You can make one yourself if you're handy, using regular drawer slide hardware. You'll need some sort of 'container' for the laundry and to make a frame, but it can definitely be done. Took my DH about half a day to retrotif a standard single-door cabinet into a trash pullout for our kitchen island. (Non-standard size)

I plan on having one made up for my bathroom. I saw a TV show where they made a canvas type liner that had tabs with snaps and then attached heavy duty snaps to the pullout. So you could just snap off and go. I was thinking if you seal/varnish/paint the inside, maybe a person could get by without a liner? I am not so worried about "dirt" as I am wet towels.

Interesting about the canvas bags. They would catch all the fine grit, and could themselves be washed. hmmm.

sweeby, great idea. I actually have 2 tall mesh baskets from Container Store that could perhaps be our starting point. I'm not particularly handy, but DH is fairly so.
