Want to install a vent in the wall of a skylight over a shower. Having problems with condensation in the well. Would like to use one with a built-in humidistat (Broan makes one) but am leary about installing vertical. Anyone know if installing a bath fan in a wall when not recommended by the manufacturer is a bad thing? Other suggestions would be appreciated also.

They do make vent fans designed for wall mount.
All the ones I have encountered so far for wall mount are the $30 cheapo's and the 5+ sone thru wall monsters, neither of which have the built-in humidistat.
I don't recall brand but I did that. I called tech service for approval. The encouraging thing was that the rep knew enough to point out that the depth was too much for a 2"X4" wall so I felt she had some credibility. I think she said the fan might be a little louder but that may have had to do with being in a shaft not the vertical install.
Smile. It could be worse. You could be me working for you.
There is a outer piece, a hood that isn't shown. Very quiet, no humidistat supplied with them.
Well shti, there was a picture here when I posted it.
Panasonic makes a through wall small quiet fan. 70CFM, you can't hear it run. No humidistat, no switch at all. You're on your own there.

Is there an exhaust fan in the bathroom already? If so, then adding a small one to the skylight well is an OK idea. If there is no existing exhaust fan, then the small 70 cfm fan mentioned already is better than no fan at all. But, exhaust fans should be sized to the volume of the room.
Many of Panasonic's fans are rated for continuous running and many are also very quiet. On their website FAQ's, they do say that their fans can be mounted vertically altho the bearings may experience a shorter life span.
Panasonic's site shows how to size the fan based on the volume of the room being served.
When you install this new fan, where will the air come FROM that you are exhausting? If you have a very tight house you do not want the air to be sucked from the chimney or exhaust of any combustion appliance (boiler, water heater, etc). CO (carbon monoxide) poisoning is a life ending scenario.
