There seems to be a lack of replies, no idea why. I posted a question earlier, I got zero replies as well!
Anyway, given you have had no response from anyone else, here's my input, if nothing else it may motivate others to chip in (or not).
Location
The standard 'zone' stuff applies. Here is a link to one of many sites that discuss the IP rating you need and other detail to follow regarding a particular zone. http://www.ctm.co.uk/extractor_fan.htm.
About Fans
If possible I would fit an 'in line' fan in a loft space etc via ducting. This is generally going to give you much better extraction than the 'through-the-wall' type fan approach. Make sure you fit a decent quality one - Vent axia are reasonable.
Make sure you AT LEAST meet building regs on the ventilation but remember than the extraction rates needed to meet regs are well below what is actually needed in practice, particularly in bathrooms etc.
Location of extraction point and inlet point
Make sure you locate the extraction point and air inlet points sensibly. You want to make sure that you pull air across the whole room with IDEALLY the extract point near to the point of maximum moisture (e.g. shower).
Ducts
Use large round solid ducts. Site the fan near to the extract point. Put a small slope on the pipe from the fan outlet going ouside to ensure any condensed water runs away from the fan. Traps can be fitted if slope can't be achieved. Insulate the ducting to keep the air warm until it reaches the outside to avoid condensing inside th pipe.
Fit a humidistat and timer.
Finally, make sure the room is kept warm.

You can put an IPX4 item virtually anywhere you want (except in the bath or shower tray - zone 0) where it will not be exposed to water jets, when it must be IPX5.

Soffit - the end of the word will probably be too far.
Some people have to go out work, you know.
