need help choosing a replacement ventilation fan

10 years ago

First, I have read the previous posts on this topic and found them very helpful. My question is a bit different.

I went to a big box and bought (sigh) a Broan 100 CFM heater/fan/light. Then I realized it needed a dedicated circuit, so now I'm rethinking my choice.

I'd like to select a Panasonic fan light combo. The current opening is 10 1/4 x 14. The fan is going in an existing bathroom, and I'd like to make the install as easy as possible. I'm paying someone to install this, and I'd like to choose a model that's easy to install in the existing space.

I'm also intrigued by the humidity/motion sensing models as it's a teenager's bathroom.

I have *no* idea how the ceiling joists are, but I do know that the current (dead) fan is vented to the outside.

I'm having trouble determining from the web how large the opening is for various fans - some seem to specify their opening; others not.

Any help would be *most* appreciated!
