Compost toilet on narrow boat

Hi all.

I have recently moved onto a narrow boat/barge and would like to put in a compost toilet. The toilet can be out of doors but space is a premium so any thought about what might work.

I should note there will be two of us male and female so ideally a solution needs to accomdate sitting and standing.

Great to hear any suggestions

There is a joke about a 'poop deck' in here somewhere....

Before this goes off in the wrong direction, are you asking about a self contained unit, like the Chemical/RV toilets; or are you speaking of a biodynamic composter? If the latter, are you going to garden on the barge? Where will the compost be used in your floating paradise?

Nature's Head is a brand of composting toilet designed for sailboats. It needs a little power to run a tiny fan. Works well for two. Cheaper than most commercial composting toilets, but still not cheap.

Lovable loo sawdust buckets are the most compact diy version I can think of.

Bigger question is what do you do with the doo every week or two? Does it have to stay on the barge or do you have a place to compost on land?

Is the boat/barge tied at the same spot all the time? Do you have access to usable shore space for gardening etc?
