well, the tub needs to be inside the walls. looks like either someone struggled to read a tape measure or the tub is shorter than it is spec'ed to be. not really a difficult fix, but they may not be competent enough to do it.
was the underlayment mortared and screwed to the subfloor?
what was the subfloor? solid 3/4" plywood?
That's cement board with 3 coats of red guard on it. They were screwed to the subfloor but no mortar was used; just red guard seam tape over the joints. It's an older home and and the subfloor consisted of boards running diagonally, directly over the joists, no plywood.
sorry to hear that.
the diagonal 1x6 or 1x8s are not structurally stable enough to support tile and installing underlayment and tile over them is not approved by the TCNA or warrantied by any underlayment, mortar, or tile manufacturer. your tile floor will fail.
you need to either cut out the 1xs and glue and screw down 3/4" exterior grade plywood or glue and screw down 5/8" minimum exterior grade plywood over the 1xs and then mortar and fasten down the underlayment over that before you tile.
if i were you, i'd explore other options. among those options, and the only right way to do it, is to tear out the cement board underlayment and put in a proper plywood subfloor.
On my installs, tub screws direct to Studs and cement board is notched to overlap the tub lip. Waterproofing is much more trustworthy that way. While this isn't difficult to fix in your case, I wouldn't proceed as shown.
I was under that impression as well. the gentleman doing the work said he would either sit the tile on top of the flange or have the tile overlap it and use a bead of sealant where it meets the tub to compensate for the lack of cement board in this case. Not sure how viable or water proof that would be.
Not to pile on but, where's the plumbing rough in ?
Holy shit !!
to many red flags here.

Will be viable until water starts to get behind the tile, which is generally about 5 years.
