28DSBH Shower curtain rod
28DSBH owners I need your help. In my quest to get a wee bit more space in the tub/shower I want to install a new folding shower curtain rod similar to the Extend-A-Shower Expanding Shower Rod that CW sells. It requires two holes drilled on each side for screws. My stud finder is a bit inconclusive on the left side so it's difficult to tell where these screws would be properly located. I've never seen the inside of these walls so don't know what materials are in there. Has anyone done this and where did you drill?
