Extent of Zone 2 in a bathroom - oval bath.

[pejoli]

Quick question on where zone 2 ends.

I have a rectangular bathroom 2.1 x 2.8 m. The bath will go across the shorter width. Next to it on the longer wall will be a sink (about 60cm wide), with a cabinet above and 'hotel' light fitting on top.

Looking at the regs diagrams, zone 2 is normally highlighted to extend 60 cm from where a rectangular bath meets the wall - this would put my cabinet light in zone 2.

But ... my bath is teardrop shape freestanding - it'll be 15 cm away from the wall with the sink on, and of course very rounded. The Bath taps are on on the centre line of the shorter width wall (though I guess that's neither here nor there).

So in this case, how is that zone 2 60 cm measured - is it from the light fitting to the closest point in the bath that will have water in it (on a plan view) - in which case I might be ok to use a non-zone 2 light, like the one I've already gone and bought .....

This came up a while back, about the location of a shaver socket IIRC, in this situation:-

My take is the 600mm should be measured from the outside edge of the tub, not the inside edge.

The intention of the zone is to keep electrical items out of reach of anyone standing in the bath, and any accidental splashes. I would consider the small area in the corner marked '?' should also be included in zone 2, as, although technically outside the 600mm limit, the only way to reach it is to stand in the bath, which is what the zone definition is trying to prevent people from doing.
