Do those shower walls have any waterproofing? If you're going through all this hassle might as well do the walls so they aren't tearing it out in 10 years again
This was my point, but I'm not sure it was received/understood.
That shower only had the pan liner. You can see where tiles came off the wall it doesn't appear that there is either a sheet membrane (i.e. Schluter Kerdi) or a fluid-applied (Red Gard) waterproofing present. Going to all this trouble with the pan to still have no water proofing behind the tiles on the walls just ensures that the homeowner will get to do this exercise again in the future.
Tile is decorative, that's it. Any reliance on the tile or cement backer board for water proofing will fail eventually.
I don't mean to get ahead of the OP since the subfloor just went down, but IMO the same waterproofing needs will apply for the tile outside the shower (at the door, around the tub, etc.). If tile is just put down directly to the OSB sub floor or a cement backer board (attached to the OSB), water will eventually get to the OSB and rot it out again.
Not trying to throw stones at the OP as he seems interested in truly getting this repair done correctly, but it looks like the tear-out should have been much more extensive. If this was from the direction of the homeowner to try and save money, be sure to not warranty anything beyond a year, and get it in writing.
The tile guy will be doing the rest of the demo and going back with laticrete hydro ban for waterproofing under all new wall and floor tile.
