Tips for Installing a Bathroom Exhaust Vent Fan

We installed ultra silent Broan-NuTone vent fans in the bathrooms of the Kuppersmith Project house, to remove moisture from the air and prevent mold from forming after showering.

When installing a bathroom vent fan, be sure to:

  • Choose the right size vent fan for your bathroom.
  • Vent the fan to the outside, instead of the attic.

Danny Lipford: What you put into making your house a home takes a lot of time and patience, so make sure you choose something that’ll stand up for years to come. Here’s a great example from Broan-NuTone.

Mike’s trying to be sure he matches the right NuTone vent fan with the right bathroom, because each has a specific style and is designed to move a specific amount of air.

Danny Lipford: Now Mike, I wonder how many Broan-NuTone exhaust fans you’ve installed over the years.

Mike Gengo: Oh, probably several hundred.

Danny Lipford: Yeah they’ve been around a long, long time. They’ve got them now where they’re so darn quiet that some of them even have to have, I understand, like lights on the switch for you to even know that they’re even turned on.

Mike Gengo: That’s right. That way you won’t be leaving it on. It’d be sucking all the air conditioning right out of your house.

Danny Lipford: Yeah, exactly. Now I guess the sizing of these things is real, real important because of course, this is a very small bathroom right in here but a lot of people just undersize those things, don’t they?

Mike Gengo: Yeah they do Danny. You know, you want to make sure that you get the proper size unit, so that it will pull the steam and the moisture out of your bathroom. Otherwise, you get some cracking in your molding and you get mold.

Danny Lipford: I never understood people venting these things in the darn attic. I mean I know people don’t want to have another hole in their roof but why would you want to put everything right up in your attic?

Mike Gengo: Yeah. That’s a question you’ll have to ask somebody else because I don’t know.


  1. I have installed a bathroom fan in my house, my wife swears that we get better flow out the vent with the door shut and air coming up thru the cloths chute. I think it’s better with the bathroom door open.
