For small snake water dishes I like the melamine pet bowls from the dollar store. My juvenile corn and king snakes (kept in tanks on aspen substrate, not tubs/racks) also like them as they can hide under them. I looked at the ceramic bowls and passed as many were cracked. Other folks have recommended the heart and star-shaped candy/potpourri dishes for their adults since they're almost undumpable. My largest snakes get sterilite tubs that have a large footprint but aren't tall, again so they're less likely to be dumped when the snake decides its bath time (moreso the boas than the ball pythons).
For snake hides, don't laugh, but these are all very inspensive or even free (after you eat the food): margarine or whipped topping tubs, the plastic containers for Manchuran-brand or take-out meals, small plastic planters/seedling pots, Glad-brand "Oven Ware" containers, plastic mud/cement mixing tubs, and plastic bus pans (like a restaurant would use).
