I have installed bathroom mirror cabinets before where the isolator is not even on the same floor, but on a floor above and somewhere you'd not expect it - the layout of the house and what could be accessed dictated this. They could even be plugged in somewhere rather than hard-wired. So make sure you check every isolator/FCU/RCD/loose plug that you can find. While possible that both have failed, I'd say that is less likely.
