Outdoor Saunas: Types, costs, and how to build the perfect nature retreat

The tradition of sauna culture is deeply rooted in the Nordic lifestyle, and for many scandinavian, an outdoor sauna is the perfect way to connect with nature, relax, and embrace the minimalist ethos.

Whether you’re dreaming of a peaceful retreat in your backyard or a cozy hideaway by the lake, outdoor saunas offer a unique way to unwind. In this guide, we’ll explore everything you need to know about outdoor saunas, including types, costs, and how to build your own nature retreat.

What Is an Outdoor Sauna?

An outdoor sauna is a standalone heated structure placed outside, typically made from wood and powered by either a wood-burning stove, electric heater, or infrared panels. Designed for relaxation, detox, and wellness, outdoor saunas offer a peaceful retreat in natural surroundings—whether in your backyard, by a lake, or at a cabin. They come in various shapes and sizes, from compact barrel saunas to larger prefab saunas.

What Types of Outdoor Saunas Are There?

There are several types of outdoor saunas to consider, each offering a unique experience:

Wood-Fired Saunas: The most traditional type of sauna, heated by a wood-burning stove. This option gives the most authentic sauna experience, with the scent of burning wood and a gentle crackle adding to the atmosphere.
Barrel Saunas: A popular design that resembles a large barrel, often made from wood. The rounded shape allows for efficient heating, and barrel saunas are typically smaller, making them ideal for compact spaces.
Mobile Outdoor Saunas: For those who love flexibility, mobile saunas are built on wheels, making it easy to move them from one location to another. This is great for those who want the option to bring their sauna to different nature spots or seasonal events.
Infrared Saunas: These saunas use infrared light to heat the body directly rather than warming the air. Infrared saunas are more energy-efficient and are known for their health benefits, like detoxification and muscle relaxation.

How Much Does an Outdoor Sauna Cost?

The cost of an outdoor sauna can vary significantly depending on the type, size, and materials used. On average:

Small Barrel Saunas: €2,000 – €6,000
Wood-Fired or Electric Saunas: €3,500 – €10,000
Luxury or Custom Saunas: €10,000 and above

Don’t forget to factor in additional costs such as delivery, installation, and any necessary site preparation.

Can I Install an Outdoor Sauna Myself, or Do I Need Professional Help?

Many outdoor saunas, particularly prefab kits, are designed for easy assembly, making it possible to install them yourself if you have basic construction skills.

However, if your sauna requires special electrical or plumbing work, it’s wise to hire professionals to ensure safety and proper setup. If you opt for a custom-built sauna, it’s best to consult with a professional builder.

How Are Outdoor Saunas Heated?

Outdoor saunas are typically heated using wood-burning stove:

Wood-Burning Stove: For a traditional sauna experience. This method requires firewood and regular monitoring to maintain the temperature. Highly recommended.
Electric Heater: A low-maintenance option that allows you to adjust the temperature easily with a thermostat.
Infrared Panels: These provide a different sauna experience, as the infrared light heats the body directly without making the air as hot. This method consumes less energy than traditional electric heaters.

Where to Place an Outdoor Sauna?

Location is crucial when setting up an outdoor sauna. Here are some factors to consider:

Privacy: Choose a secluded area, either in your backyard or near natural surroundings like trees or water, for the most relaxing experience.
Proximity to Utilities: If you’re using an electric sauna, ensure it’s close enough to a power source.
Ventilation and Drainage: Make sure the area is well-ventilated and has proper drainage to avoid moisture buildup.
Access to Nature: Placing your sauna near water, such as a lake or pond, allows for an authentic sauna experience with a refreshing dip in between sessions.

How to Build an Outdoor Sauna?

Building an outdoor sauna requires careful planning, especially if you want to do it yourself. Here’s a quick overview of the process:

Choose the Location: Find a spot with privacy and good drainage.
Pick a Design: Decide whether you want a wood-fired, electric, or infrared sauna, and choose a design that fits your space.
Gather Materials: Most saunas are built from wood, with cedar being a popular choice due to its durability and resistance to moisture.
Build the Foundation: A stable foundation is essential, whether it’s a concrete slab or a raised wooden deck.
Assemble the Sauna Kit: If you’ve purchased a DIY kit, follow the instructions to assemble the sauna, starting with the base and walls, and finishing with the roof.
Install the Heater: Depending on the type of sauna, install the wood stove, electric heater, or infrared panels.
Finishing Touches: Add benches, windows, lighting, and ventilation to complete your sauna.

What is the Best Material for Building an Outdoor Sauna?

Wood is the most popular material for saunas due to its natural insulating properties and ability to withstand high temperatures. Cedar, spruce, and pine are commonly used. Cedar is often preferred because it’s resistant to decay and has a pleasant aroma, while spruce and pine are more affordable alternatives that also perform well in sauna environments.

How Much Space Do I Need for an Outdoor Sauna?

Outdoor saunas come in various sizes, but most compact designs require a space of around 4 to 6 square meters. However, if you’re planning to host larger groups or want additional amenities like a changing area, you’ll need more space. Always leave extra room around the sauna for ventilation and safety.

Can Outdoor Saunas Be Used Year-Round?

Absolutely! Outdoor saunas are designed to be used in all seasons. In fact, many people in the Nordic countries enjoy saunas even more during the cold winter months. With proper insulation and heating, outdoor saunas can provide warmth and relaxation no matter the weather.

How to Maintain and Care for an Outdoor Sauna?

Outdoor saunas are relatively low-maintenance, but regular care will extend their lifespan:

Clean the interior regularly with mild soap and water.
Inspect the stove or heater annually to ensure it’s functioning properly.
Treat the wood with a sealant or oil to protect it from the elements.
Check for moisture to avoid mold or mildew buildup, especially if the sauna is near water.

How to Get Started with an Outdoor Sauna?

Choose the Location: Find the perfect spot in your backyard or at your summer house.
Determine Your Budget: Decide how much you’re willing to spend and whether you prefer a prefab kit or a custom-built sauna.
Research Builders and Models: Look for local manufacturers in the Nordics, such as Harvia, or explore models that fit your needs.
Plan for Utilities: Decide how you’ll heat the sauna and whether you’ll need professional help for installation.
Build or Order: Once everything is in place, start building or schedule delivery.

Outdoor saunas are the perfect way to reconnect with nature and embrace the time-honored tradition of sauna culture in the Nordics. Whether you’re looking for a peaceful backyard retreat or a cozy lakeside sanctuary, there are plenty of options to choose from.

With the right planning, materials, and setup, you’ll soon be enjoying the relaxation and health benefits of your very own outdoor sauna.
