Why not the attic if it's vented?

The exhaust fan in a bathroom is used to vent the moisture from a shower
also, not just the smell, so you'd be throwing vapors into an enclosed space
where it could turn into mold and mildew creating other issues. Stick with
Phish's idea of direct-to-outside venting.
