I have 2 bathroom separated by a common wall. Room sizes are ~10’ x 7.25’ (80 CFM) and 4.75’ x 10.75’ (60 CFM).
I can either install 2 separate fans each with a duct exiting the side of the house, or 1 in-line fan with a single duct to the side of the house (I saw this alternative in a Panasonic ventilation catalogue). For an in-line fan, I would use a 3 way switch so that it could be turned on from either bathroom.
1. Is either alternative ok? Or are there good reasons not to use an in-line fan for both bathrooms?
2. If I use 2 separate fans, can they both be vented through a common duct to the outside? If not, why not?
3. If I use PVC for the fan duct work, do I need to be concerned about condensation on the ducts and insulation around them in the attic? Ditto for galvanized aluminum?
4. And what fans are of better quality - Panasonic, NuTone, Broan?
Thanks - the last item I need for my bathroom remodeling.
