I wanted to attach an image to show what issue I have. The only way I could figure out how to do it is to start a new post. I appreciate all that commented on my drawing on my previous post and I realize now that it would not work because a portion of the vent would be horizontal below the floor. The issue is, the wall of the bathroom is over the joist and as the image shows, the vent was installed into the room and 45s were used to get the vent to the center of the wall. One of the 45s is visible inside the room next to the wall. Is there a way to do this so the vent does not have to go into the room?
