Our Voltimum Experts answer your questions on a daily basis in our Technical Expertise area. This Question of the Day, concerning a non-fixed shower arrangement and zoning, is answered by the NICEIC:

My problem is with a fan locater over the shower, but above 2.25m height of Zone 1, it only becomes a problem because the shower head is not fixed.
Answer: You are correct in saying that any equipment installed in a shower area must be suitable for the zone it is installed in. Your fan is above Zone 1, but where water jets are likely [as when the shower head is not fixed], the equipment must have an IP rating of at least IPX5 (Regulation 701.512.2 refers).
It would also be prudent to use an SELV fan to further minimise any risk.
