Long time reader, first time poster. I'm converting a small upstairs bedroom to a small bathroom. The layout is pretty standard as seen in my hand draw masterpiece below. The toilet and sink are to the right of the entry, there will be a clawfoot tub to the left.
What makes this build unique is that this bathroom is on the second floor of an A-Frame home, so the vanity and toilet will be against a knee-wall on one sloping ceiling, and the tub will be against a knee-wall on the opposing sloping ceiling. I would like to wet vent this so I only have to drill one hole into the sloped ceiling.
The second drawing is my rough plan; is this acceptable for wet venting? Do I need a second vent coming up from the 3" section before it connects to the vertical section going downstairs (like in the 3rd image)? Also is there anyway I could avoid drilling through my ceiling entirely with an AAV? I'm in King County Washington for reference.
