If you were fitting out your bathroom would you fit an extract fan
connected to a humidity sensor?

The bathroom has a large window.

I guess it's nice when you step out the shower to have it humid but
say 5-20 mins after a shower it's not so nice to goto the loo when the
bathroom is wet.

Perhaps a fan would work slowly so its still humid as you get out the
shower but after 5-20 min the place is de-himidiified?

Would a de-humidifier be more cost effective than a fan after all I
guess I have to heat the air that replaces the stuff that gets blown
out....

De-humidifiers are very expensive (the good ones) and you will have to wire
the machine in safely, for obvious reasons. The most cost effective method,
is an extracor fan, with a built-in timer. Ours switches off after 20 mins.
I bought one of those Envirolight hygromers, new on ebay, which uses a AA
battery http://tinyurl.com/2hwwze that confirms when humidity levels are
almost back to normal.

The most important consideration, if installing an extractor, is that you
have an opening or vent, which allows a similar volume of air into the
bathroom, to that which is being extracted out - otherwise the extractor is
none too efficient.
