it makes a big difference. Quite a lot of people call the room with just a toilet and sink in it a “bathroom”. And the electrical regulations for that room are very different for the room that has a toilet, sink and bath or shower.
That’s why we kept asking for clarification.
Your any socket in your room needs the isolating transformer or to be placed more than 2.5metres from the edge of the shower and/or bath. It doesn’t matter if it’s a regular uk socket, or a European one, etc.
There’s no wiggle room on that.
