Shower curtains are great, but nothing holds them back. They crowd or cling to people 43% of the time ... yuk! Our amazing shower curtain expander installs in seconds ... no tools! Works on all standard curtains and rods (even tension rods). Creates elbow room, without lifting curtain from the tub. Clear bow flexes easily side-to-side. Then, the space capsule tips back with just a nudge. So unlike curved rods, it won't crowd the rest of the bathroom. A simpler solution to enjoy the luxury of more shower space.
