my daughter uses a small plastic stool to stand on while we brush her teeth, but she definitely can't reach the sink. I would like one that she can reach the sink to wash her hands (with help) and I guess possibly to get onto the big toilet if she prefers an on-the-toilet potty seat over the small one.

any tips? I don't want to spend a fortune, as much as I like the look of the Kidkraft one. any cheap plastic ones that have decent height?
