To go one step further, whenever I have to bathe my snakes after they've played in a particularly messy poo for instance, I use a small-ish tupperware container. I fill it about 2 inches deep with luke-warm water, put the snake in, put the lid on, then set it inside their tub, directly on their hot spot. This keeps the water at ideal temps for the 15-20 minutes I leave them soaking...
