The zones in plain English
- Zone 0: inside the bath or shower tray itself
- Zone 1: directly above the bath or shower, up to a set height
- Zone 2: a band around zone 1 – the area most likely to get splashed
- Outside the zones: the rest of the room, though rules still apply
What can go where
Fittings in zones 0, 1 and 2 must have a suitable IP (ingress protection) rating for water, and some must run at extra-low voltage. That's why bathroom downlights near the shower are different from the ones in your hallway. Switches are normally outside the zones or operated by a pull cord.
Standard plug sockets are only allowed a good distance from the bath or shower – in most UK bathrooms that rules them out. A shaver socket near the basin is the usual solution.

Why bathroom work is notifiable
In England and Wales, most new electrical work within the zones is notifiable under Part P. It needs to be designed, tested and certified properly – another reason to use a registered electrician.
