Tim had to pull the tub back into place while Anne guided it with the jack. Once we moved it as far as possible, Tim jumped over the tub and we pushed it into place.

If you look very, very carefully (click on the picture to zoom in), you can see the toilet supply valve on the right wall. It's hiding behind the tub on the very far lower-right corner of the tub (as we're looking at it in this picture).
