoor sauna without a large footprint. The MiniPOD’s curved pod geometry distributes heat more evenly than a flat-walled cabin of the same floor area, and the Eastern White Cedar interior releases a pleasant natural aroma that intensifies with heat. This sensory detail distinguishes it from hemlock or spruce interiors.

At about 1,400 lbs, it can sit on a reinforced deck or gravel pad without a full concrete pour, making it one of the more installation-friendly options on this list. Ventilation needs may vary by climate, so factor that in if you’re in a particularly humid region.

3. Best Large Group Outdoor Sauna

SaunaLife CL12G 8 Person Outdoor Cube Sauna

Pros & Cons

 

Specifications

 

Why We Recommend It:

The SaunaLife CL12G (Model CL12GCP) is built for households that sauna in groups of six or more and want the space around the sauna to work as hard as the sauna itself. Instead of a single heated room, it’s a three-room suite: an 8-person sauna room, an unheated dressing room that buffers the hot room from outdoor air, and a covered porch with Thermo-Spruce benches for cooling down between rounds.

The sauna room measures roughly 340 cubic feet. By the 1 kW per 45 cubic feet rule, that suggests a heater of about 7.5 kW, but SaunaLife recommends a 10.5 kW-class heater to offset heat loss through the glass doors and back window. Plan your electrical circuit around that higher output. At about 3,100 lbs, it also needs a concrete slab or engineered pad rather than a standard deck, so confirm your base with a contractor before ordering.

4. Best Barrel Sauna

Dundalk Leisurecraft CT Serenity MP Barrel Sauna

Pros & Cons

Specifications

Why We Recommend It:

The Dundalk Leisurecraft CT Serenity MP (CTC2245MP) is a classic cedar barrel with one meaningful upgrade: daylight. Upright half-moon windows flank the front door, and a horizontal half-moon window runs across the back wall, so light reaches the benches from both ends. Most barrel saunas have a single small door window and feel enclosed by comparison.

The rounded barrel shape keeps the interior volume compact, at roughly 184 cubic feet. The 1 kW per 45 cubic feet rule points to about 4 kW, and Dundalk’s 6 kW recommendation adds headroom for the extra glass. The covered front porch with two seats gives you a sheltered spot to cool down between rounds. If you want an efficient, traditional barrel that doesn’t feel closed in, the Serenity MP delivers.

5. Best Barrel Sauna with a View

SaunaLife 6 Person 7’ Long Barrel Sauna Glass Front

 

Pros & Cons

Specifications

Why We Recommend It:

The SaunaLife 6 Person 7’ Long Barrel Sauna Glass Front (Model E8G) takes the classic barrel sauna format and adds a tempered glass front panel that is double-paned on the E8G model, which limits heat loss through the facade, a common concern with glass-front designs, while still delivering the panoramic outdoor view that makes this model distinctive.

The Thermo-Spruce exterior handles moisture and UV exposure without chemical treatment, and the Nordic spruce interior benching stays comfortable at full sauna temperature. This is the only model on this list that meaningfully blurs the line between a sauna and an architectural garden feature, worth considering if curb appeal or a specific sightline toward a pool or treeline is part of the purchase decision.

6. Best Compact Sauna

Dundalk Leisurecraft Canadian Timber 2-3 Person Granby Cabin Sauna

 

Pros & Cons

Specifications

Why We Recommend It:

The Dundalk Leisurecraft Canadian Timber 2-3 Person Granby Cabin Sauna (CTC66W) is a practical entry point for buyers who want a traditional outdoor sauna experience without a large footprint or a complicated installation. The Granby’s 6×6 ft footprint is small enough to fit on most standard decks or patios without a permit in many jurisdictions (verify locally), making it the lowest-friction option on this list for buyers who want to avoid construction.

Eastern White Cedar construction offers natural weather resistance and a pleasant aroma that lasts through years of outdoor use. Assembly is straightforward, and its compact size means you won’t have to wait long for the sauna to heat up.

7. Also Worth Considering: The Leil Black Cube

If you’re drawn to a more contemporary aesthetic, the Leil Black Cube is a cube-format outdoor sauna worth a look. The box-shaped silhouette and dark exterior finish set it apart from the curved barrel and pod designs that dominate the category. Cube saunas tend to maximize usable floor space relative to their exterior footprint, and the Leil Black Cube pairs well with modern architectural styles. Contact us if you’d like to discuss how it compares to the barrel and cabin options above for your specific space.

Frequently Asked Questions About Outdoor Saunas

Here are answers to the questions we hear most often from buyers choosing their first outdoor sauna.

Q: How much does an outdoor sauna cost?

Entry-level 2-person outdoor saunas represent a lower initial investment. Mid-range 4- to 6-person models cost more, and premium 8-person models with changing rooms or glass fronts cost even more. Factor in electrical installation if a 240-volt circuit isn’t already in place, and budget for any foundation work your site requires. Contact us for current pricing on specific models.

Q: Do I need a permit to install an outdoor sauna?

It depends on your municipality and how the sauna is installed. Barrel saunas on skids are often classified as temporary structures and may not require a permit. Cabin saunas on a concrete slab typically do. Always check local zoning codes before purchasing, the answer varies more than most buyers expect.

Q: How long does it take to heat an outdoor sauna?

Heat-up time depends on the sauna’s interior volume, the heater’s output, and the ambient temperature. A well-matched heater, roughly 1 kW per 45 cubic feet, will reach session temperature faster than an undersized one. Wood-burning stoves tend to take longer to reach temperature than electric models but provide a more traditional experience, including the ability to generate löyly, the steam produced by pouring water over hot sauna stones. Ask us about heater sizing for your specific model.

Q: What is the best wood for an outdoor sauna?

Eastern White Cedar is the top choice for outdoor use. It’s naturally rot-resistant, aromatic, and stable through humidity swings. Thermo-treated spruce, thermally modified at high heat with no chemical treatment, offers similar weather resistance and is used in SaunaLife’s exterior cladding. Hemlock is a reasonable budget option for interior benching but is less weather-resistant for exterior applications.

Q: Can I use an outdoor sauna year-round, including in winter?

Yes. Outdoor saunas are designed for year-round use. In cold climates, a higher-output heater compensates for heat loss through the walls. Thermo-Spruce and Eastern White Cedar exteriors handle freeze-thaw cycles well. Allow extra heat-up time in sub-freezing temperatures, and consider a sauna kit with thicker wall construction if you’re in a particularly harsh climate.

Q: What’s the difference between a barrel sauna and a cabin sauna?

Barrel saunas have a rounded cross-section that reduces interior air volume, leading to faster heat-up times and efficient heat distribution. Cabin saunas offer more headroom, a more traditional rectangular aesthetic, and are easier to configure with features like changing rooms or large windows. Pod saunas sit between the two, they share the curved geometry of a barrel but often offer more interior volume and a more architectural exterior profile.

Q: Are there outdoor sauna options that don’t require a 240-volt circuit?

Wood-burning models, like those compatible with the Harvia M3 stove, avoid the electrical requirement entirely, though they need proper chimney clearance, typically 18 inches from combustibles. If you’re installing a sauna at a cabin or rural property without easy access to electrical panels, consider a wood-burning sauna kit.

Electric models typically require a dedicated 240-volt, 40- to 60-amp circuit installed by a licensed electrician. Some infrared saunas are available in 120-volt plug-and-play configurations, making them an option for buyers who want to avoid electrical work entirely. However, these are typically sized for indoor or covered outdoor use rather than full outdoor exposure.
