The IP rating for the light fittings that are to be mounted in the bathroom has to be high enough for them to be fitted there - see the permissible IP ratings for the bathroom lights. A ceiling-mounted pull-cord switch with the cord made of insulating material is the safest option for a bathroom. Standard wall-mounted light switches are a possible danger because of dampness and wet hands.Central heating is the safest way of keeping a bathroom warm. But if you have an electric room heater, it must be fixed at a safe distance from the bath or shower - it has to be outside of the reach of the splashing of water.
The electric and gas water heaters in a bathroom must be fixed and permanently wired, unless they are powered by a socket fitted three metres from a bath or shower. Electric heaters should preferably be controlled by a pull cord or a switch outside the bathroom.
Safely Installing ShowersAn electric shower must be supplied on its own circuit direct from the consumer unit.
Please Don't bring any mains-powered portable appliances such as hairdryers, heaters or radios into a bathroom. You could be severely injured or die. You can get a fixed hairdryer with hot air delivered through a flexible plastic pipe installed in bathrooms.These tips, along with other Electrical Safety Considerations for Home Appliances & Home usage - can be found on the Electrical Safety Council website. Remember: when you want to install the Bathroom Lights, the Bathroom Sockets or the Bathroom Heating Solutions / Hand Dryers, you have to keep in mind these simple rules and even better, consult an electrician.
