Now turn your tub into a shower by surrounding it with a circular shower rod and curtain

Round shower curtain rods can be used in any location. These simple curtain rods offer you the advantage of having a very inexpensive shower stall, as the curtain acts as your water barrier all around the shower. If you have a bathtub which is not directly against a wall you can now turn it into a shower simply by equipping it with a circular shower curtain rod and adding a shower head.  The main advantage of having a shower with a circular shower curtain rod is that it is inexpensive, can be placed anywhere there is a floor drain, and the look can easily be changed just by changing your shower curtain.

When using a round curtain rod, you would normally not have any structural walls to worry about. Generally, these circular shower rods are supported by bars coming down from the ceiling although support struts coming from the wall can also be used.  These types of rods come in brass, stainless steel, nickel or bronze metal finishes. Depending on the type of hoop shower curtain rod you get, will depend on the number of ceiling supports you should use.
