I am using my blue diamond toilet on my narrowboat. I have lived on the canals for 35 years always using a chemical toilet. Having read an article on composting toilets I decided to give it a try. I am very pleased that I did as it is as good if not better than it was cracked up to be, no odours , no chemicals and no emptying in often filthy sanitary stations. I am so glad that I have changed and would recommend it to anyone.
