Plumbing a Garage Bathroom (Cement Slab)

[EdNC]

I'm planning on doing the rough in plumbing for my small bathroom in my garage. Is this the right way to run the drain (black) & vent (blue) pipes. Do I need the vent pipe between the shower and toilet? If I put an additional floor drain after the sink, do I need another vent pipe in between the sink and the floor drain. Thank you.

Yes, the shower gets vented and also the lav.
Ideally a floor drain would get vented too.

Thanks Terry. If I moved the sink in between the shower and toilet will one dry vent work. for this setup. Thanks again for the help.
