It looks like the bottom of this sauna rests directly on the floor? I'm looking at putting one in a corner of our heated garage on a cement floor (we're in Maine on the shore and the humidity gets really high and our winters are brutal!) Should I think about putting down some kind of moisture barrier and if so, what would you recommend?
There is a floor in the infrared sauna and it is raised slightly off the floor with hidden runners underneath the floor.
Moisture in a setting as described is not likely to be an issue.
