In general, we recommend that the sauna is used and stored indoors, in a dry and protected environment. The sauna is not designed for damp or cold conditions, which means it should not be left outside in rain, cold temperatures, or high humidity for extended periods. This can negatively affect the materials, electronics, and overall functionality.
However, it is possible to use the sauna outdoors temporarily in dry and mild weather, or place it on a well-insulated and weather-protected balcony. In that case, it’s important that the sauna stands on a level and stable surface.
For optimal durability, safety, and performance, we always recommend indoor use as the first choice.
