Thanks everyone!
Luanne...I do have TONS of dust and cat hairs.
Everywhere. 
But I do have a cleaning lady who comes every 2 weeks.
Her project last week was to clean all the ceiling fans,
cuz they were starting to 'throw' off dust bunnies the size of squirrels.
And those dust bunnies hit the floor running,
and I swear sometimes they nip me on the ankles.
I am a terrible house cleaner, HATE to do it.
Hubby says I was royalty in my previous lives, that's why.
I don't advise orchids in the bathroom, unless you have a ceiling fan in there and keep it on low all the time.
Orchids LOVE humidity, but they also love bright light* and air movement.
A simple vent fan in the ceiling wont do. The air needs to 'blow' around,
not simply be sucked upward. And most bathrooms I have see, do not have sufficient light.
Not only that, bathrooms are only humid during and right after someone takes a shower.
Within an hour or two, the humidity is low again.
*Lots of people would disagree, but lots of people take plants tags to the extreme, think low light means no light.
If you can't read comfortably in the room without the light on, there is not enough light to grow an orchid, yet alone any plant.
There are PLENTY of orchids that will grow in normal household humidity on a bright windowsill.
Any room that has a lot of light and a lot of air circulation (ceiling fan on low blowing down) will be good for most dendrobiums.
Why do orchids need so much air circulation?
Think about their natural habitat...most orchids grow in trees, attached to the bark and branches by their roots only.
No soil, no bark chips. Maybe some moss and some built up decayed leaves and twigs in the crooks of the trunk and branches. Up in the trees, the air moves freely, if not a bit windy. The roots NEVER sit in moist dark areas with no air or light.
You gotta make those orchids feel like they are 'home'...but not in a house.
And each ochid comes from all different parts of the world, all different climates,
so there is at least one type of orchi you can grow.
