The two inches of space between the curtain and floor prevents the bottom of the curtain from collecting too much moisture and dirt.
A tension rod is not fixed permanently to the walls. It is held in place by a strong spring inside the rod, which applies enough pressure on the walls to hold it in place. [4] X Research source Twisting clockwise will shorten the curtain rod.
In general, tension rods can be adjusted to fit the width of most spaces without requiring any measurement beforehand. [5] X Research source If you do want to measure beforehand, the rod’s final length should be approximately 1 inch longer than the space it will occupy to maintain a snug fit.
The more you have to lengthen the tension rod to fit in place, the less stable its hold will be. If your rod is unable to maintain a strong hold, you probably need to get a longer tension rod.
Tweak slightly to make it straight, if necessary.
If you have dry wall you will need to use anchors with your brackets. Learn more about using dry wall anchors here.
These also come in ring form. The rings snap open and closed easily. Unsnap to open them, hang them on the rod, but do not snap them closed them yet. Once you have the hooks/rings on the rod, make sure that they fit properly and slide easily along the curtain rod. Most come in standard sizes that fit most curtain holes and rods, but if you’re using hooks/rings that are very large or very small, you may want to measure the size of the holes before you buy rings to make sure they will fit.

Liners are usually clear plastic and they act as a barrier between the shower and the curtain. Liners aren’t required, but they are practical and commonly used, especially with shower curtains that are made of fabric that isn’t waterproof.
If you are using curtain rings, snap each ring closed after you thread it through. Double check that the liner is on the wet side of the shower and the curtain is on the dry side, facing out into the bathroom.
If the rod cannot support the weight, you may need to get a longer or more sturdily built tension rod. If the curtain and liner aren’t sliding easily down the rod, you may need bigger hooks/rings to properly fit the rod.
