I have been rebuilding my basement with my father it has all been completed except for the bathroom. The walls are framed and the plumbing has been roughed in. I just don't know what to do next. My Dad is super busy right now and whenever I ask what I can do his answer is I will get over there soon... That was almost a year ago and I have had enough and plan on finishing it myself. Can someone please tell me what I need to do next?
