I had the same issue with our 3100 SS. I got a small spring loaded cafe rod and some shower curtain hooks and installed it just above the shower door. Then cut a clear shower curtain in half ( longways) and clipped it to the rod. Just close the curtain when showering and open it when done. No water on the door or the floor.
GL1800 I see you are in Citrus County, Florida; so am I.
