    Redesigning plumbing for 2 bathrooms directly above each other in house
    From referencing the 2014 code and appendix N with examples, some plumbing setups that used to not be allowed, are now allowed, or so it appears.

    Please see attached diagram of my new plumbing setup plan.
    Will there be any code issues or problems with this?

    Thanks

    Does your local code allow wet venting, that is basically all you have?

    Yes, code allows it as far as i know, ive talked to a local plumber, but there is confusion with the new code change. I'm in Miami, FL. There cant be any offsets in the wetvent, but I don't have any. Just a vertical 3in pipe.
    There used to be a lot of effort made to put the sink and shower into the same 2in line before it entered the 3in line with the water closet.
    But now the 2014 code seems to not care about that anymore.

    ive noticed normally there is a vent upstream of any sink (or fixture with a trap) before it enters the 3in line with a wc. the concern as i understood was that a large volume of water going through (toilet flush) would suction the water out of the shower trap or sink/bidet traps.
    so i was worried about my upstairs bidet, since it would have a trap and no upstream vent before connecting to 3in line with wc. and the the shower also connects directly into 3in line with wc upstream.

    I don't do full house installs, typically replace and repair although what I have done has always passed. Last house I built in the GA mountains, I subbed DWV to be safe. I'm sure one of our licensed plumbers will help you out.
