Do I need to drill to install a shower curtain rod?

Most rods in this category are spring-tension models that wedge between two walls with no drilling required, which is ideal for renters. Curved and clawfoot-tub rods sometimes offer both tension and permanent screw-mount options for extra stability; if you want a rod that won't slip under the weight of a heavy fabric liner, a screw-mounted or industrial stainless model is the more secure choice.
