I have seen people use extension cords in bathrooms too, mostly to plug in electric heaters. My mother told me water and electricity don’t mix, she also told me not to use heaters with extension cords but a lot of people don’t seem to understand that.
Remember the UK guy in his bathtub?
I think the UK building/electrical code does not allow for outlets in shower/bath room (versus the loo).
He ran an extension cord so he could use his iPhone while it was charging, while he was soaking. The UK uses 240V, and the charger/extension cord somehow managed to drop into the tub.
I’m guessing that he also neglected to plug the extension into a GFI outlet.
There was an article of a young girl that was listening to music on her phone while in the bathtub. Plugged into an extension cord - with the connection resting on the floor.
She stepped out of the tub and with her wet feet and the humidity in the bathroom with the cold floor there was enough condensation on the floor to conduct the electricity and she was electrocuted.
I turn on the bathroom fan switch using a towel when it is humid after a shower. Not sure if that does much - but it couldn’t hurt.
