They are sometimes made of cloth but are mostly found in plastic or vinyl materials. Apart from adding style, they give those showering privacy while preventing water from spraying into the other areas of the bathroom. With installation very easy, many people often have two curtains fitted. The inside curtain being mainly for function and the outer one for style.
