Hemp

• Hemp makes an effective heavy-duty shower curtain. You can find curtains made from organic hemp, grown without the use of pesticides or fertilizers. Hemp has antifungal properties, so it is naturally resistant to mold and mildew. Because it is slightly absorbent, shower spray is picked up by the hemp fibers rather than running down the inside of the curtain and onto your bathroom floor. The curtain should be left extended to dry.
  
  

Cotton

• Organically-grown cotton is touted as having a low environmental impact. Shower curtains made from cotton are lighter than those made from hemp. You can find shower curtains made from cotton canvas that has been treated to make it more water resistant. Cotton shower curtains are available in a wide range of designs and colors. Choose unbleached cotton or cotton bleached with hydrogen peroxide, which breaks down harmlessly into hydrogen and oxygen in the water system.
  
  

Linen

• Linen is another natural fiber that's making a comeback for green furnishings. Linen is made from the fibrous stems of the flax plant, so it's a renewable resource. You can now find shower curtains made from this fabric.
  
  

Recycled/Recyclable Plastic

• Recycled plastic from various sources can be made into many household items, including shower curtains. You can also find shower curtains made from high-density polyethylene or HDPE. Unlike conventional PVC shower curtains, which can't be recycled because of the toxins they contain, HDPE can be recycled.
  
  

Glass Doors

• Instead of a shower curtain, consider installing a glass door in your shower. Doors let less water out onto the floor and glass isn't subject to mildew. Doors also don't tear or sag.
