    Default basement bath venting

    Could someone be so kind as to sketch on this image where they suggest i put vents?

    I seem to get conflicting advice whether one vent is enough or if each appliance (shower, lav, water closet) needs its own vent.

    thx

    One decent vent is all that is needed. They are sized in CFM's due to room size. Panasonic makes some excellent, very quiet fans

    from looking at your picture i would run the vent straight up behind the toilet then tie the sink and shower into that pipe in the wall above the high level water mark of the sink. looks pretty simple to me.

    no T's allowed on the drain side, only on the vent side. install the toilet drain with a wye to the sink upstream of the toilet and a wye to the shower downstream of the toilet. then the toilet vent goes up the wall behind the toilet with a T for the shower and sink vents up high on the wall above the high water line of the sink.
