Just want to add to this.yeah, you can buy a cheap fart fan that fits in a tight space, but when it is used, sounds like a jet engine
or spend an extra 20 bucks, might have to get creative in the install
but it will be quiet
All fans sound good on display in the store, but they have no duct on them.
To much resistance in the duct and the fan chops the air that dosn't get out of the way fast enough. So pay attention to duct, 4" insulated as short as possible and as few bends as possible.
And enough space under door to allow air movement.
