Jay, We also have a Blackwood with the large shower and 3 piece door. I believe my shower door is installed backwards, since the overlap faces the spray. Even with the squeegee between the sections water still escapes. For a quick fix on our first time out, we bought a spring tension shower rod and a cheap clear curtain. We have decided that we really like this setup because no water even hits the door and there are never any water spots to clean. The curtain is not noticeable when the curtain is slid back and the doors are open.
