Basement Bathroom Plumbing Help

[ng6172]

Hey everyone, I am in the process of renovating my basement and im planning on making changes to the layout of the bathroom. The previous bathroom fixtures do not appear to be vented and i would like to make sure that the new layout is properly vented. Are there any problems that catch your attention with the drawing? Would a single 2 inch wet vent in this layout be sufficient? I will be tying into a 4 inch cast iron sewer line. Planning on 2" pvc for the lav/vent, 3" for the toilet and 2" for the shower.

Thanks

The shower in your drawing is not vented. Hopefully there is a shower wall along the drain where you can vent it. If not, you will have to route the drain line such that you can vent is vertically, or no more than 45 degrees off vertical, where the vent ties into the shower drain line.

And it could just be your drawing, but the drain connection for the sink appears to be a combo fitting, but that needs to be a Sanitary tee for sure.
