Sure. It's done all the time. In fact the 'code' in my area requires a
bathroom to have either a) a window or b) a fan-driven vent.
So, to answer you question, you can install a fan-driven vent and exhaust
the air up through the roof or sideways through the wall.
Among other things to bear in mind:
* The more powerful the fan, the more air that will be sucked from the
living quarters; the more air sucked from the living quarters, the more
outside air that must come in to replace it. This may be a climate issue.
* The outside vent should have some sort of flap, else critters will get in
and die, build nests, store nuts, or all three.

Vent fans are sometimes wired so they go on with the
electric light. I'd dare to guess that would give you enough
air flow to help, a lot. No attic access sure changes the
options.
What's below? Can you cut a vent hole in the floor, and tie
that hole to the return air from your furnace? Or maybe run
a ceiling fan to draw air from a floor vent? Run the tube
along the cellar, and dump the stinky air out the side of
the building?

We have a vacation cabin in the remote mountains. This
place was built
many years ago, and this county is so remote, not much
attention is paid to
building codes, etc.
I have a very small bathroom adjacent to an upstairs
bathroom, that was
built as an after-thought. It is real nice, but it has
always had a
problem. It has NO ventilation. It is **fully**
enclosed, except for
the door, which leads off our bedroom.
Because the bathroom has no ventilation, it stinks, not so
much from human
use, but from mice droppings/ dead mice that get trapped in
the walls, etc.
I know that if I could air it out, it would be 100% better.
I have thought of a small window. I know that would allow
it to air out,
and would do the trick. Yet, that is a bit costly, and
would not "match"
the exterior lines of the house.
I have also thought of a ventilation fan, but I know nothing
about them.
Are they really, really, effective ? I know they usually
ventilate
through a ceiling vent, but I would prefer not to go through
my roof. Can
they be vented horizontally, with a hole on a side wall?
Most
importantly, would a good exhaust fan do as well as having a
small window
that I could open from time to time ?
There is another possibility..... on the single door on this
small bathroom,
there is a transom area, currently covered with paneling.
I could
physically install an exhaust fan there, but of course it
would be blowing
out into the bedroom. The bedroom has plenty of windows,
and thus is
well-ventilated.
Some of my ideas or comments may sound like I am a
greenhorn, and I am.
I will appreciate constructive ideas and comments. I
suppose one of my
main questions is how well an exhaust fan would ventilate
this small
bathroom, especially compared to a small window.
(Please note: Although I want things to be safe and
effective, there is no
worry about building codes here).
Thank You !!

James,
Take a look at the following link.
http://www.fantech.net/bathroom.htm
They have both single and dual intake models available, as well as through
the wall style fans. The motor portion of the "fan" unit mounts remotely
(attic, knee wall, or closet, if need be, as long as you have a power source
there) and you simply run insulated flex duct to the grill. No need for the
grill to be ceiling mounted.
As someone else here mentioned, you may be able to tie both bathrooms
together with one fan unit. On the ones that I have installed, I used a
Leviton timer switch which provides a 5, 10, 15, or 30 minute delay time
before turning the fan off.
Hope this helps.
Peter.
