Crestanks WonderLoo

The WonderLoo is constructed with a plastic pipe for urine separation and a 22 L bucket for storing faeces accompanies the Wonderloo. The plastic bucket is placed inside the WonderLoo and lifted out to empty when it is full. The urine pipe is lead to a separate storage container.

The Crestank products are manufactured to require minimal maintenance. Installation instructions and product schematics are offered by the manufacturer.

The lifetime of the WonderLoo is estimated at 5-10 years, with the replacable plastic seat as the part that is most likely to get worn out first.^{Interview with manufacturer}

Separation of urine and faeces makes handling the waste easier and reduces the risk of contact with pathogens. Since the bucket has to be lifted out of the toilet there is a risk for contact with the excreta.
