Getting ready to remodel my bathroom and I'm thinking about installing an inline fan to reduce noise. I'm looking at Panasonic 120 and 240cfm models.
Bathroom is 7' x 8' x 8'. With a shower in one corner, and a toilet in the opposite corner.
How many CFM do I need? Does it make sense to install a Y, and separate pickups over the bath and toilet?
The usual rule of thumb is to equate square footage to CFM.
7x8= 56 SF => 56 CFM. Rounding up to 80 is typical.
Y'd pickups are nice.
The ceiling mounted Panasonics are plenty quiet, though (meaning just 1 pickup). I prefer exhaust fan closest to (or in) the shower (new Panasonic with recessed light is very nice) and connected to a countdown timer.
Be sure to have any shower electrics run from a GFCI.
