All the rooms in the house have electricity, but the bathroom has no electricity, and it is not bright, and the bolt has no electricity for advice.

Check the indoor distribution box. Your bathroom should be controlled by a circuit breaker.

If there is a trip, give it a try. When you push it, it will trip immediately, indicating that there is a short circuit problem in the toilet circuit;

If there is no trip, try using an electric probe. Are all terminals under the circuit breaker energized? If all terminals are energized, the wire leading to the toilet circuit is open. If there is no electricity at the bottom and electricity at the top of an individual circuit breaker, it is estimated that the circuit breaker is damaged and the switch needs to be replaced.

220 volts is dangerous. If you are not familiar with it, I suggest you find an electrician to operate it. Cherish life and don't take risks.
