Tub setup is fairly simple.

This is mine, not super flashy but it gets the job done. If you get a bigger tub you have more flexibility for "decorating". Tub setup is about the same as a vivarium setup.
As for heating the tub, I use aluminum tape and tape a UTH to the bottom of the tub on one side. This works well for me so far.
