The Duo is a space-saving dual-rod system that functions as both a shower curtain rod and a towel bar. Taking cues from behaviors witnessed in cramped bathrooms, the Duo acknowledges the common practice of hanging towels over the shower curtain to dry, often remaining there until the next shower, and redesigns the rod to make it more practical for such habits. In addition to space efficiency, the outer rod helps wet towels resist mold and mildew by keeping them away from the wet shower curtain. The rod can be easily pressure-mounted by using the tool-free quick-lock assembly or screw-mounted directly to the wall.
