Shower Curtain Holder The water was being sprayed in the shower and the curtain apparently was not shut all the way on either side. So, this means the water would at best hit the curtain then either hit the wall and drain out onto the floor, or miss the curtain all together. I used velcro squares and some silicone on both the shower wall as well as the curtain to hold it shut (I also did this on the other side to hold the other end closed as well).
