Can I put a hot tub in my garage?

I have a newer house, built in 2003 with a 2-car garage. I was looking at boxing in an 8'x8' room in the back right-hand corner of my garage to put in a hot tub (something like a 5-7 person). My questions are the following:

1.) Can I safely put in a hot tub in my garage without ruining my garage walls and ceiling with are sheetrock? I am afraid the moisture from a hot tub will saturate the walls and ceiling and ruin the sheetrock thus causing mildew/mold, etc over time.

2.) Most of these hottubs need a 50amp breaker so I would need to run new electric to it. Is it legal to run a new electric line on the outside of your garage walls to get to the hottub? My electric box is in the front left corner of my garage and I want to put the hottub in the rear right hand corner of my garage.

3.) What are the BEST hottubs to look into? any chance I can get a 5-7 person hottub new and delivered for around 3k?

Thanks!

I would not recommend installing a hot tub in your garage for the reasons you cited. Mold and mildew protection would be a full time job. I am sure they make weatherproof electric cable that could be run as you want to. I am not an electrician though so you would have to check on that. Price goes with your taste and all the "toy" you want to include. You would want the best filtration system you can get. Good luck.

you would think even if using a water sealing paint on the walls that I still could get mold and mildew in my garage?

Unless you install a really good exhaust system, no matter what paint you use, mold will come to a damp environment. Being a hot tub, I assume you will keep it heated at all times so it will always put moisture into the air.

well they don't put moisture in the air when the cover is on them... only would be putting moisture in the air for about an hour a day when I use it

If you are willing to tear down the existing sheetrock for the area (including the ceiling) and install 'greenboard', which is rated for use in high humidty locations (like bathrooms and showers).

> Is it legal to run a new electric line on the outside of your garage walls to get to the hottub?

As long as it is completely enclosed in conduit, I don't see a problem.

> any chance I can get a 5-7 person hottub new and delivered for around 3k?

Not likely. Last _quality_ hot tub I looked at in the 5-7 person range was about $7000, not including delivery/setup/electrical/options

You could get a refurbed unit though in that area (again, not including delivery, etc..)

Smile Article on indoor hot tubs.

There are articles on indoor installation of hot tubs at http://www.spaspecialist.com/spacaretips.html

Need to put in high CFM ventilation and moisture proof the walls and cieling. Have a floor drain installed that can take a lot of water all at once. After about 10 years it may have a blow out.


2.) Most of these hottubs need a 50amp breaker so I would need to run new electric to it. Is it legal to run a new electric line on the outside of your garage walls to get to the hottub?

Just run the wires in proper conduit on any exposed wall.

Haven Spas are the best hot tubs in current production in this country.

Thanks!

Thanks, the spa dealers tell me that I really don't have to worry about the moisture at all, in fact all I have to do is just crack the window which is on the oppostive side of the garage from where my spa will be, and this will take care of the humidity issue when using the spa. When the cover is on the spa, they say no moisture or humidity gets out. I would still paint my walls with some sort of moisture resitant pant though, but I don't think I will need to rip down the sheetrock and put up greenboard or install an exhaust fan according to them

Your dealers are doing you a disservice. Look at how much humidity is released when you take a shower, or even a bath. Are we are talking volumes more water. As long as the cover is on, and as long as there are no bubbles going, then yes, humidity release will be minimal. Once the cover is off and the bubbles are going, there's going to be enough humidity to drip from the ceiling.

It doesn't matter what you paint the walls and ceiling with. Mold will grow on the paint without sufficient air movement/moisture removal. A window on the opposite side of the garage will not do it. Think about this: Bathrooms use 50 or more CFM fans to keep them dry. I think your garage is a bit bigger than most bathrooms.

exactly, being that the garage is much bigger than the bathroom (21' x 24' x 8' ceiling), there is a WHOLE LOT more air to saturate first BEFORE condensation begins and moisture starts sticking to the walls and ceilings. Remember condensation will only begin once the air is fully saturated and can no longer hold moisture. So therefore, with this much air in the garage, it would take in my opinion a long time to get the air that saturated, and then if you just open the garage door for a few minutes after using the hottub, this should allow all the moist air from inside the garage to escape and new fresh dryer air to enter...

Indoor hot tubs & ventilation

Any changes to the structure of the home would require a building permit, including walling off a room in the garage. Check with the local building inspector before proceeding with the project.

Ventilation is an issue with indoor tubs. If installing in home, a ventilation system to the outdoors will be required. If a room is poorly ventilated, vapors containing un-sanitized bacteria may fill the enclosed air space. In particular, the breathing in of vapors containing un-sanitized "mycobacterium avium" may cause a very uncommon infection known as "Hot Tub Lung." Rooms with poor ventilation and high humidity also develop both hidden and visible unhealthy mold and mildew. It is not uncommon for hot tubbers to report fatigue, aching , coughing, touble breathing, skin rash, and just all around not feeling good. It takes just 24-48 hours for mold and mildew to grow. And, it can grow inside wall cavities. Walls would require greenboard installed over vapor retarder.

Hot tub sales persons who say you can just crack a window, do not care about the customer. They just want to sell a hot tub for commission.

Hot tubs are a major investment and need to be in a pleasant setting either indoors or out. Sitting in the garage does not seem to be very appealing. If adding a room onto your home is not in your budget, then an outdoor hot tub is an option. Outdoor tubs cost less considering the cost of ventilation system and loss of interior space. And, you can enjoy the outdoors in a comfortable temperature whether it's raining or snowing.

Another option would be to switch out your existing bath tub to a luxury heated, jetted tub. Again, the bathroom would require adequate ventilation to the outdoors.
