Shower Plumbing
I am getting ready to plum a bathroom. Can someone with experience please vet my plumbing design. Does the sink need a vent also? Please ignore my lack of scale. The toilet is obviously way too high
Thanks!
Thanks!

One more question. Is this diagram acceptable. Here the 3 inch vent is shared by all. Or do I need another vent between the sink and the shower? This diagram is how the existing plumbing is.
Thanks!
Thanks!

The sink needs to have a sanitary tee and revent, what you have now is an S trap which is not allowed. The sink and shower drains cannot tee into the soil stack but must be connected with a wye.
There may be other faults but these I know are needed.

As mentioned, the sink needs a direct vent. The shower needs its own vent if it's more than 6' (I think) away from the vent (soil stack).
I would recommend redrawing or dry-fitting with pictures. There are certain cases where you can use Sanitary Tees and when you have to use Wyes. At least for me, that's the most complicated part... which I've gotten wrong a few times before.
