Towel Rail

I'm not actually sure I understand the 'spirit of' (i.e. thinking behind) the position of the Zone 1/2 boundary - do you?

No - I don't understand why Zone 1 does not extend horizontally.

Exactly. I can but presume that they weren't thinking primarily about electric shock hazard. From that POV, I would have thought that anything touchable by someone (quite possibly wet, naked and standing/sitting in water) standing in a bath or shower tray should count as Zone 1 - i.e. I would probably have expected Zone 1 to have the current Zone 2 boundaries.

Kind Regards, John
