For those who are building their saunas in areas known for mice and other rodents, it’s important that we prep our build to keep these critters from nesting under our sauna buildings.
Further, there’s a tribe of sauna enthusiasts who are building their saunas with decking as their hot room floors, thin pencil width spacing between their 5/4″ round or 2x decking material. This method is certainly doable, but if one is building their hot room floors with an opening to the world below, AND their locale is home to mice and other rodents, we have to take care to isolate our buildings from any infultration.
Thanks to Bill, who is just now completing his sauna build. He has information for us and here it is:
Hope that you are well. I did my research and am confident that I have a solid multi pronged solution for keeping my deck floor sauna free of critters. I spoke with a number of people and was directed to a number of websites. Below are the two that were the most practical and helpful.
Techniques and methods to prevent and exclude rodents from entering structures by Rex O. Baker, Gerald R. Bodman, and Robert M. Timm.
The technique that I’ll use is found further down in the paper/article. It is the use of 1/4″ mesh that is attached to the building and buried into the ground below the depth that they will dig. Here is a drawing from the article:
The next article describes an inexpensive and easy to install metal flashing for the base of the walls and under the exterior door that I also plan to do. It can be purchased at Home Depot. Here is a photo from the article:
Here is a drawing from the previous article for how to protect entry from under a door:
We build our saunas once. Securing the perimeter of our sauna buildings in this fashion is the best way to ensure that we keep rodents away. This ensures that when we toss water on the sauna rocks, we get only “ahhhhhh” and no “ewwwwww”.
