Hi there,

I have a new bathroom studded out and can easily get below and above for plumbing lines. I'd like some advice on how to drain and vent the following:
toilet next to shower across from pedestal lav.

The main waste line for the house is located 4' down and to the right approx 15' (opposite the entrance to the bathroom). I am planning on running a new 2 1/2" PVC vent to the roof since I have a clear shot.

I think all the fixture vents can be vertical once they're above the flood height of the lav, right? The lav is what puzzles me. Will I have a long run of vent running 45 degrees through the wall?

See attached diagram.
