Hi, I am an avid reader, but first time poster (just registered). I am building a shop with an apartment and finding a plumber is tough on an island, unless I want to wait 3 months or longer. In any case, the under slab rough in was done by a plumber before the concrete was poured, consists of a 3" stub for the toilet in the shop, vented by a 2" stack and a main 3" stack.
I have built several homes before and am not new to this, but before I go to down so to speak, here is my diagram as I envision it. I have already added another vent as shown in some diagrams/photos by @Terry
The one part that I am not 100% sure if I can use the 2" stack as a drain for the washing machine and the bathroom sink directly above on the second floor (they share a wall). The shower and toilet are at the opposite end of the bathroom. I will also feed the kitchen sink and DW into the 3" stack.
Here is my sketch.
