For my sink, I've preferred to use MDF which is stable and doesn't crack or delaminate. I treated it with two layers of a very fluid varnish that goes deep into the wood's pores as to make it as waterproof as possible and finally 2-3 layers of bi-component polyurethane paint, the heavy duty one used for garage floors (that thing stinks as hell when wet but has no odor once dried). It's working fine for 8 years now and shows only light signs of wear. I'm pretty sure a tray ladder made this way should also last pretty long.
