> Really?! Have you read 701?
If we assume the OP is a normal mortal shuffling sideways into a micro-bathroom, and not a plumbing contractor or Fellow of the IET who can afford to live in houses with bathrooms five or six metres across, then I think my position reflects the basic reality of why 701 (..702, 703) runs to several pages and why thousands of pages are written about this subject in books and on websites.
If that assumption is wrong then fine. He can stick a couple of two-pin adaptors into a spare 13A twin socket next to his 75-inch LED TV screen and washing machine and tumble dryer on the far wall of the bathroom seven metres from the bath.
