I'll get a picture soon, but I made one out of PVC and suction cups. I wound up having to modify it to hang from my shower caddy because the marlite lining my shower isn't smooth enough for the suction cups...
But all you need is some half-inch PVC pipe ($1.50ish), a hacksaw (or get them to cut it for you)and four elbow joints. A drill is handy to make the holes to put the suction cup hooks into. Anyway, more later. It's super cheap and east to do and comparable to the store bought ones that sell for over $20. You just need to hang a washcloth or something on it so they can grip it. If you wanted to get fancy, you could even make a cover for it. smile
