Shower rods allow your shower curtain to hang above the shower or above the bath/shower combination. Shower rods are essential to make sure that your shower rings are appropriately placed and that your curtain hangs far enough above the floor and in the right location to prevent water from escaping from your tub and sloshing all over the place. When your shower rod becomes dented or damaged or if you simply want a new look, you may need to purchase a replacement.
Builders supply stores
There is a number of different builders supply stores located in almost every geographic area. These usually have names ending in "Building Supplies" or "Builders Supplies." These stores sell items that cater towards home builders and contractors who are building or remodelling houses. They often have a wide range of products, including shower curtain rods. If you are looking for something like a round shower curtain rod, an oval shower curtain rod, a curved shower rod or something unique, these might be good places to find it.
Home improvement stores
Home improvement stores that cater for the general public may also be a good place to get a shower curtain rod. These are usually large stores that have a wide variety of different kinds of building supplies and materials. One example of such a store is Lowes. You can find a good selection of shower curtain rods there, although the selection may not be as good as you would find at a builder's supply shop or store.
There is a variety of other potential places you can go to find a shower curtain rod as well.
Specialised stores Some stores that specialise in plumbing, bathroom and shower products may be able to provide you with a shower curtain rod, but usually this is true only if they are full service building and design centres rather than just people who carry faucets and faucet valves.
Stores selling closet materials and the Internet Stores that sell closet materials like closet rods may also be able to help, since a shower curtain rod is essentially just a long rod that mounts on both sides of your wall. Finally, the Internet is another place you can go, but you need to pay attention to what the cost is, to ship the long and unwieldy item.
