Not sure if this is the right forum to post this, but you all have been so good with everything else I thought it worth a shot.
I'm in the process of roughing in a new bathroom in my basement. I'm looking for feedback on my exhaust fan plan. Bathroom is 5x11, eight foot walls. The fan will sit in the joist bay (obviously) and the duct will run about one foot in the bay to the wall, where I then need to drop the duct below the joist to run it along the wall in a chase for about 18 feet. At that point I hit a plumbing obstruction (main stack). I plan to use flexible duct for the first two feet, PVC for the next 15ish and flexible again at the end to get around the stack. There's an existing vent cap in the rim joist which means the duct will need to go back up at the very end to connect to it. To sum up, it will go down, over and back up for a total run of around 18-20'. No 90s if i use the flex stuff, but will use PVC in the middle. I plan on insulating the entire thing. Fan will be minimum 110CFM (probably Panasonic).
Am I missing anything? Are there any problems I'm not noticing?
Thank you.
