Why are bathroom exhaust fans mounted in the ceiling?

Wouldn't down low next to the toilet be a better location?

Maybe even lower than the toilet and behind the toilet. Then the
"smell" would go down and back instead of forward and up!



Methane is lighter than air and floats to the ceiling.


Methane is odorless, so what's the diff?


If the OP's that concerned about flatulant odors he could always
scrounge around used building material yards and pick up an American
Standard "Ventaway" toilet. (AKA in my youth as "The fart catcher.")

Repair parts for them are still available.

They stopped making them quite a few years ago, probably for water
conservation reasons. They used running water to pull the air out
of the bowl and send that air down the drain after the trap section of
the toilet.

IIRC you pulled up on the flush handle to turn on that water flow before
you sat down. Pushing down on the handle to flush the toilet stopped the
venting water flow.
