About vent fans with lights for bathrooms? I am researching the Panasonic 80 CFM that looks like a can light (FV08VRL1) for our yet to be remodeled 8x11' master bath. One will be installed in a water closet that will be approx 3' x4'x9' high. The other in an enlarged shower (approximately 4 x 5'). Again, both will be 80 CFM each. My question is, will these two fan lights be sufficient for this 8x11' space. One contractor says yes while another contractor thinks we need two 120 CFMs. The fixture I am considering does not come in a 120 CFM. BTW, I phoned the company that makes this fixture and he assured me that two 80s are sufficient for 88 square feet. What say you?
Might check this out?
I have always heard 1 cfm for each square foot of floor space, and your 2 80cfms sound right. But I checked to make sure, and it could also vary a bit depending on the type of tubs and showers you have (amt of steam in other words). Also make sure you have enough space under the doors so air can be drawn in, as it is exhausted.
btw..I really like the timers that I have installed on our bath fans. No need to remember to go back and shut the fan off after leaving the room.
Conrad, thanks for your tip and link. Looks like two 80 CFM units are fine. I won't have a steam shower and the shower, it appears, will have two glass panels...one being the door. I bookmarked that site. Thanks again.
It is hard when you get differing opinions from two contractors. It could be the one is just more familiar with the installation style of the 120 cfm fans he was recommending, or just less familiar with the 80 cfm ones you chose?
We have one of ours (center of bathroom ceiling)linked to the light in the shower stall. So the fan and shower light both come one together. This way the fan is working at the same time the shower is running...and because they are also on a timer, no steam buildup in the bathroom.
Conrad, regarding getting opinions from two contractors, I agree it becomes confusing so you can imagine how it must be with THREE.
One of the designers returned and the computer image of our bath design was nothing like what we discussed. This sends a red flag as our sense is we were not heard.
It does appear that all three vary in their design preferences sometimes canceling each other's opinions unknowingly. I suppose three opinions can be a good thing if two are on the same or similar pages though.
Update: I called the company who makes the lighted fans and he verified that 2 80 CFM fixtures is fine for my space. He added that the toilet tissue will be blown away if I used 2 120 fixtures.
Those two large fans might be ok...if...that it would s-uck up all the dust, lint and stray hair along with it and spew it outdoors.
Now that would be one ideal bathroom fan.
