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:

If the customer wants a fan, send them a quote!

On new builds I'm under the impression that fans are mandatory

Just needs fitting.

Unless the customer was expecting one in the price he was quoted and a fan wasn't installed!

Insufficient info supplied to determine that, may have been the same problem with the customer as well assuming it would be done.

However, an opening window cannot be classed as continuous ventillation.

It's a toilet producing smells or sink or bath or shower capable of producing water vapour that causes the need for permanent ventillation.

Sorry, should have explained that the customer would rather NOT have one fitted unless has to (have edited post)

if there wasn't a fan before trhen you don't need to fit one. assuming it's not a new build. i spoke to BC last week regarding a shower room with a toilet in t. their exact words were " it's only the shower that must have a fan to extract moisture". they couldn't care less a bout the bog.

Thanks Tel,

At present it just has a toilet, they are now going to fit a shower?

Small rooom + shower = loads of moisture. Shut window and no fan = mould.

I'd be recommending a fan.

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

I think I agree, but the customer doesn't want one if he doesn't have to by law, hence needing to know the regs?

Telectrix! You're not reading my posts!!! :90:

Is it a new build buddy? or an existing house which is just having a shower fitted?

 

[Octopus]

If they don't want a fan just make sure they buy loads of bleach and are prepared to re-paint on a regular basis. Rather them than me.

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 has 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.

Its got 3 showers in it a sauna and 5 bath tubs!

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.

phew that was hard work

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
