Shower Curtains are either a necessary item for our bathrooms or just another added piece of decoration, but do we actually need them ? The answer simply put is Yes, shower curtains provide a no nonsense approach to keeping our bathrooms and other wet areas typically clean and dry. They can be used as a decorative piece or alternatively we can use them purely and simply as a functional curtain.
