Soap on a Rope
If you are concerned about using too much plastic you can substitute your shower gel for a soap on a rope.
Gone are those days of trying to find the soap you have dropped in the shower base, just put the soap on a rope around your wrist. When you have finished your shower just hang the soap up "no more soggy soap".
These soaps are made using the cold process method and contain essential oils to leave your skin moisturised.
