Bathroom

12ft x 6ft (10ft ceiling) - Need to operator via light switch and stay
on timer 20mins after etc

I've found a better approach for bathrooms is to have a low power
(and hence very quiet) fan running for several hours a day. Assuming
you have done your back pressure calculations correctly (don't ask an
electrician - most wouldn't know where to start) and the fan will
cope a 15W fan running for about 4-8 hours a day will create a much
dryer atmosphere than a 100-200 W running for 2 hours.
