Adult assembly is required, and it took us only five minutes to do. Just make sure that when you attach the playset to the tub wall that the track is horizontal and level with the bathtub. You also want to make sure the toy is at an appropriate height so that a child can sit and play with it. You don't want your child to be standing in the tub to play. Also, Mattel says the suction cups work best on flat tile surfaces. The bathtub we tested ours on did not have tiles that were flat, and so it was difficult to keep the playset from slipping and falling off the wall. It also didn't stay on very well when stuck to the actual tub, which was kind of frustrating.
