gonna probably have water intrusion issues around the tub, water will be in much larger quanities than mild tub spill over and there's nowhere for it to go except through the tile and onto floor
unlesss
>>2944485, but you'd have to run the curtain around the entire tub which is quite confining

will have to demo all that floor and wall to put a drain and valve there
the least invasive and best result would be to demo out that tub and it's frame. you will then have a drain and water lines exposed and available
you can build a new wall 60" off the left wall, run your water lines in there for a shower or tub/shower valve
then you can tile a pan with drain in current location
or you can move the drain for a tub drop in.
fiberglass insert walls would save you have to redo drywall with durarock and tile
so to summarize, easiest plan:
>demo existing
>build wall 60" off
>move water lines into wall for valve
>move drain for drop in tub location
>no floor repair necessary
>install fiberglass walls
>trim out, wa la
the exception to 'not repairing anything' is likely there's no tile under current tub, so there will be exposed concrete anywhere the new tub doesn't cover
