Dude, you can go through the soffit with no problem. You aren't venting a fricking dryer
Just save a frickload of time and not run a vent at all and let that shite go in the attic. I mean, it's not a fricking dryer or anything, right?

I have a light fixture/fan in my shower. Not sure of the wiring above. It def keeps moisture from accumulating on painted shower ceiling.

But if it's venting an area with a shower then there's a high probability of moisture. You don't want that in your attic.

make sure you cut a hole in the roof and vent that thing out of the house (per codes)


I don't think that's code

i think he was being sarcastic.


I get what jeep's saying. If you are going to do it do it properly. With that said I'm just trying to get this house in shape to sell.


I know having no exhaust fan at all is bad and will be a mark against the bathroom. But i'm assuming having an exhaust that vents out of a soffit instead of the roof isnt going to scare buyers away. And wont be a mark against the house during inspection.

Yeah I ran mine out at the soffit and haven't had any issues. I would agree that having one is better than not... and running it out at the soffit is better than cutting a new hole in the roof.

Well i havent inspected it yet but the ole lady says the existing vent is just venting into the attic.


I would check that first... you know women are dumb.

But even if you have an existing vent line is it a good idea to tie into that? I'd be worried about one fan exhaust backflowing to the other fan. Seems like you'd need some kind of check valve/flapper on each line coming from a fan before the point where they join to a common line... path of least resistance and all.

You could end up blowing shite fumes right back into the bathroom.

If you are just trying to sell the house I wouldn't worry about this shite at all. I've never asked about the exhaust fans in a house I'm about to purchase. If the buyer asks, put one in.

I really have no idea. Good question.

I'm a big fan of the "frick 'em" approach.

Baffles. Just like I said earlier.

Have you tried leaving the door to the toilet room open w/ the fan on? Seems like it would still be able to help w/ moisture removal from the shower... unless it's really far away.

If you must go w/ the 2nd fan route, I'd say just run a separate line from that fan to the soffit. And check the existing fan to make sure it's not running into the attic.

If you don't want to make 2 vents in the soffit, I would join the 2 fan exhaust lines together as close to the soffit as possible to help prevent backflow.

I'd go this route as well if I was you. It will only take a couple of months for mold to start growing if you do get moisture coming back into the attic and you say you may be there for a year or two. I'd do it correctly or not at all.

To do it correctly it is NOT hard at all. You could probably find youtube vids on how to do it and see how easy it is.

It took me less than 2 hours and I was tying into another exhaust fan.

Well if the other fan has been venting into the attic this entire time without issue, who would venting thru the soffit suddenly make a difference?

Also, couldn't he put the exhaust vent away from any of the soffit vents? He doesn't have to put it right next to it.

Yeah, it is not hard but I can understand why someone who has never done it would think it may be difficult.
