Tension shower curtain rods are fixed to the wall or ceiling above the bathtub around the shower unit to support the shower curtain.
They are usually attached to wall by brackets, which are screwed into the wall and then the shower rail slots into the brackets.
Tension shower curtain rods are available in different styles such as L-shape which are designed to fit around a corner shower unit over the bath tub, curved shower curtain rods, designed to curve out over the edge of the tub creating more space inside the shower area.
These tension shower curtain rods are available in finishes such as brass, nickel, chrome or gold. The cheapest option is plastic, which also has the advantage of being very light.
