Bathroom Receptacle is out…wait a minute. So is the other bathroom. You looked at all the circuit breakers and they look ok.
It is possibly a GFCI receptacle that tripped.
Check around and see if you have a receptacle with a test and reset button on it. Simply press in the rest button and you should have power back on. If the receptacle trips out again, you possibly have something plugged in that is going bad or is bad.
These receptacles keep people from getting shocked, and are in bathrooms, kitchens, garages, exterior outlets and unfinished basements. So check there first before incurring a service charge.
They also make GFCI circuit breakers that do the same thing and protect the same areas.
