Hot Tub In Garage

I have a customer who wants to put a hot tub in their garage. The garage is on a new house and is already insulated and sheetrocked. The main concern I have is what to do about the steam the hot tub will put out. Do I need to tear out the sheetrock around and above where it will be and install moisture resistance sheetrock? Do I just put in a good exhaust fan? Any advice is appreciated. Thanks

Re: Hot Tub In Garage

You should check with your AHJ "Authority Having Jurisdiction" to find out the code requirements before assuming that it's permissible before installing.

To many safety factors to consider...such as children downing because of not being supervised or any barriers to prevent them from entering the hot tub, electrical hazards, chemical hazards from the hot tub (chlorine/bromine).

Your a little vague in mentioning what type of hot tub and I'll take it as being a portable hot tub/spa and not one of those inflatable spas that you can plug and play.

I'd personally try to talk your clients out of this and install it outside if at all possible.

Re: Hot Tub In Garage

Fix a good exhaust fan. Garage exhaust fans can stop the danger of high amounts of hazardous fumes from accumulating in the air inside the garage. This severe risk can cause numerous health troubles and even death. An exhaust fan also eliminates humidity and keeps the area dry, which prevents condensation from building up and causing additional problems.

Re: Hot Tub In Garage

I had a hot tub in a garage for years, no problem. Hoever, it does require a little common sense, like opening the door when in use, and keeping the cover on when not in use.

Re: Hot Tub In Garage

You're asuming all the liabilty for having the hot tub inside?
Also, I would be concerned about the slab thickness.
Do you have manufacturers specs?

Re: Hot Tub In Garage

Dehumidification and Air Exchanger are the correct things to consider. Humidity levels need to be controlled if you want a prof installation, I would be setting up a meeting with my HVAC guy, GMOD

All the above like genecarp says. Don't count on the owner telling you "we'll turn on the fan & open the window when we use it".
