      I am replacing an existing shower-only with a whirlpool tub and the drain happens to line up directly over a floor joist. The house is 115 years old and the floor joists are about 12 deep spaced at 10-12 c/c (they dont build em like that anymore!), so I think that it will probably be ok to cut out a portion of the joist. It sure would be nice not to have to do that, though. Is there a way around it?

Is there a way around it?you always jack the tub up. what part of the drain are you referring to? you shouldnt have to notch over 2 deep and from what you describe, I cant see where that would hurt.

      Im not sure what you mean by jack the tub up. The tub will placed in a bed of cement for support, but this will raise the tub only about an inch or so. Is there something else I should do? I am referring to the part of the drain directly below the drain hole in the tub.: : I am replacing an existing shower-only with a whirlpool tub and the drain happens to line up directly over a floor joist.

      You only have to cut out enough so that the drain elbow will fit. You can then install the P-trap to the side of the joist and put an offset in the overflow pipe to connect to the tee.: I am replacing an existing shower-only with a whirlpool tub and the drain happens to line up directly over a floor joist.
