Agreed, years ago I pointed that one out to IEE as it was then. I suggested that if I had a bath on extended legs (not impossible) then heights for zones should be referenced from bath floor level rather than the floor the bath was sat on. But my point was not taken and room floor level won.
PS if a fan is mounted on or below the ceiling then the height is to the bit of fan you can touch, not the ceiling its mounted under I would think
I think that a plastic cased ceiling mounted extractor fan poses a very slight shock risk. The live parts are buried deep inside the fan casing and can't be touched. The fans are designed to extract steamy air. If the fan was all metal, and the user was standing in an earthed metal bath and the user touched the fan casing, and the fan casing was live, and the fan was not R.C.D. protected, then the risks may be high. But in reality baths these days are normally served by non conducting plastic pipes, and are made of non conducting materials, unlike years ago when baths may be made of cast iron and served by dodgy metal pipework. The regs. need updating to take modern changes into account. Modern shower trays are mostly non conducting and are safer.
