Lighting and sockets are in the same circuit, which is the lighting of the bathroom and the lighting

OK. For example, table lamps and floor lamps are not all plugged into sockets. Because the light path does not need to be leaked (only zero live wire), and the socket is a zero three wires of fire ground, as long as your socket is connected to the leakage protection, the two conditions of use are fully met, so the light path can be the same circuit as the socket, but the socket can not be connected to the pure light path (no ground wire).

The regulations don't say no, but they are generally not designed that way.

First of all, if the lighting switch in the hallway is turned off, the bathroom socket will be out of power (because it is the same circuit) and secondly, it is not safe.

Toilet socket circuits are equipped with leakage protection, because there is a high possibility of short circuit and leakage.

If you are not a professional or do not understand the circuit situation, the judgment and operation of the light is not on may be fatal.

Yes, it is necessary to have a thick main wire, the lowest square, and the bathroom socket should be waterproof and equipped with leakage protection.

I don't know if your total switch belt comes with a leakage warranty? It is best to have a leak protection in the circuit of the socket, especially in the bathroom. It doesn't matter if the light and socket are in the same circuit, that is, your socket is protected by jumping, and the lights in the same circuit will also be extinguished together.
