Venting bath fan through floor joists. PVC best option for vent?
I am putting in a bathroom in my basement and trying to run the vent to the fan. I am concerned about not having access to the vent duct in the floor joist if something were to come apart or rip.
I am considering running 4" PVC from the fan to the wall with a 90-degree elbow where I will attach a semi-rigid vent duct and carry it out to the vent in the wall. The reason for this is, by means of pulling out a recessed shelf I will have access through the wall if I have to fix the vent for any reason but the 90 degrees will be so tight I would not be able to snake a new duct through to the joist.
Is this the best way to go?? Any suggestions or ideas are appreciated.
PS: Also, should the duct be insulated in any way to avoid condensation or will that not be an issue where the temp shouldnt be much different between the joists?

You could but it would be better to use rigid duct. If pvc works best with your fan, it might make the most sense.

You can use the snap together duct. You aren't going to get any condensation in the ceiling because you are using a 90 and venting below.
