Mainly, four types of shower curtain rods prevail in the market.
Fixed wall-mounted - Straight
These are single tubular rods that are fitted to the walls at both ends. The assembly consists of a fixed-length metal rod, metal brackets and screws of appropriate specifications. The simple installation of these shower curtain rods involves two easy steps:
Firstly, the two brackets are mounted on two walls facing each other at marked heights. The fixing is done with metal screws.
Then the rings or hooks meant to hang the curtain are placed in the pipe and its two ends are inserted into the "mouths" of the wall-mounted brackets. These are tubular projections of a slightly larger diameter than that of the pipe, so it fits comfortably inside the bracket.
This done, your shower curtain rod is ready to use. The assembly could have variations of metal brackets such as disks or box-type, but their function and installation method remains the same.
These shower curtain rods are ideal for rectangular, square, U shaped, or other bath spaces of even dimensions. The reason being efficient space division with the straight shower curtain rod.
Fixed wall-mounted - Curved
This is a variation of the straight type mentioned above. The only difference is that the rod is curved. Curved curtain rods are ideal for compact bathrooms because the curved profile gives more shower space. The curved lines also look good in vintage, feminine, and eclectic bathrooms.
Adjustable - Straight
Adjustable shower curtain rods offer the benefit of adjustable length. They are not wall-mounted but pivoted. The components include padded pivots or flanges at both the ends of the rod that house tension springs. The rod has slots at its one end. So, if you want to increase its length, you stretch it and let the length-stopper or button slide into the slot that offers desirable length.
To fix the rod to the wall, you move the threads of the tension spring counter-clockwise to move the flange toward the wall. Keep doing this until the flange is securely "locked" and holds firmly on the wall. Finally, snap the covering over the flange, and you are good to go!
These shower curtains are also known as tension rods because of the tension springs used in their locking mechanism.
The main benefit of this design innovation is that they don't need any installation. And you can easily adjust rod height or even move the rod from one shower to the other simply by easing the tension springs and unlocking the rod.
These shower curtain rods are ideal for both shower and tub bath, as they offer height adjustment.
Adjustable - Curved
Everything remains the same as above, except that the rod is curved, so you feel roomier inside the shower. Adjustable shower curtain rods are available in single as well as dual rod options. If you fancy having double curtains, choose this style.
