Toilet done! Doesn't necessarily look like it needed an overhaul from the pictures but the toilet itself was really bad, the walls were all damaged, the dry-wall on the right was moldy at the base because it touched the floor, etc. Was hoping to actually break it and leave it open to gain a few centimeters on the width of the room but there were too many pipes in all directions behind it, would have looked stupid so I rebuilt it brand new.
