Bathroom Exhaust Fan

How expensive is it to put one in?

Re: Bathroom Exhaust Fan

depends cause you have to vent it to the outside....some will just vent it up into the ceiling which is very bad cause the moisture will just stay there.

Do you have a window in the bathroom? If so the fan isnt required by code and most people don't have them then.

Re: Bathroom Exhaust Fan

its easier if you can vent to the side of the house. i am doing this when we formally redo the bathrooms. We have a ranch so we can do it since we have tons of attic space to walk around to get up there to do a flex duct out. When you vent to the roof you can cause minor leaks if not done correct (one thing i refuse to diy is anything roof related.)

When we do the laundry room it was supposed to be vented out and I wasn't able to be at home to watch my BIL who did the work. He now has it vented to the attic so when we do the bathroom we will both vent to the side of the house this way if someone ever wants to build up they won't have to carry the vent all the way out.

If its something you think electrically you can't hook up then find a general handyman/electrician to do it.

Thanks, we have a window but everytime we take a shower it is just so damp in there - now the paint above the shower is peeling/cracking (partly due to mositure, partly due to poor quailty paint) I literally had to wipe down my walls/ceiling with a towel this morning it was so damp...

Re: Bathroom Exhaust Fan

just a note: no matter how much it is, GET IT

I didn't have one and their were ugly brown spots on the ceilings and a whole host of another annoying issues.

Re: Bathroom Exhaust Fan

yea i agree put a fan in we know when we open the walls the drywall will be filled with mildew/mold. Even with mold resistant paint unless you used newer water resistant drywall/vapor barrier your going to get moisture/mildew.

Re: Bathroom Exhaust Fan

When we had our bathroom redone several years ago, I told the contractor that I wanted a vent. He tried to tell me that code doesn't require a vent since we have a window. I then had to explain to him that when it's 15 degrees below zero and a blizzard outside, I am NOT going to leave the window open when I'm taking a shower!

If you can vent it to the wall, it's fairly simple. If you have to go out through the roof, it may be more involved. Definitely don't vent it into the attic. You're dumping hot, wet air into a cold zone, and it will immediately turn to frost inside the attic during the winter. In the summer, you'll be causing mold, since mold loves warm, wet environments.
