You've decided to replace not only that stained and discolored shower curtain, but the shower rod holding it in place as well. Maybe it's flecked with a few rusty spots or the shine has worn off, but whatever the reason, you have purchased a new one. Trouble is, your replacement shower rod is too long. However, shortening it will take only a few minutes and require a couple of basic hand tools.
Things You'll Need
Shower rod kit (either metal or plastic)
Screwdriver (slotted or Phillips head)
Using your screwdriver, remove the screws from the end flanges/supports of your existing shower rod. Set them aside.
Stand the existing shower rod next to the new one you have purchased. Using the marker, make a small mark on the new rod. This is where you will cut with your hacksaw. Set the old rod aside.
Using the file, make a small groove on the shower rod. Press gently so as not to bend it. The groove will hold the blade of the hacksaw and keep it from sliding on the smooth finish of the new shower rod.
Using the hacksaw, cut the shower rod. Use a slow, smooth sawing motion so as not to crush the end of the shower rod. When finished, set aside the small bit of rod you removed.
Using your file, carefully smooth the end of the new shower rod to remove any loose bits of metal or plastic.
Slip the new rod end covers/holders over the ends of the new shower rod and reattach them with screws. If the old screws are not rusty, you can reuse them. If they are, discard them and use the new screws included with in your new shower rod kit.
When cutting the new shower rod, lay a piece of newspaper under the cutting area. This will catch any metal or plastic slivers. When using a hacksaw, a slow, steady motion will allow the saw to cut properly.
