Indoor Portable Hot Tub?


Recommended Posts


I received a Coleman Saluspa as a gift, live in Ohio.  I didn't want to wait till spring to try it out, so set it up in my garage/mancave.  My garage size is 2 car, heated, refinished with drywall which is painted with basic flat latex and has outdoor carpet.  Basic temp of my garage this time of year is around 55 degrees with 30% humidity.  I only use the spa for about 30 minutes at a time, when I run the spa the garage temp jumps to around 65 degrees with 65% humidity and the walls get a little condensation.  After using the spa I covered it back up and after about a hour the temp / humidity goes back to normal and condensation goes away.

Is this safe?  I have read about dry rot and other problems that can occur, but not sure if this would be the case using it like I am.  Will probably move it outdoors come spring.  Any input appreciated!

For what you are doing you are fine. If you plan on moving it back in side next winter I would repaint with a bath or kitchen paint that has a mold inhibitor and consider installing an exhaust fan with a humidistat. If the garage was built and insulated properly it should have a vapor barrier to protect the framing from the increased humidity and should have adequate ventilation in the attic to protect roof.
