Clarification of ceiling fan position in bathroom

[balcock]

I'm in the process of planning a re-wire of my house (going down the notification route and doing it myself). I'd like to get some clarification on what zone my bathroom fan is actually in at present.

Only considering the bath it would be in zone 2. However there is a shower in the bath attached to a hose as opposed to being a fixed shower. Does the vertical position or furthest reach of the shower head play any part in determining the actual zones.

Yellow dots - spot lights 230v 50w - zone >=3<br>Green square - proposed IPx4 rated ceiling...

Notes on the diagram:
Blue dot is the approximate normal position of the shower head
Green square is the approximate location of ceiling fan (IPx4 rated)
Red shading shows area within 1.2m of shower head - its not intended to mean zone 1, I know thats the whole bath.

If the fan is not ok in this position I guess replacing it with an in-line fan would be acceptable?

Thanks
Barry.

what is the ceiling height?

In-line or SELV either would be ok..

apparently the area above the bath to a height of 2.25M from the bottom of the bath is zone 1..

zone 2 extends horizontaly 600mm from the edge of zone 1.. and up to a height of 2.25M

 

[balcock]

Near enough 2.4m. Its about 2.37m high. The decorative plastic cover of the fan protrudes about 10-15mm. The existing fan is mains voltage.

 

[ColJack]

an inline fan suitably mounted on AV mounts and such will likely be quieter for those middle of the night trips that occur as you get older..

Just out of interest, should the 2.25 Metre height of zone 1 be measured from the floor, or the bottom of the bath, which could be, say, 0.2M above the floor?

Strangely it is measured from the floor.

 

[ColJack]

it's coblers anyway.. I'm 6 foot 4 so my arms reach from floor level is way above 2.25M... it also means I have a 6 foot 4 arm span ( your arm span is supposed to be the same as your height JOOI )

 

[Taylortwocities]

Does that make you the missing link then, Jack??

 

[ColJack]

fingertip to fingertip,, not each arm...

coljack, you would have made a good plasterer

With that ceiling height your fan is out of zones so dont worry. I'd still replace it with a decent axial in-line fan in the loft space anyway, assuming the existing fan is a weedy little radial.

Wouldn't make any difference even if it was zone 1 - there is no requirement for fans to be SELV if located in zone 1.

 

[balcock]

Thanks for the advice. When the time comes I'll replace it with in an inline fan in the loft.

Are you casting aspersions on his protate?

 

[ColJack]

you're jumping to conclusions that balcock is a man....

and no I wasn't casting anything at the OP's protrate.. it's just the facts.. as you get older you tend to need to pee in the middle of the night.. especially when several pints of beer are involved...
