Still working out a good punch line. I'm seeking any layout/design guidance. Photos and drawings attached and linked below. My objective is to reposition the tub against the right wall where you see it in the photos and install a shower in the open corner opposite the toilet. All drains need to tie into the vertical cast iron stack next to the toilet. How do I connect all 4 to the 4" cast iron stack? My plan is to remove the light blue cast iron above the floor and the wye that's there below the floor and tie in PVC with banded couplings - that gives me about 3/3.5 vertical feet to play with to tie things into. What's the preferred approach - stack wye for toilet first, with sanitary tee with 2 inlets for shower/tub and sink on top? Or, use something like this given space constraints: https://www.supplyhouse.com/Spears-P418-420-4-PVC-DWV-Sanitary-Tee-w-2-R-and-L-Side-Inlets.
Shower and Tub I can vent by tying into venting already there for 1st floor bathroom behind the knee wall. the toilet and sink are curently wet vented and work fina as is.
Would appreciate any advice, guidance and even a drawing to guide me.
