So I finally finished installing my new bathroom fan. Worked on it only on weekends and a bit in the week here and there. Basically the fan is in the basement sucking air from a pipe leading up to the attic, then to the inlet in the bathroom. I could not vent in the soffit due to the attic/roof setup. Impossible to get close enough. Would of had to cut a hole in the roof to get to that part, and decided against that. I may need to maintain the fan in the future, I rather have it in an easily accessible area. Venting through the roof was also not recommended by a roofer I talked to, due to moisture buildup inside the pipe - does not matter how well it's insulated. Here's some pics of the process: http://gal.redsquirrel.me/?level=album&id=31 I just have to paint the bathroom ceiling now. Overall this works very good, and is very quiet. All I can hear is the sound of airflow. If I go in the basement where the unit is, I can hear the motor but it's a very soft and faint sound. The dehumidifier overpowers it. This probably ended up costing me like 500 bucks in materials but in the end it was well worth it, and it is highly maintainable if needed. I even added a cleanout.
