Twin Chamber Composting Toilet Box


Essentially this is a box made from recycled plastic divided into two compartments, one for current use and one that is resting and composting. There is a urine diverter inside that pipes the liquid into an external 25l container or a soak away, depending on your situation. There are also two large hatches at the back that you empty the compost from. We were asked to design the box for a client who wanted a twin chamber toilet in his timber arc composting toilet.
