No Window In Bathrooms

[fruitsalad]

How do these work? would they not smell if you can't open a window to let a bit of fresh air in

[naomi24]

Most have an extractor fan to the outside.  You often find bathrooms in hotels have no windows.

I don't have a window in my bathroom.  I have an extractor fan - you have to have one or the other.

This particular bathroom has no external walls it's inbetween 2 bedrooms then on the other wall it's joined to the neighbour, so where would the extractor fan be.

[naomi24]

Most hotel bathrooms aren't on an outside wall.  I guess the piping for the extractors is channeled along spaces between floors/roofs to the outside.  The builder might come along later.  He'll know for sure.

[Impatiens]

In our similar bathroom there's a ceiling extractor fan which is vented over the living room ceiling to the nearest available outer wall.

[The Builder]

Yes, for any room that's in the middle of a building and remote from an outside wall, the extraction is ducted. Just a simple 100mm pipe or flexible duct.

It can be taken through floor joists, but more commonly it's carried through the room(s) at ceiling height and boxed in.

There was a time years ago when Building Regs insisted on yer actual daylight in every habitable room. That was changed when they realised it wasn't necessary.

Providing they adhere to Part F there shouldnt be a problem.

My next question would be, do these extractors work well, and are they left on 24/7 or just while using the bathroom?  Thanks all for your help

Most extractors come on when the light is turned on. Some might have seperate switch

[ladybirder]

Mine has a seperate switch which I turn off at night as the noise annoys me.  That's because I go several times and it does run for quite a while each time.

[pastafreak]

I'm on the upper 2 floors of a small block of maisonettes. No window, separate bath and loo. Extractor fans are in the roof. Mine wasn't working for a while, but there was no odour. 

[The Builder]

Usually connected to the light so that you can't 'forget' to switch it on. Some have a humidity sensor so it comes on automatically when there's any steam about.

It's common for them to feature an 'overrun'. That means it will continue to extract for a while even after you've switched off the light. Can be twiddled to overrun from a few seconds to several minutes.

[ladybirder]

The most annoying thing about mine is that it is placed way above the bathroom door, a fraction from the ceiling.  Must have been a tall idiot who put it there.  I have to bash it with my walking stick.

[Atheist]

ladybirder, why do you have to bash it?

[The Builder]

Atheist.... I would guess LB is whacking the (compulsory) isolator switch.

If it is LB, then it's really intended to isolate the fan if it needs to be worked on.  It's supposed to be out of reach to stop people messing with it   😁

[Atheist]

Maybe it doesn't turn itself on, or off, when lb wants it to.

The Venting Fans Join Together To An OutPut Vent, Which Vents Through The Roof, or near the roof.  See, vents in buildings, even homes...are meant to move air or sewer gasses (also venting outside of buildings) in one direction. Your heater vent blows warm air, it doesn't have a fan that sucks air up into it..does it?        Try watching some 'This Old House' with Bob Villa. It used to be on PBS in the USA. He's a good explainer.
