I am very interested to hear from people who have a composting toilet. My issue is that I am getting older and am working out ways to ensure I stay living on my boat. If I get a bit infirm carrying my Thetford to the dispaosal may prove difficult. Kind neighbours have offered to do the job but that IS NOT ACCEPTABLE. Filling my water tank etc is but not dealing with my s..t ! I have friends with gardens who would happily compost it for the required amount of time then use it on their flower beds (not recommended for vegetables I believe). As it will probably cost about £700, including the installation with the ventilator I would value peoples experience with them.
