Ruby told the Bay of Plenty Times the results surpassed her expectations.
"It's a pretty cool bedroom. It's every kid's dream come true, for sure," she said.
"It was really fun helping Cocksy build the chaise lounge and helping decorate the chandelier, paint a chair, and filling the bean bags. All the people involved were really nice. I'm a very lucky girl."
Choice TV's Holly Pollock said: "It's been great to see such incredible creativity from the youngsters across the series. Some of their ideas have been real problem-solvers, like the stage that turned into a bed, and others created by Cocksy, such as Ruby's hanging bed.
"All the rooms have provided viewers with some real Kiwi-can-do DIY projects that they can bring to life in their own homes."
