Bathroom wiring is strictly a “no go” area for even the most experienced handyman / woman or DIY expert. Bathroom wiring MUST be undertaken by a licensed electrician. This is not only a legal requirement but it’s simply never a good idea to risk severe injury or death for the sake of not using a licensed professional.
Before reaching the final electrical wiring stage you will already know where your power points, lights, exhaust fan, heated towel rail, spa bath will be. If you haven’t already done so this is the time to buy any new items you intend to include in your bathroom renovation project. An online bathroom showroom is always the best place to find new ideas and inspiration for bathroom fittings, taps and furniture.
