Fit an L-shaped shower curtain rail to a metal stud wall

Fit an L-shaped shower curtain rail securely, choosing the correct fixing for your bathroom wall type.

SC-01Plan the rail route and mark the fixing pointsDecide where the L-shaped rail sits around the bath or shower tray, keeping it roughly 1800-2000mm above the floor so it clears your head. Hold the rail up, mark the corner point and both end points with a pencil, then check the run with a spirit level so it's level and square. Most L-shaped rails need three brackets: one at each end and one at the corner - mark all three now.

SC-02Work out what's behind the wall at each markScan each marked point with a detector, then check with a magnet or by tracking a line of screw heads under the tiles - screws in a straight vertical line usually mean a timber or metal stud. Tap the wall: a dull thud is solid brick or block, a hollow sound is a stud wall or dot-and-dab plasterboard. If you're still unsure, drill a small pilot hole - timber dust means wood, fine grey swarf means metal stud, and a soft dusty give with no swarf or timber usually means dot-and-dab or lath and plaster.

SC-03Check for cables and pipes before you drillRun the detector over every fixing point, but still treat the wall as if something's there - detectors miss cables that are deep, run in metal conduit, sit behind metal-backed board, or are confused by a metal stud frame. Find your stopcock, usually under the kitchen sink, and check it turns freely so you can shut the water off fast if you hit a pipe. If you have any doubt at all, isolate the circuit at the consumer unit and turn the water off at the stopcock before you drill.

SC-04Drill through the tilesStick a strip of masking tape over each mark so the drill bit doesn't skate on the glaze. Start with a tile bit at slow speed and light pressure until you're through the glaze, then swap to the right bit for what's behind - masonry bit for brick or block, an ordinary bit for timber or metal stud. Keep the drill square to the wall and stop the moment you're through the tile.

SC-05Fixing method: solid brick or blockDrill to the depth stated on the wall plug packet, usually 50mm, using a masonry bit one size larger than the plug. Blow or vacuum the dust out of the hole, tap the plug in flush with the tile, then drive a 4x50mm screw through the bracket and into the plug.

SC-06Fixing method: plasterboard on timber studsDrill a 2mm pilot hole into the centre of the stud you found in step SC-02, then drive a 4x40mm wood screw straight through the bracket into the timber. Don't fix into plasterboard alone at a point that takes regular pulling force - shift the bracket a few mm if needed to land centrally on the stud.

SC-07Fixing method: plasterboard on metal studsNever use a plain plastic wall plug or an ordinary wood screw in a metal stud - it strips straight through the 0.5mm steel almost instantly. At the corner bracket, which takes the heaviest pull when the curtain is used, try to land at least one screw into the metal stud itself using a self-drilling metal-stud fixing. For any fixing point that falls between studs, use a hollow-wall toggle rated for at least 10kg, and if the bracket feels like it flexes when you tug the curtain, add a second toggle alongside it rather than trusting one.

SC-08Fixing method: dot-and-dab plasterboardDot-and-dab plasterboard sits on an air gap before it reaches the solid masonry behind, so a standard plug won't grip anything. Use a long fixing - a 7.5x100mm frame fixing or a dot-and-dab specific hollow-wall anchor - that passes through the board and adhesive dabs and bites into the masonry. Check the fixing feels solid, not spongy, before you tighten it fully.

SC-09Fixing method: lath and plasterLath and plaster is brittle and can crack if you overtighten, so drill gently and go slowly. Where you land on a timber lath, fix the same way as a stud with a 4x40mm wood screw; where you land between laths, use a plasterboard-style toggle rated for the load, and seat it carefully so it doesn't crumble the surrounding plaster.

SC-10Mount the brackets and hang the railFix all three brackets using the method that matches what's actually behind each point, checking with a spirit level as you go so the run stays level and square around the corner. Slot the rail into the brackets and tighten any grub screws or clips. Give the whole rail a firm downward and outward tug at each fixing point to check nothing moves.

SC-11Fit the curtain rings and testThread the shower curtain rings onto the rail before final tightening if your rail doesn't have a removable end cap. Hang the curtain and pull it fully open and closed several times, checking every bracket stays tight and the rail doesn't sag at the corner.

SC-12Seal and tidy upRun a thin bead of sanitary silicone sealant around each bracket base plate where it sits over a drilled tile, to stop water getting behind the tile. Vacuum up dust and swarf, wipe down the wall and bath, and bin any offcuts or packaging.
