Installing new toilet downstairs - extractor

[Gavbo]

Hi - I've installed a new toilet and sink downstairs, under the staircase. The problem I have is there is no external wall to fit an extractor fan to. There is a small window, but it opens up directly into the garage, so not ideal.

So my question is, how do I install an extractor fan or could I just get away with the small window to the garage?

Many thanks in advance

Could you not put the fan into the wall with the garage, then duct through the garage to the outside?

Most cheap fans won’t be good enough for that btw

In line fan and a ducting kit, that way you can put the fan in the garage where it’s easier when it comes round to cleaning.
