Downstairs toilet extractor fan

[Sputnik76]

I'm getting plans drawn at the moment for an extension to my house and the kitchen will include an internal room (with no window) that will be a small downstairs toilet and basin.

My question is whether I need to add in an extractor fan and if I did so then where should I extract to - as the room is inside another room (the kitchen).

1. Yes, you will need an extractor fan.
2. Extract to the exterior, you could fit a false ceiling in the toilet and run the extractor pipe above the kitchen cupboards.

Thanks Andy. The problem I have is that the toilet is against the party wall internally and opposite from the kitchen units. I'd have to vent over a distance of 3 or 4 metres - I suppose by putting a tube in the ceiling or something. Not ideal really as the ceiling is already plastered and I'd rather not tear that down.

Also depends if the joists are going the correct way. Or it means it being boxed in.

Floor is coming up and plumbing/waste etc will run underneath a solid floor - I guess the venting could go out that way?
