Bathroom Extraction (spotlight content)
Discussion
Hi learned folks. In the process of converting a small bathroom with separate toilet into one larger L shaped bathroom.
I want to put in decent ventilation (currently there is a window only). Above is the loft so I have the option of extracting via the ceiling and then venting in the eves. That's definitely my preferred route as I hate those wall mounted fan units.
My thought is that if I have ceiling ducts I can plumb them to an extractor fan in the loft area that is a little further away from the room so can keep noise down.
I notice that spot lamps are available with integrated duct around them. If I went for 3 of these in an L-shaped space that is approx 6m^2 and then plumbed them all to a single extractor fan, does that sound sensible? Or is there a better approach?
The other question is what I should use to operate them. I'm concerned that if I just use a timer off the light switch that it may not get used. It's a very bright south facing room so a lot of the time the light might be off. Is PIR a viable option?

Use a humidistat to turn it off. The main reason for having a fan is to get air flow and prevent damp. A humidistat is therefore what you want.
Extractor units that you are talking about are fine (inline units I think they are called).
The spots with extractors around them are OKish. I prefer the look of a well designed wall/ceiling mount one personally (I have Airflow Icons in my bathrooms).

One should be enough for an average bathroom. If you use a humidistat then it may only work for showers and not for smell removal. If you use the light switch you can just tell everyone to use the light when using the toilet or shower and the energy cost will not be much with LED lighting.
My loft mounted fan is controlled by a pir (which also drives the run-on function)

In this way, post curry disposal odours are vented without having to get the bathroom steamy.
Do take care to choose a quiet fan - I have a Manrose 4" mixflow, but it's only just acceptable on the noise level. I've fitted a tile vent and exhaust through that.

The extractor could be on for a week and my bloodhound Mrs would still complain. Which is why the bathrooms are all fully loaded with various air freshener things (and I am apparently banned from any of the "little rooms" in the house for 48hrs in advance of guests staying).
I'm not sure I've noticed any extractor really help with odour. But maybe that's just me
