The bathroom is the hardest room to share. Whether it's between two people  or a whole family, it can get pretty tricky. To show people how easy it is to share an IKEA bathroom, we built one and asked people to Tweet pictures of their favourite items with #ShareTheBathroom for a chance to win a gift card and make their own bathroom easier to share. In 3 days we generated almost 5 million Twitter impressions, and showed everyone that sharing an IKEA bathroom is easy.
