Our cat was peeing on our laundry (no, I'm not kidding) so my wife requested a laundry sorter. Since I have three small children (and hope to have more) I was compelled to grant the request. (Plus I don't really enjoy the smell of cat pee.. especially on my clothing). Anyhow, this is 5 bin PVC Laundry Sorter that is built with PVC pipe, fittings, snap clamps, a piece of fabric, some laundry bags, and of course a few safety pins.
This isn't complicated, but here's my basic plan. I decided to put a lid on it (to keep the cat away). The lid certainly isn't required. But it is kind of cool to use the these slip on PVC tees to create things that you might not otherwise be able to do with PVC.
