An egg box can be as simple as a large trash can on it’s side with a hole in the lid. George’s box also had a pipe “tunnel entrance” and was kept in a back bedroom where it was quiet and peaceful. It was filled with a mixture of dirt and sand. Old blankets and towels surrounded the box to help keep George from traipsing dirt all over the house.

Egg box designs will vary depending on the skill of the owner. Basically you have to provide a box large enough for your iguana to fit in comfortably and provide dirt deep enough to dig in.
