Do I need an extractor fan in this bathroom?

[HappyHippyDad]

Hello all...

I have been asked if I need to fit an extractor fan in a small bathroom which has a window, which opens widely (cutomer would rather not have one if possible). It currently just has a toilet in it and a shower is about to be fitted.

I have read many of the threads on this subject but there seems to be a lot of different advice.

1. It seems it has to meet Part F and have a continuous extraction rate of 8L/S and intermittant of 15L/S, how would I judge if the window is acceptable?

2. Also if a new build or converting an existing room into a bathroom you would HAVE to have one, this room has a toilet and sink in it and nothing else so perhaps it is already classed as a bathroom??

Its just the 2 points above on I'm a bit stuck with??

Any advice greatly accepted :smiley2:

Its an existing house MDJ, but regs say if converting an existing room into a bathroom you need to have a fan. This room already had a toilet and a shower is now going to be fitted so is it already a bathroom?? :confused5:

Surely if it only has a toilet then its a "bog" and adding a shower will make it a shower room/bathroom.

if no shower, no need for fan.

If you are installing a shower in a room that currently has only a toilet and sink, then this is the conversion from sanitary accommodation to a wet room.
I.e. it was not a bathroom before but it will be after adding a shower.

The building regs part F say intermittent extract ventilation should be fitted in each wet room. Purge ventilation by window is only applicable to sanitary accommodation. (the area of the window (that opens) should be >1/20th of the room area.)

If the customer does not want a fan then get them to sign a form stating that they have refused compliance with the building regulations (this is given as a get out clause from Elecsa!), what the customer wants...

Thanks Richard, much appreciated.

To quote the elecrician's guide to the building regs.... "In wet rooms, purge ventillation can be provided by an openable window of any size."

To be perfectly honest, I think LBC should be more concerned with....

1) Joist sizes being halved by plumbers to lay central heating pipes...
2) Cables being indiscriminately derated by mountains of loft insulation...
3) DIY'ers doing what the hell they want...
4) Half the extractor fans in Britain being vented into the loft anyway....

before worrying too much if the wetroom gets a bit steamy.

I'm not disagreeing with you BUT a fan in a shower room does make sense.

I agree mate. HHD just asked if it was required, and imo if the customer wants to open a window, then that is all that's required on an existing property.

what about a wc with just a toilet and sink ,within an existing dwelling but the wc has been added i.e big room now has en suite

if it's no bath and no shower, no need for fan. opening window gets rid of methane as and when needed.

What do you think he has got in there a herd of cows?

Fans are building regs only nothing to do with wiring regs. A building inspector always 'recommends' fans. They cannot judge either way. It all comes down to owners preference.

That's the trouble with the nanny state. We get told when to blow steam out, how much insulation we must have, and how energy efficient our lighting must be...while all the time, the rich and powerful drive petrol-guzzling cars, get flown to conferences on private jets, and light up their buildings like christmas trees. Aint freedom great....

I have the same problem at the moment, currently rewiring a old house , the customer did not say they wanted a extract fan in the bathroom, so I didn't price for one and have installed an ip 65 bathroom fitting, when I had a nic inspection last year I had the same thing and the inspector didn't pull me on it, but after reading some off the other comments on here I'm presuming that if you are refurbing you should include one ? Building control are not involved with this job but is it still a regulation to include one ? I know it's good practise to put one in and I normally do but if they have said they don't want one then I'm not going to tell them they need one as it is existing and not new build
