Shower curtain rod is a telescopic support rod used to hang shower curtains, usually with an inner and outer pipe structure, where a small pipe (inner pipe) extends into a large pipe (outer pipe) and is fixed by an inner buckle, spring, or screw. After installation, the shower curtain can be easily hung to block splashes and prevent wind during showering, while also helping to keep the bathroom warm. The shower curtain rod is easy to use, inexpensive, and easy to replace. It is an ideal product in the era of cramped living, solving the problems of limited space and scattered water splashes.
