Our two-storey house has a washroom on main floor, and it has no exhaust
fan. Don't want to make a fan on exterior wall (direct vent out), as our
winter is too cold.

I'm thinking to place a fan into interior wall, and get duct up to attic
inside drywall, then vent out from roof. I wonder if this is feasible. Are
there exhaust fans thin enough to fit into interior wall which is only 4-5"?
Is this too big a job to make through from main floor to attic (e.g. drill
holes on 2x4s)? If doable, I may pay to get an expert to do it.

Any input appreciated.

John

Hi,
Can't install ceiling fan?
Here it is cold in winter as well(Calgary Alberta). Ceiling fan is
vented outside between floor joist through wall. ducting is insulated.
Exhaust has a flaps (one at fan box, one at the wall which opens only
when fan is on.

Why do you need a fan? I have 2 1/2 baths and a fan in each, but I
only use the one in the room where visitors take hot baths or showers.
And when I use some terrible poison, which is a about every 5 years
for one hour.

In the powder room on the main floor, I unplugged the fan and haven't
used it in 24 years. (0ne fan came with a wall switch and I put a
switch for the other fan when I put in a wall light.)

If you insist on putting one in, put in a pull chain switch or a wall
switch, so visitors can turn the damn thing off. I'd rather do my
business or wash my hands in a public bathroom with no fan or a
distant fan than listen to the racket that even quiet home fans make.
The fan is no way to make guests feel at home.

(For the first 36 years of my life in 2 houses and 3 apartments every
bathroom had a window.)

I'd much rather listen to a little bit of noise from a bathroom fan
than smell the stink for two hours from whoever used the bathroom
before me. Or are you going to tell us your sh** don't stink? Plus
many bathrooms can wind up with moisture damage problems from excess
moisture from showers without having proper ventilation.

There are plenty of fans that are very quiet. All you have to do is
pay $75 - $100 or so, instead of the cheap $30 builder models. Look
for the SONE rating.
