IGUANAS DON’T DRINK WATER FROM BOWLS
It’s not common, but captive iguanas can drink from water bowls. Of course, their main sources of water include their food, the humidity, and bodies of water where they swim. If they need more water, they could drink like a dog with a water bowl. Another interesting way to get them to drink is by spraying them on the mouth with a water bottle -- it seems to do the trick just fine.
