Zone 0 is inside the bathtub. Damn, so I can't put an outlet there? Zone 1 is over it, and zone 2 is 2 feet around it, and allows 12-volt outlets for small gadgets. Beyond that you can have ordinary outlets with the right circuit breakers (aka RCDs, GFCIs) integrated into them.
That's just not true. Electric toothbrushes, shavers, it's also not uncommon to have a washing machine in the bathroom.
Maybe the UK is doing something weird here, but bathroom outlets are very much common in the EU.
British standards are all BS. The electrical wiring one is BS7671. It divides the bathroom into zones: https://flameport.com/wiring_regulations/BS7671_selected_sub...
