I am intending to install a new tub in my downstairs bath. It has a large linen closet that we do not use and would like to put the tub there. I am curious if anyone has ideas as to how to plumb this. I have my own, however I am not a plumber and would like to see how you guys might go about it. Keep in mind that the basement is half a floor lower than where the bath is. It is a tri-lvel house. I drew the floor plan, below, to the best of my memory and abilities. If there are any questions please ask as I intend to start on it this weekend after my wife leaves for CA for a little bit. Thank you in advance.

You haven't told me anything. Where will the tub drain connect to? How will it be vented. Back into the washer vent? Give me more details. Thanks, Tom
