hi, could anyone help me with this one, is the ceiling above a bath or shower classed as zone 1 or an outside zone if it is more than 2.25 metres high. Looking at the on site guide, it seems to be outside zone 1.. But I had a look at an article in a trade mag and it states that the zone 1 above a bath or shower extends to the ceiling if the ceiling is less than 3 metres high. Which one is right ? and if zone 1 does not extend to the ceiling, and stops at 2.25 metres, does that mean that it would be ok to fit downlighters above a bath that are not ipx4 rated? Not that i would, its just a theoretical question.cheers
