bathroom extractor fan, can anyone advise?

Hi all,

We are having our bathroom re tiled and we thought as we are at it we may as well replace the normal wall vent with an extractor fan.

But I know nothing!!

Its a small bathroom and we have an over bath shower. It will be on an outside wall opposite a door.

What do I need to be looking for?

Any 100mm fan will be sufficient.

Ideally, it should be humidistat controlled in addition to manual control, so it can come on by itself as necessary

Give some thought to the fans db rating, as some cheaper ones can be annoyingly noisy

The fan will probably have its own back-draught shutter, but also fit a shrouded extract hoof on the outside if that particular wall gets the prevailing wind

It is also best to keep the wall vent or fit a window trickle vent to maintain constant background ventilation

Get an electrician to fit it.
Bathroom needs to be part P, and if it's close to or over the bath needs to be low voltage.

I always tend to spec the Airflow Icon fans, maybe a bit more pricey than most but they are quiet, nothing worse than trying to have a relaxing bath while the fan is driving you crazy. These fans come as a basic model then you add modules to them to turn them in to the type you want i.e. Timer/Humidi/PIR....

All fans have different extract rates and some of the cheap ones have the capacity of an asthmatic hamster. And of course just putting in any 100mm fan doesnt mean it will suit the size of the room you have.

You need to calculate to volume of the room then the required air changes according to building regs.

Ditto, big fan of the Icon range - install a lot of these.

These guys always seem to do really good quality household stuff, I have one of these extractor fans in my bathroom. Google household2u - if you ring them they're really helpful as well.
