Apologies if this isn't the right section to post to, and apologies also for the length of this post.
I'm completely gutting our 3rd floor bathroom in our 1925 Victorian twin in Philadelphia. So far I've removed the old tub, old fiberglass shower stall, radiator, toilet, floor tile and the partition wall / framing and I am now getting into the actual workings of the bathroom which unfortunately is a bit of a state with multiple patch jobs done over many years.
Ultimately, I will have to do joist repair and sistering as the old work joists have been severely notched across several of them to install the shower and tub drains and the toilet. My plan is to completely remove the tub drain pipe as we are not replacing the tub and add a new tiled shower (KBRS pan) in that area so I would move the shower p trap to this area, shortening the distance between it and the vent as I believe it is too far away currently. The current shower p trap is further than 8 feet away from the vent which is on the other side of the wall behind the toilet. Also currently both the tub and shower drains are connected (pic 01) to the toilet waste but the connection to me seems to be only 1 1/2" connection so the 2" shower drain has been reduced down to 1 1/2".
Q1. Can I merely cut off the tub drain pipe at the yellow circled area and cap it?
Q2. If I add a new shower p trap and drain in the general vicinity of where the old tub drain is located (pic 03) will this properly vent the shower? Would I need to adjust the toilet waste pipe with a new fitting such as a combination wye instead of the current configuration.
Q3. If I need to change the configuration at the toilet what would be the optimal place to cut the pipe there - can any of it be salvaged?
I hope this made some sense and thank you for any assistance and guidance!
