Hey all, was hoping for some plumbing insight on my house I'm in the process of building. I've attached the layout of the master bath and was wondering if this would work/meet code/be the best way to do things. My main waste runs parallel with the basement wall directly below shower, so I thought would be easiest to run my 3" waste from the toilet, pick up the Lav waste from there, followed by the tub then the shower. If I ran a 2" vent stack for the lav, does that also serve as the vent for toilet since it's within 5' of each other? Also would the 3" stack at the end of the run serve as a "wet vent" of the tub and shower? Any suggestions would be much appreciated!
