Hi. I am in the process of getting ready to plumb an existing faux marble shower (that I demolished last weekend and am down to the studs) that was in place. I am trying to decide how to run the pvc pipes for a series of shower heads. I have one shower head with the on/off valve. I also have 2 additional fixed shower heads and one hand held shower. I am in need of some tips of how to plan how/where to run the pvc pipes. I have worked with plumbing in my own home before. I have never designed a shower with a series of heads. Anyone out there that can help me? I can email someone a picture of where I am, but I cannot seem to paste it here. Holly
