I would like to put in a in-the-wall medicine cabinet over a bathroom sink. A 3.5" OD PVC vent pipe rises through the center of the 2x4 wall behind the sink. Believe it vents multiple bathrooms. This bathroom is on top floor with a very short distance ceiling to roof.
Problem is how do I put in elbows when the pipe is the full thickness of the wall cavity? I expected to use 45 degree elbows to route around the new medicine cabinet space and back to meet the existing pipe at the ceiling. I could surface mount if I had to, but prefer a recessed medicine cabinet.
