Bathroom exhaust fan

Barry J

I have a 9x5 bathroom, I have a tiled bath/shower with a full sized window in the shower, the tiles are loose and the window is crap. We are getting a 18 in high tub, and a shower surround, the surround we picked is 72 inches, I at first wanted to put a same Harvey window in, just below the ceiling, but with the tub and the surround we picked out, doesn't leave me any space for the window. I have a exhaust fan now that I got 5-7 years ago, it's rated at 70cfm, but even with the window i still get condensation on the mirror, walls and ceiling. So, I'm going to upgrade to a better exhaust fan, maybe one with a heater and higher rated cfm.
Does anybody have any suggestions on what to buy??
I'm either going to lowes or home Depot, unless someone else has a better place.
And does anybody know about the exhaust fans with the heaters?? Any chance of fires with those, since I would have insulation surrounding it in the attic???
Thanks

Where does the present fan get its replacement air?

In situations like yours I'm a big fan of the Fantech remote systems (I have three installed at my own house):

often you can snake a duct and install an inlet over the shower/tub:

do not know what you are talking about (replacement air)
The exhaust fan is in my ceiling in my bathroom, it's mounted to the attic floor, and then piped out thru the roof of the attic.
As for replacement air, i don't know??? what do you mean, do I need to keep a door open, so my 6 year old doesn't get sucked up into the fan????

Most people have the bottom of the door cut so that there is a 1" gap between the threshold and the door bottom, so the air that gets exhausted is replaced by fresh air.
For high CFM this gap may not provide enough entrance/replacement air.

After research I went with a Panasonic fan for my recent bath remodel and have been very happy with it. Quiet and powerful. It doesn't have a heater (though they do make one that does). My other bath has a Home Depot model fan and it has proven impossible to keep balanced, which means noisy. More budget-friendly though, of course. Depends on whether you're able to spend more to get better quality.

I'm looking at getting one that's about 100cfm, and i do have about a one inch gap at the bottom of my door.
But, just curious what happens if you don't have enough replacement air in the room???

In my older (1910) house, before the bath door was cut higher, it would draw from the :gaps around the sink drain pipe, toilet supply gaps at pipe, side of the jambs and head on the door, light fixture gaps, and around the shower pipe. Smelled like crawl-space air!

huh... the things we learn.

i like your picture of the mega fan with the distrobuted ducting. with the fan in the attic it is probably quieter too.

i think i could use something like that. i have a 8' x 10' master bath with the quietest fan i could buy from HD and one that was rated for that room space. but i still find a lot of condensation on the walls.. so i need to upgrade to more powerful.

and putting the grill directly above the shower could be good idea too? hmm..

The walls are cold and uninsulated?

Knucklez

it shows up on all walls, not just exterior. with concentration around walls near the shower. the exterior walls are insulted with blown in celulous.
