I have a Moen single curved rod. I've only had it for a month or so, so it's too early for rust. However, I purchased it based on very good reviews, both here and on Amazon. I was originally planning on getting a straight tension rod, because I needed my head examined. I had this notion that drilling holes in my new tub/shower surround tile was too heinous to consider. I even talked myself into thinking that the straight rod provided enough room while taking a shower. That may be sorta true. I'm small and don't fling my arms around a lot in the shower. I would have been fine and not emotionally scarred. I finally had a moment of reason and let them install the curved rod. Not, mind you, until I'd been very scientific about finding the exact sweet spot for its placement. It is wonderful. Seriously. The shower feels quite spacious in width with the curtain closed. I also like that outside the shower it doesn't look at all strange or bulge-y. Almost like an optical illusion. Don't worry about the point where the two sections of rod meet. There's a little plastic thing that slides over it and if you use rings with ball bearings, they slide over it without a hitch.

What do you mean by "a 48-inch shower?" I assume not 48 square, since that's a huge shower with no possible elbow room problem. We put in a shower that is about 48x32. We went with glass doors, not a curtain, but I can say that at 32 inches there is still no elbow room problem.

Hi, Our shower has an angled wall in one end. Currently there's a straight shower rod attached to the straight wall and to the angled wall via a swivel flange. The shower feels small due to the angled wall. I'm thinking about installing a curved shower rod to gain a little more space. Has anyone tried to use a swivel flange with a curved curtain rod? I'm not sure if the rod end would fit properly into the swivel flange. Thanks for you advice! Padmini

I put a tension-curved rod up because I wasn't sure if I'd want a curtain or glass sliding doors on my tub after a redo. I bought this rod as a trial balloon to help me decide if I really wanted to go with a curved rod and drill into my new tile. I've never replaced it. It's never so much as budged, and my tile is intact if I ever decide to change my mind. I also mounted it high for an extra-long curtain liner. I've never been attacked by the curtain. https://www.amazon.com/gp/product/B00NBQ9BDC/ref=oh_aui_search_detailpage?ie=UTF8&psc=1
