I'll have my daughter ask...
In some jurisdictions, if the fixtures are merely replaced in the same location and connected to the original plumbing (within reason...replacing an old valve would be ok, for example) there may not be a permit required for the bathroom. Where I used to live was like that...I did not need a plumbing permit when I re-did the kitchen and powder room (and the original master bath upstairs) because it was merely a facelift with no new plumbing involved. But again, it's jurisdiction specific.
