I am just re-doing my bathroom out and would like some advice on the type of lighting to put in. I would like to put approx 4 low voltage spot lights in - however is this wise in a humid bathroom (I will be having an electric shower and am planning on installing an extractor fan). WOuld they need to be of a suitable IP rating? Also my loft is boarded out - do these lights need ventilation around them ? (the boards would come up for fitting but then go back afterwards - but would the insulation prove to be a fire hazard?)
