wet vent situation???

Author: RBM (NY)

hello,
Looking for some help from all the real plumbing experts on this board. I'm planning a bathroom remodel that involves moving most of the fixtures and therefore a new pluming layout. I think I have a possible wet vent solution, but I'm really not sure. Specifically, I'm wondering if I really need the shower vent shown in green on my drawing, or if I'm ok without it. I've tried to provide pipe diameters and distances to help explain the whole picture, but feel free to ask for additional info if necessary.
Thanks in advance for all the help.

you have the concept but i don't like the way the toilet is vented. there should be a long sweep 90 where the toilet turns and then put a 3 x 2 'Y' for the shower and lav.
aim that 'Y' to pick up the shower and using a full size 2 inch 'Y' pick up the lavs.

ignore the size of the tub drain as yours will be 2 inch for a shower.
this is not the way yours is laid out but the idea is to vent using "Y's". rolled up if possible
your extra vent for the shower is not needed.

Hey Packy, Thanks for the advice
Author: RBM (NY) Hey Packy, Thanks for the advice on the toilet. It is necessary to tie in the shower drain to the lav drain? Due to the joist layout, this would involve a lot more cutting and bracing. Is it problematic to run the shower drain separately from the lav? Would this change your previous comment that the green shower vent is not necessary? Thanks Edited 1 times.
