One major factor you should consider when purchasing new shower curtains is to ask the salesperson for advice, there are many new fabrics that are now being used and some of these are mildew resistant, this type of material has been chemically treated in the manufacturing process to reduce the growth of mould. If you are looking a natural shower curtain than hemp is what you should choose, this is now becoming more and more available in many different styles and shapes. Hemp shower curtains do require more washing but the overall softer look is well worth it.
