Where is the best place to vent a bathroom fan?

Question

I have a brick ranch with an attic that runs the full length of the house. Do I even need to vent it outside or is it ok in the attic? I would think mold would become a problem in the attic. . .?

Answer 1

If the attic is well vented it shouldn't be a problem. However many attics are not that well vented so just to be safe take it to the outside.

Answer 2

Out a side wall in the attic is best.

Answer 3

It must be vented outside. It doesn't matter how well ventilated the attic is, it will cause problems.

Answer 4

By code, you're supposed to vent it all the way out through the roof. Or, you could put a 90-degree elbow on the vent pipe and vent it out the side of the house. But, don't just vent it into the attic. This may cause a moisture problem and will make your attic kind of stinky from time to time.

Answer 5

Outside
