Do they make a fitting that would allow the tub drain on one side of the joist (a hole then trough the joists) and the overflow on the otherside.

My Joists are TJ's so I can't notch them, hole has to be closer to center so the drian fitting "L" (tub shoe?) needs to be longer at the top before it turns.
IS there such a fitting, is it allowed?
OR, is is allowed to "T" the drain and overflow UNDER the joist?
Thanks,
Kevin

There are also waste and overflows that have the drain under the shoe if that is what you were asking...
 
drain

There could be more than one way to do your drain, but we would have to see a picture or drawing to tell for sure. The elbow under the tub is a fixed measurement, and they do not make them with different dimensions below the tub. There are tubs with raised bottoms so the drain is above the floor, and drains where the outlet drops down from the tub outlet, with a flexible hose for the overflow, but that might also need notching to get under the tub.
 
here is a drawing to show what I am trying to do.

I want the drain on one side of the joist and the overflow on the other. I can not notch the joist but I can drill a hole through the midde. BUT, is there a (shoe?) the drain that "L's" off to the overflow, that is longer on the top, like 3" before it turns to join the overflow.

Normally I use a plastic w & o, using a street 45 to offset the vertical from the top, and then angle the shoe drain over to the tee.
This way, I can move the p-trap over quite a bit.

In your case, the floor joists are running the other way, then yes, you could drill the TJI and go through the thin part of the joist to get to the tee.

We KNOW exactly WHAT you need, the problem is that NOBODY makes one, period. You have to work with what you can get and what you have to deal with. Even the flexible overflow will not help you if the tub is sitting on the joist with no room between the joist and tub.
