Every time when showering the wall outside of curtain get wet. I bought the curve rod to help with this problem but its still gets wet. Can't figure out where the water is coming from. Any ideas on this?

Why don't you stand outside the shower while someone else washes themselves. It could come from any number of places - water running down the wall inside the shower, splashing over the top of the curtain, running along the top lip of the tub.. .

Please explain just what type of a shower that you have. What kind of walls? Floor? If the shower's enclosed why do you need a curved shower rod? If it's not then tell us what wall's getting wet. Regards, Tom
