I know there is debate over various toilet systems and which is best / awful but after searching I cant seem to find the answer I am looking. Long story short, I am in the process of moving onto a narrowboat, using it as a liveaboard. It currently has a dump through pump out toilet system (system has a few issues, potentially leaking tank ) I want to remove this system and replace with a composting toilet, something like the nature's head most likely. Does anyone here have any experience removing these systems. In my head I think I should be able to get the holding tank clean(ish), seal up the hole from the WC and then leave it vented and in situ. As the composting toilet requires no plumbing it can sit where the pump out toilet used to sit.
Tank is steel construction, not sure if it is integrated into the hull or not. It would require a considerable about of deconstruction particularly of the bathroom and floor to remove the tank. Any thoughts? suggestions? or input? Many thanks
