I think you can get an adaptor that will connect the 4" to the 3". It
will make the fan a little louder than it should be, but if you buy a
good quality quiet fan it will be a lot quieter than the cheap one
you have now. Have you checked out the Panasonice "Whisper" fans?
They're the wuietest (and most energy efficient) on the market.
They're expensive, but good. Good luck.



bath exhaust fans are a bad idea anyway for a home...

Not sure I can buy into that one.


in the winter they draw heated moist air outside,,,,instead... after
your shower, just open the inside door and keep that warm moist air in
your house..

While higher humidity can make it feel warmer, that moisture in a tightly
insulated house can raise hell in various ways. In cold climates it can
contribute quite a bit to icing windows.


in the summer, open a window...

if your using central AC in the summer, you are still better off
closing the AC vent in the bath and opening the window...
