for my royal's I had the ceramic rabbit bowls you can get from every pet shop or the likes of wilkinson's etc. This seemed a good size as they were able to curl up I'm them nicely.
I downsized my laate 07's water bowl. He didnt curl up in it and i've never sseen him drink so he has a smaller bowl changed daily and he seems a happy chap. Moist hide (5ltr RUB with moss) when his eyes g blue until he has shed for additional moisture/ humidity.
