You Say Color, and I Say Colour

In the UK, AC power is 220 volts at 50 Hz, whereas the US is 110 at 60 Hz (here’s some explanation). In bathrooms, the power regulations are pretty complicated, and mean power outlets aren’t allowed within a certain distance of the tub and basin. But what about electric shavers? The solution was 110 volts, thus lower amperage. In recent years regulations have changed, and now allow for a 220 volt outlet in the bathroom, but only integrated into a mirror cabinet, like the photo shows.

Older regulations also meant the light switch had to be a certain height off the ground, meaning a lot of bathrooms have pull-cord switches.
