I was hoping to get some feed back on a proposed bathroom layout and DWV. I've attached a sketch of the layout and an iso (you may have to rotate it to get the best view). Hopefully, it's not too much of a mess. The scale is not very good, but I just wanted to give you a rough idea. Basically, I wanted to back-vent everything except the guest shower in the common wall, then back vent the shower in the attic, then increase to a 3" pipe and vent through the roof. I wanted to do all of the vents in 2" so I don't have to mess with too many different pipe sizes. My main concerns are:
1. Is the double san-tee for the back-to-back guest lav and one of the master lavs the best way to do this?
2. Should the stack between the back-to-back lavs be 3" instead of 2". I don't think I have another 3" stack in the house and not enough elevation in the attic to put a 3" stack on the toilet and back vent the shower easily.
Thanks for looking at this.
