I'm having an extractor fan fitted high on the wall above the bath. It is at the opposite end of the bath to the shower.
I am looking at the low voltage extractor fans, and having the transformer in the loft connected to the light switch - with the intention of it coming on with the light and the remaining on for a couple of minutes after the light goes off.
I have seen a few SELV extractor fans on screwfix and ebay. Most of the ones I like are IP44. Will this be enough?
I've also seen IPX4 - no idea what this means...
Any advice appreiated.
