Looks like a homeowner job!

From the submitter:

"The only place for the dryer to vent in the new house is out of a small window inside the downstairs water closet. It took a couple of reused bed slats to get it to stay on the toilet. Safety first!"

When you've got to s*, it's got to fit!

What has been seen cannot be unseen. But it could very well have been covered up with a divider.
