    Standard distances?
    Is there a standard distance for placement of center of water closet drain to finished wall? I'm roughing in sewer plumbing in basement for future build-out before slab is poured.

    ... 12" from the wall but might want to check with the manufacturer for the recommendations.

    That's 12" from the wall to the center of the closet bend. This is standard unless you have a special order 10" rough in closet. Good luck, Tom

    12" is good news!
    Hey that's good news! I saw in some book that 18" was recommended, but that was AFTER (of course) I glued my closet bend together. My measurement is just about 13" from the back wall to the center of the flange, and I was worried that I'd need to cut it out and bust more concrete out and do it further out.

    I think that book may have been screwy though. On another page in that section they had some "standard" bathroom layouts drawn, and in one spot they had two in-line 18" measures, then a full-length measure of the same two points labeled 48"! Interesting math.

    Anyway, I'll keep mine how it is. Thanks!

    Not having seen the book I would hazard a guess as to where the 18" came from. 18" is the measurement for the lavatory stub out back to the floor.
    A 13" toilet rough's acceptable so complete your job. Good luck, Tom
