What a brilliant idea and a solution to my problem. I rent a patio villa built in 2005. Had the sliding glass doors with the privacy glass. I noticed that a seam looked like it was coming apart so my landlords had the old shower taken out and a new one put in. It is beautiful but the frameless glass doors let air in because they don't meet in the middle like the old ones. I have to sit on a bath bench & this air blows on me. I was trying to figure out how to stuff this gap while taking a shower. Your idea is great but I wonder if I can find a spring shower rod long enough. I'll just have to check.
