Anywhere could have heavy ceramic bowls, walmart, petco, any pet store. The only time mine have bowls big enough to soak in is if they are having shedding problems or I am trying to raise the humidity a bit, Spagum Moss works great for this. If you are keeping your snake in a tank it would be easier to have a larger bowl without taking up all your space as opposed to a rack or tub where a larger water dish could possibly take up all the snakes room.
