Thermo Wood Barrel Sauna - Micro (2 Person) Barrel Sauna | Finnmark Sauna

Traditional Outdoor Sauna Or Barrel Sauna - Which One Is Best For You?

Choosing between an outdoor sauna and a barrel sauna comes down to your space, style preferences, and how you want to use your sauna.

Barrel saunas are known for their recognisable curved, compact design. This model is designed for those individuals or couples who value simplicity, efficiency, and a cosy, enclosed wellness experience. Also, this model usually has a smaller cost due to its size and structure. Take your wellness experience a step further and indulge in sauna scents and oils.  

In contrast, a traditional outdoor sauna model is built with a square, angled roof or flat roof design, often preferred by those who want that extra space, offering a more permanent structure. This garden sauna is ideal for larger groups and families wanting a classic sauna experience. This type of sauna allows for versatile bench arrangements, such as traditional setups or L-shaped social setups. 

Finnmark also offers sauna accessories such as stones, sandtimers, towels and robes to ensure you get the best experience possible. 

Both types of saunas allow for versatile design options, from different glass fronts to different colours and options. Ensuring your sauna is just the way you want it.

 Frequently Asked Questions

Does a garden sauna need electricity?

Most outdoor saunas require electricity, not only to power electric heaters but also to support features like lighting and other modern conveniences. Electric sauna heaters must be connected safely by a certified, licensed electrician. Typically, domestic models designed for outdoor use operate on a 240V single-phase connection, while larger commercial heaters may need a three-phase 400V power supply. Always check the recommended heater specifications for each outdoor sauna model to ensure you use the correct power supply. This electrical setup allows for precise temperature control, quicker heat-up times, and a hands-off sauna experience, ideal for those seeking convenience and consistency.

While both wood-fired and electric saunas need electricity for lighting, the wood-fired option offers a more traditional, off-grid experience. It’s perfect for those who enjoy the ritual of building a fire and want to connect with nature. The exact electrical requirements vary depending on your sauna model and heater type.

What are the wellness benefits associated with using a sauna building?

Regular sauna sessions offer a wide range of proven health benefits that go far beyond simple relaxation. The intense heat of a sauna encourages deep sweating, improves circulation, eases muscle tension, and supports immune function. These effects can contribute to better sleep, reduced stress, and even pain relief. 

Another key benefit to mention is that outdoor saunas offer the experience to reconnect with nature and provide a much-needed break from everyday distractions. Being surrounded by fresh air and experiencing the ritual of entering your outdoor sauna cabin, it becomes a sanctuary of calm.

Can external saunas be used in the winter?

Absolutely, external saunas are designed to be used all year round, including during the coldest winter months. Winter is one of the most popular times to enjoy a sauna session, as the contrast between the crisp outdoor air and the enveloping heat of your sauna enhances both the wellness benefits and the overall experience.

Although it is important to note that the heat-up time can vary between seasons, usually during the winter months, it takes a longer time for the sauna to reach the preferred temperature due to the cold outdoors. Also, the location of the outdoor sauna can have an effect on the heating performance, for example, if located on a coast or particularly windy area, the overall heat-up time may be longer.

Due to Finnmark's outdoor sauna design, superior insulation, efficient heaters, and carefully selected woods, every model maintains consistent warmth and comfort, even in freezing temperatures. Whether you choose a barrel sauna, a traditional garden sauna, or a portable sauna trailer,  each is built to withstand the elements, delivering reliable performance, exceptional relaxation.

How often should you use an outdoor sauna to experience the most wellness benefits?

To enjoy the full wellness benefits of your outdoor sauna, consistency is key. Most experts recommend using a sauna based on your comfort and experience level. Always listen to your body and use the sauna based on your abilities and preferences. 

It's advised to have a cool-down period outdoors or a refreshing shower while using the sauna, and this cycle can be repeated as many times as you require. However, more isn’t always better. Overuse, especially for beginners, can lead to dehydration or fatigue, so it’s essential to listen to your body and ease into a rhythm that feels sustainable.

Incorporating sauna use into your weekly routine, especially in the peaceful setting of your home garden or outdoor retreat, has never been easier with Finnmark's luxury outdoor sauna options.
