Currently adding a bathroom in the basement. I have read many forums on wet venting a bathroom group. I think this layout is a little different from most of the previous forums and diagrams. I am going to upload a couple sketches. I would appreciate the information on whether or not this would be considered a wet vent for the bathroom group or I would need to vent each fixture individually. I know it's a terrible quick scribble diagram but I think it does the job. The blue is the shower, brown is the toilet, and yellow would be the 2" vent/drain for the vanity. Thanks!
