No problem. Looks like you got all you need. Only thing I may add to the list (except, of course, the water bowl you're inquiring about), is a set of those bungee cords. I think they're usually found in the automotive/hardware section of stores. If you want to be super duper extra sure the tub is closed all the way, you can wrap one of those around it.

As far as the water bowl goes, 3-4" diameter for a hatching should be fine.
