Short extendable rods are everywhere. Current up to 3m extendable mast only with this provider, which fills a gap. Actually, the term is misleading, because very few will use this rod in your shower, at least not in the full length. "Telescopic clamp curtain rod" is more like it, because I use this bar in the living room for my curtain. A conventional curtain rod lasts me because old porous plaster for a minute so that I had to look for an alternative. I have the rod extended to over 2.5 m, up pulled the curtain and the rod clamped between the walls (not about safe with all the windows - depending on the type of room). Keeps properly and flexes only slightly. Someone wrote that for him, the tension did not last very long, I have also glued two small sticks under the rod ends to the wall, so not all rushing in the worst case the same down, but until now (about 3 weeks) holding the rod as branch. Ergo: 5 points.
