A whole lot of us have looked at some fixture in our home and thought "man, it wouldn't be too difficult to gussie that thing up a bit. I could borrow Doug's saw and crack that baby open. Maybe throw some extra pipes in there. Yeah, I could have a super toilet." Most of us who have that thought realize very soon after that it's not as easy we might think it is. The rest of us go for it and end up with some low budget DIY engineering solutions.
