Like this a lot but if you use the four inch hose it will not be as quiet as the six inch

Unfortunately the half bath is on the first floor of a 2 story house and the exhaust duct installed was only 3 dia causing the xb50 fan to put out a lot more noise

If youre going to use a 6 pipe youll find that very difficult to do without destroying the pipe

There was no damper in the duct and when using either the heater or ac a lot of outside air got sucked down that duct into the house terribly inefficient

Enlarged the round hole to the required 11 x 12 square hole

This is because you have to bring the duct into the enclosure to attach it and it was way too hard for me to do this with a 6 duct
