Bathrooms and electrics can safely mix, but only if it is all properly installed in the correct place. This is why UK rules refer to bathroom zones. It sounds technical, but really just means that the nearer to water something is located, the more stringent its rules are.
Zone 0: within the confines of the bath/shower
This is the wettest area (literally in water). This is restricted to very limited low-voltage equipment only.
Zone 1: directly above the bath or shower
Consider the area above the height of the bath or shower. Fittings in this area must be specified as suitable for wet areas because steam and splashes are common here.
Zone 2: the space adjoining your bath or shower
Please be aware: This is the splash zone around the bath/shower. You can add more choices here, but they must also come with the correct shield of protection rating.
Outside the zones: rest of bathroom
This is where you have the most flexibility, but as it’s still a damp room, quality fittings and safe installation are important. For an Electrician Cheltenham, visit dpalmerelectrical.co.uk/electrician-near-me/electrician-cheltenham/
What this means in real life
Sockets are typically located a safe distance away from the bath/shower (unless special shaver sockets).
Illumination and extractor need to fit the zone they are in.
Important that the feeder circuit is fitted with RCD protection.
The takeaway
If you’re renovating a bathroom, consider electrics during early planning – lighting, fan, mirror, and any electric shower. A qualified electrician can design it properly so that it stays safe, complies, and lasts for the future
