I'm reading the IEE guide to building regs (version 16, part P, dated 2006)
prior to getting a new electric shower, the circuit upgraded, RCD fitted,
inspected, certified etc. but I have a query over positioning of light
switch and shower isolator before I start hacking even more tiles off,
fitting preparatory trunking etc.

The shower is in a cubicle quite near the main door to the room. Headroom
floor to ceiling is only 210cm near the door so if I put pull switches in a
natural place they are still within the 60cm rule for zone 2 so are
forbidden (unless I put them above ceiling and have a hole through).

However, is a plate type switch okay outside the door to the room even
though it is only 30cm from shower edge but via cubicle door and room door?

Regards
Phil
