Default bathroom venting into attic

Whats the general opinion on this. Ive been reading alot of conflicting opinions. Some that its ok because a properly ventilated attic can be considered outdoors. Some that it must be vented directly outside the attic space. Ideas?

Anybody that says it is ok to vent warm, moist air into the attic is an idiot.

Warm, moist air should be vented the the exterior and in cold climates can create considerable condensation in the attic when vented inside there. Insulated vent pipe from the fan to the exterior is best.

The idea should not even be considered.
Time to throughly go over ones education.
The understanding of ventilastion is critical in a homes overall health.

The purpose of attic ventilation is to rid it of moisture. To intentionally vent moisture into the attic space is absurd. Where in the world are you reading that bathrooms can be vented directly into attic space? Can you publish the links here, please?

Is venting fart fans into the attic within code?

I have no ventilation in My attic . I recently removed the roof vents and closed the Gable vents and when warm weather arrives I will finish closing the soffit vents .
I have sealed my home from the attic 17 inches of insulation attic access is well insulated and sealed

true 8 years is a while.. but i figured that fart vent technology hadnt changed much. Tha whole discussion had me scratching my head because both sides made some decent arguments lol thought id see what you guys thought since i figure bathroom venting directly outside was a no brainer till i read that.

Your education is probably more current. That thread was started almost 8 years ago.

Interior air entering the attic in cold climates? Here's what happens.

I got to see this just yesterday. The owner had removed the whole house fan louvered cover "four years ago"(his words). He had no idea.


Oh and the one photo is a stitched panorama, thus the few warped sections of the photo.

And don't let a contractor try to argue that stuffing the end of the bathroom exhaust pipe down into the eaves is good enough. Like Stephen said, anyone that says that is ok is also an idiot.

Everyone has bathroom venting through the attic photos.
It is a common occurrence.
Proper methods:
Venting out of the wall protrusion, or vented out the roof protrusion.
Lots to do.
Take you time. The best education " IS HERE!!" Free!!
Video tutorials. Everything know to man. HA HA HA Opps and women.
Almost forgot the gentler of the spices. MMM. They even smell good.
Pleasant to touch and snuggle up to. But have the scorn of a thousand scorpions. HA HA HA

I take it most of you don't approve. I see this at 75% of houses I inspect, homes listing price does not seem to matter.

First photo from today, and this attic had turbine roof vents (the worst).

Second from 2 months ago. This was the home of the builder of the development this house is located. He told me it was a stupid requirement to vent at exterior. Three baths vented at main attic, I couldn't locate huge master bath vent, it wasn't at the exterior.
