Do Saunas Cause Mold?
September 17, 2013 by Debra Lynn Dadd
Question from Abner
I've seen a few sources--including a fine book written by Holmes (the contractor & house inspector guy)--that advise against installing saunas in houses because they can cause trouble (e.g., mold) by introducing too much moisture into the house. In that regard, another source lumped saunas in the same category as indoor pools, indoor hot tubs, and steam showers. But surely saunas do not create nearly as much moisture as those other items do? Debra, do you think it safe to install a sauna in a house? Thank you.
Debra's Answer
A sauna can contribute to mold growth in a home, particularly in a humid climate. If you do decide to use one I would make sure you find someone to install it who is very well informed about mold prevention.
