This picture shows the current bathroom plumbing. The pipe on the left is the sink drain and has a vent pipe on the other side of the bathroom. The abs portion of the plumbing on the right is for the tub. Due to a few factors I need to move the partition wall the tub vent traveled in and move the toilet over a couple inches (yes, I know the joist is in the way).
My proposed layout is below. Any advice, critiques, or confirmation on design would be greatly appreciated. Is it possible to consider the main stack vent appropriate for the tub? The drawing is supposed to be the same point of view as the picture. Sorry for poor drawing!
