Hopefully it backs up to a bedroom closet or linen closet, where you can
easily cut in an access panel, thereby avoiding trashing the tile.

Oh, there's a bathroom closet, about two feet of open space behind the
shower wall. There are fixed (unmovable) shelves in there. The back
wall of the fixture side of the shower forms the side wall of the
closet.

So access is possible, sort of, but even if the closet shelves were
removed, it would be a gymnastic feat for a human to gain total
functional access to the area behind the shower wall.
