Bathroom exhaust ceiling fan - old house

[aic]

1950 house with no exhaust ceiling fan in the bathroom. The remodeler stated that a fan coul dbe installed and vented into the attic. Good idea? How about the attic air getting back in during the winter?

I don;t understand...

You wouldn't want the air vented into the attic, but you could vent it through the attic w/ a vent on the roof. Is the bathroom on an outside wall? If so, just vent it out on that side.

It is ok to vent it into the attic only if the attic has good ventilation. I am in the middle of remodelling a 1903 house and the attic has no ventilation at all.
We had to vent it out the side of the house using a flap exhaust. It works well, but the house has a framed flapper exhaust on the exterior (eye sore).

If the bathroom vent is fairly close to an outside vent in the attic, it will be alright.

We have one and it's vented right to a roof vent via flexible aluminum duct. I don't see a good reason not to vent it outside. If not, you are just moving the moisture into another area. If you have poor ventilation up there you could end up with a mold issue.

EDIT: And that isn't an old house!

It'll vent moisture also so I don't think having it vent into your attic is a good idea, maybe through your attic and out the roof is what they meant?

As others said, if your attic is well ventilated, it isn't an issue. If not, then I'd recommend you vent it to the exterior. Does your attic have an exhaust fan of it's own?

Whats that smell coming from the attic?

get a vent AND a sloar light installed at the same time.

No vent at all is better than venting into the attic.
You need a new contractor as well, he's giving you bad advice. If this fellow has already done work on your home, make sure he's pulled a building permit. I've cleaned up a few projects where the contractor told the owner a permit wasn't necessary, it's often a great way to get away with doing substandard work.

usually those are vented outside

The house I rent had exhaust fans from the 2 upstairs bathrooms installed last year... both vent to the attic, doesn't seem to cause any problems.

(of course this is a rental so i dont really care what the landlord does as long as the place is livable - if it were my house they would be venting to the outdoors)

It will often work, but it's not the right way to do the job, and if your paying someone to work on your home, why pay them to do it the wrong way?

That's the way mine is. Seems to work OK.

we vent both of our bathrooms into the attic.

however our attics have ridge vents, and side vents to allow ventilation.
