I want to remodel my bathroom. The bathroom is 7’x9’. The sink, toilet, and shower are on the one 7’ wall which coincides with the wall the kitchen sink is on. All appear to be on the same vent stack apart from the shower. I want to move the shower and toilet over to the other wall. I was looking through the wi plumbing code and couldn’t find an answer on if I need another vent stack with moving the toilet there. I have an answer for other plumbing codes but Wisconsin apparently has to be difficult.
