For their final White Room Challenge of the series the teams had to build a kids' room, given a storeroom of materials to choose from full of colour and fun. The contestants all reverted into childlike states as they got the jobs done, which proved an emotional experience for the parents among them. From the Grey Team's fort to the Green Team's cubby house, the results were inspired. Brendan then introduced the guest judges: screaming kids aplenty, who would each cast a vote for their favourite design. Mel and Keenan took the win with their ambitious effort, winning them the help of four tradies for 48 hours courtesy of Rexona.
