Lots of options for fans out there... understand the low sones thingy (nobody wants to listen to a whiny fan).
I would shop the fan some more... you will find what you want.
Note: when mounting it... might want to work on the baffle... A backdraft of cold air is not what one wants to greet in the morning shower...

Your comfort, Your way, Everyday!
GA's basic rules of home heating and AC upgrades:
*Installation is more important than the brand of equipment
*The duct system keeps the house comfortable; the equipment only heats and cools (and dehumidifies)
*The value of comfort, over the long term; leave economic choices behind!
Choose your contractor wisely!
