I think upcycling small, glass jam jars into hand soap dispensers filled with Dr. Bonner’s liquid soap for the bathroom and kitchen is a great idea. But here’s some other options, like this quick and easy soap dispenser how to from Design Sponge.
Of course I love Mason jars, but I’m not too crazy about the plastic covering. Still, this serves as another option. You can do it yourself via this tutorial from Apartment Therapy or purchase it online at Etsy.
