How to install tub drain where toilet once set?

I am working on concrete slab. The only location for placement of tub is in location where toilet once set. The distance from the front of the tub to the opening in the floor where the toilet once set is greater than the tub drain. Can someone help me?

You will have to bust out the concrete. The problem is the toilet has no trap and the tub will require one. Break out enough concrete to access the existing toilet piping (3 or 4 inch) reduce down to inch and half (or 2) and install a trap for your tub. If you connect the tub to the existing toilet drain you will get sewer gas from the tub. It will stink and it is dangerous.

Thank you! I was hoping to keep from tearing up the concrete, but what you suggested makes sense. I appreciate the help!!
