Here's the floor minus the tile with the first shot at patching/leveling and before using adhesive dissolver to get up the old glue ...
... next step is going to be doing caulking around the tub and toilet and water sealing ... plus another shot at the filler (the white area here) ... probably won't bother you with a pic of those ... then doing the adhesive remover, and a bit of sanding followed by a nice layer of leveling compound.
As noted in the previous picture, I pre-cut all the tiles, so once the surface is good-to-go this should be pretty fast.
