    Default I messed up - how to fix it?

    I'm doing a complete gut and remodel of my master bath, and trying to do as much work as I can. But sometimes it's just better to hire a pro. Which is what I did in this case. I had him install the drain and vent for a new tub. He put the drain exactly where I asked him to put it, but I messed up the measurements and now it is about 10" from where it needs to be. Now what?

    Can I put a couple of long sweep elbows to move it over? Or is this a cut it out and start over kind of problem?

    First of all, why glue the trap up before setting the tub?

    The fewer bends the better.
    After the last joist, use one 90 bend.
    Not two 90 bends like you have drawn in red.

    One 45 a couple of feet back in place of the double 90 sweeps would be better than the two 90 bends shown and still better than one 90 after the last joint. Around here a plumbing inspector would never allow a side bend without a drop. I always had to roll a couple of elbows.

    You already have a hole in the joist for the pipe, why make another? Just cut the trap off, install a long sweep 90, then use a new trap. One possible problem could be that the copper line, and 2x4, is going to be in the way of the trap's location. WHY was the dimension missed by such a large amount? Was it put where the overflow should be and you are trying to put the trap under the tub's outlet hole? A picture of the tub and the recess where it is going might be helpful.

    The 2x4 is the mount for a ceiling fan below. It would be a bit of a pain to redo, but could be done. Moving the supply line is the least of my worries, easily done if needed.

    Why was it missed Well I measured off of the drawings provided by the manufacturer to the drain hole instead of the overflow. (my mistake) Then when the tub was delivered it was obvious we had mis-measured how far we wanted it from the wall.

    The pictures show the tub where we DO want it. The tape measure is placed roughly where the center of the overflow would be. The piece of pipe with the yellow cap has not yet been glued in. Name:  tub2.jpg
