Advice on Bathroom Fan and Lights

[nabby68]

I would like some advice on the above please.

Regarding the fan not sure whether to get something that operates on humidity or motion. What are the pros and cons of both please? Does a fan with humidistat fitted just come on when humidity reaches a certain level annd then turn off when the room is cleared or does it come on as soon as it is switched on? Also any particular brands to choose or avoid.

Regarding the lights. I am having a shower niche in my walk in shower and wanted to have it lit. Are there any recommendations for led lights for this or any particular companies that supply this.

Many Thanks

Humidity fans don’t detect smells

As for lights, electricity and water - ask the spark on the job

In Europe many bathrooms and toilets do not have windows. They employ extractor fans are designed to be operated by the light switch and run a for a set time when the light is switched off.
I don't know what is available in the UK but if you go into any big DIY shop in Europe they are cheap as chips.

When on holiday never miss the opportunity to have a walk around these places and prepare to be shocked at the vast range of products available many of which never see the light of day over here.

Keep is simple, get an extractor with variable timed override, and a separate isolator

Would this need a switch to operate? So would mean an extra switch outside bathroom or only come on when lights are on?
Thanks

Fans can be wired to operate however you want.

You have to decide what you want.



P.S. Is Hampshire no longer in the UK?

Two switches should be enough if the three core is there for a timed override. The isolator is then wired in as an intermediate switch that allows light only. I assume a humistat works off the electronics in the fan wiring via the permanent live so won’t need a switch.

Yes, it triggers the timer circuitry for as long as the humidity is higher than the set value.

For clarity:

Well, it is in an intermediate position but is not what we mean by an 'intermediate switch'.

that allows light only.

Well, it just stops the fan working; it does not allow the light as such.

Thanks for all your replies. I think a humidistat operated fan might be preferable. Although a motion activated one has its benefits for getting rid of toilet smells
Regarding the LED lights for the shower niche, what type of switching for this is normal? Again, maybe PIR operated or a physical switch

In my upstairs bathroom, the fan is humidistat based. I did wire it so that I could flick a FCU if I wanted to get rid of smells. It works pretty well with regards to humidity.

The fan in the downstairs bathroom is an Icon 60 which has both a PIR and humidisat sensor. The IR is annoying if you only pop in for a pee though.

I went down that path because I figured that anyone showering during the day time would not turn on a light activated fan.

Thanks opps. Very informative as always
So your fan upstairs, you can use a switch outside the bathroom to activate it for unwanted smells?

A bit dodgy... but... I used a live from the ring. I ran it into a FCU with a 3amp fuse, I then branched it off so that have could have a perm live for the humidistat and a switched live for smells. I put the FCU and switch in a cupboard. And yes, I am aware that it is not up to regs, but it is my bathroom, and I will be the one that needs to make smells go away.
