This doesn't have to do with your situation, but according to 2018 IPC, can you not just wet vent the shower from the LAV as well. Did the 2018 IPC remove the requirement of the Lav being the last fixture in a wet vented area? I know yours is 2015, I'm just wondering about 2018 however.

Yeah I think I'm going to go this route. Than you very much for your help.

Thank you very much for all of your information! This is a single story house so it's definitely a vent stack. I just like to make extra sure what I'm doing is done properly.

It's a vent stack.

No it doesn't, it goes out the roof independently. But I did just go into the crawl space and the drain line from the lab is 1-1/2 instead of the 2 inch. I can change the wet vent part to 2 inch, but the dry vent part will still be 1-1/2 inch. Would this still be ok?

Thanks for the reply. That's the one I'm leaning towards because the current lav drain line is sloped incorrectly and that would allow me to fix that issue (been like that since before I bought the house). You don't see any issues?

Thanks for the reply. There is a lav in the bathroom. I've added a picture to indicate where it is. I've also labeled where there is a 3" dry vent that turns into a wet vent. If IPC doesn't have anything requiring the toilet being the last fixture downstream, could I just connect the tub off...

My next question is can the large 3in vent used for the old shower also serve as the wet vent for the new tub? I ask because I could potentially leave the old sink connected like it already is and just conned the new tub to where the 3" line for the toilet turns. Is it UPC that says the water...

Background: We are planning to make some extra room for the master bathroom and are planning to remove the existing tub/shower combo to install instead a stand-up shower with a separate claw foot tub. I have decided to model everything in 3D instead of trying to figure it out in the crawl space...
