Shower curtain rod refers to the telescopic support rod used to hang shower curtains, which is simple to use, inexpensive, and easy to replace. It is generally an inner and outer pipe structure, where a small pipe (inner pipe) extends into a large pipe (outer pipe), and the shower curtain rod is fixed using an inner buckle, spring, or screw, and then hung on the shower curtain. It is an ideal product in the era of cramped living, solving the problems of limited space and scattered water splashes.
