Posted on 10 March 2025

A home sauna can be a worthwhile investment for those who are looking to improve their health and wellness routines. However, it may be difficult for homeowners to find adequate space in their homes to accommodate a sauna. In this case, an outdoor sauna kit is the perfect choice. Many homeowners are skeptical as to whether or not outdoor saunas can withstand extreme weather conditions, and the truth is, when you buy a SaunaFin sauna, there is no need for concern. SaunaFin saunas and sauna heaters are made from top-quality materials to ensure that they can withstand even the harshest Canadian weather. If you are interested in investing in a sauna for your backyard, contact SaunaFin today to begin customizing your kit.
Here is how outdoor sauna kits perform in harsh weather conditions.
Cold and Snowy Climates
Canada is well known for its icy cold winters and heavy snowfall during this time of year. During the winter months, you may find that a great deal of snow builds up on the roof and surfaces of your sauna, and for the most part, there is no need to worry. At SaunaFin, our saunas are only made with high-quality cedar and hemlock wood. The reason we utilize these two varieties is because:
- They both have excellent insulation properties. This means your sauna will still retain heat well, even when it is extremely cold outside.
- They are very durable and can withstand freezing temperatures and snow without freezing or warping.
- They are naturally resistant to moisture and will not suffer from snowfall and melting snow at the end of winter.
Purchasing a sauna kit with durable, quality wood will ensure that your sauna can withstand harsh winters and snowstorms.
Outdoor Sauna Kits in Hot & Dry Climates
The weather in North America can vary significantly from city to city, and some areas experience extremely hot and dry conditions, especially in the summer months. Wood fences and furniture are known for cracking and fading in extremely hot temperatures. This is often due to high UV exposure during this period of time. However, this is not the case for wooden saunas. At SaunaFin, our cedar and hemlock saunas are designed to last all summer long without cracking or any UV damage. However, if you are worried about extreme dryness during the summer, you can apply a sauna preservative or seal to better protect your sauna against harsh sun rays.
Rainy & Humid Conditions
Canadian spring is synonymous with heavy rain and warm humidity all season long. If you have an outdoor sauna, you may be curious as to how severe rain impacts it. As mentioned above, SaunaFin outdoor saunas are made with cedar and hemlock wood, both of which are naturally moisture resistant and anti-microbial. This means that they will repel water and deter mold and bacteria growth, even in humid conditions. If you do live in a rainy climate, then consider the following:
- Cover your sauna when not in use during periods of heavy rainfall
- When installing your sauna, place it on an elevated base in order to prevent water from pooling at the base
- Ensure there is an effective drainage system near your sauna
Extreme Weather is No Match for a SaunaFin
If you are looking to invest in an outdoor sauna kit, it is crucial to understand how the climate you live in will impact it. Rain, snow and high temperatures can all affect your sauna; however, when you invest in a quality sauna from SaunaFin, the weather is not a significant concern. At SaunaFin, our saunas are designed to withstand the elements, allowing them to last well into the future.
