Install a Curved Shower Rod

The curved shower rod appeared in hotels first, where every inch of perceived space matters. What looks like a simple bend is actually a small piece of geometry that buys you six to eight inches of elbow room in the shower without changing a single tile. The curve pushes the curtain outward, which means it stops clinging to you mid-shower and gives you a noticeably larger sense of space. Installation takes about an hour and requires only basic tools, but the difference between a rod that stays put and one that sags or pulls free comes down to how you anchor it. The outward curve creates lateral force on both mounting points, so this is not a pressure-rod situation. You need proper wall anchors or, better yet, studs. Get the mounting right, and the rod will outlast the curtain by a decade.

1. Mark mounting height and test fit. Hold the rod up to where you want it mounted, typically 72 to 75 inches from the tub floor. The rod should sit high enough that a standard 72-inch curtain hangs just inside the tub edge. Mark both wall positions lightly with pencil, then hold the rod's flanges against those marks to verify the curve projects evenly into the shower space. Adjust height if needed so the rod sits level.
2. Locate studs or plan anchor placement. Use a stud finder at both marked locations to check for solid wood framing behind the tile or drywall. If you find studs at both ends, mark their centers. If not, plan to use heavy-duty hollow-wall anchors rated for at least 40 pounds each. Curved rods exert outward pull, so anchoring strength matters more than with straight rods.
3. Drill pilot holes. For stud mounting, drill a 1/8-inch pilot hole into the stud center at each mark. For hollow walls, drill holes sized to your anchor's specifications, usually 3/8 to 1/2 inch depending on anchor type. If drilling through tile, start with a 1/4-inch carbide or diamond bit at low speed with light pressure to penetrate the glaze, then switch to the correct size bit to finish the hole through the substrate.
4. Install anchors if needed. If not mounting into studs, insert your hollow-wall anchors according to manufacturer instructions. Toggle bolts work well for drywall behind tile. Tap or thread them into the drilled holes until the anchor flange sits flush with the wall surface. Test each anchor by tugging firmly before proceeding.
5. Mount the first flange. Position one rod flange over its hole and thread in the mounting screw, tightening until snug but not fully torqued. Leave it slightly loose so you can make micro-adjustments when you mount the second side. Make sure the flange sits flat against the wall with no gaps.
6. Attach the rod and mount second flange. Slide the rod into the first mounted flange, then extend or compress it to the correct length for your shower width. Position the second flange over its mounting hole while holding the rod level, then insert and tighten the screw. Check that the rod sits level and the curve projects symmetrically into the shower space before fully tightening both flanges.
7. Tighten and test for stability. Once both flanges are positioned correctly, fully tighten both mounting screws in alternating passes to avoid cocking the flanges. The flanges should sit completely flat with no wobble. Pull downward and outward on the center of the rod to test the mount. There should be no movement at the flange connection points.
8. Hang curtain and adjust if needed. Attach your shower curtain rings and hang the curtain. Close the curtain and check that it hangs evenly with the hem inside the tub on all sides. If the rod sags slightly under the curtain weight, re-check your anchor installation. A properly mounted curved rod should show no visible deflection even with a heavy fabric curtain and liner.
