The plumbing is in. It goes through the floor and onto the ground just like I like it. No gray water hassle. I toyed with the idea of throwing a T-junction on the pipe and adding a ghetto urinal. I guess I don't have space for both a urinal and a sink. But I guess the sink could act as a urinal. Or the urinal could act as a sink. Maybe, just maybe, I have both a urinal and a sink.....or did I just blow my own mind?
