When investing in something like an outdoor sauna kit, you’ll want to ensure that you take the measures necessary to extend its useful life as long as possible. Saunas in Canada are especially susceptible to weather damage, given the diversity of our climate. However, taking the right precautions can help reduce the impact of the weather on your outdoor sauna. Investing in a high-quality sauna can also contribute greatly to the longevity of your sauna.

Invest in a Quality Product
One of the best ways to ensure that your sauna can withstand weather damage is to invest in a high-quality outdoor sauna kit from a reputable manufacturer. Ensuring that your sauna is built with durable materials will help prevent damage from rain, ice and extreme temperatures.
Sauna kits made of cedar wood are usually highly recommended because of their durability. Cedar wood naturally contains a lot of oils, contributing to a natural water resistance which can help deter wood rot and mold growth. This is especially beneficial since saunas can get humid with use. Cedar is also known for its strength, as it does not break, chip or crack easily, allowing it to hold up well in extreme temperatures. Overall, investing in a quality sauna is the best way to ensure your cedar sauna holds up against the weather; however, some other strategies can help as well.
Metal Roof Option
Many outdoor saunas in Canada offer a metal roof option, which can be a wise investment, especially when it comes to protecting your sauna against weather damage. A metal roof creates a barrier between the actual wood of your sauna and the elements. This helps reflect heat and light off of your sauna, helping reduce the risk of warped wood. Metal roofs also prevent water from pooling on the roof of your sauna, preventing water from seeping in through the roof. This can also deter wood rot and mold growth. Metal roofing also allows for snow and ice to be easily removed from the top of your sauna in the winter, reducing the load on it.
Sauna Cover
If you do not plan on using your outdoor sauna kit throughout the winter, then it is best to cover the sauna with a tarp to protect it against the harsh weather. This will ensure that frost and mildew do not build up on the outside of your sauna.
Vapour Barrier
A vapour barrier prevents moisture from penetrating and damaging your sauna’s insulation or wood framing. This needs to be applied during the sauna installation process and will help avoid humid weather or rainwater from damaging your outdoor sauna.
