All of my snakes have hides, varying from a T-shaped PVC connector for my baby royal, to a cut beer box (don't laugh, at least it is a microbrew rather than some generic piss-water). For water dishes we generally use Pyrex bowls we have found at the dollar store nearby. For one of my wife's snakes, she has made a hide out of LEGOs, and builds a new one with each new season/holiday...right now there is a giant skull in his tank.
