Just emptied the wee bottles of both composting toilets. Second time this holiday. So we seem to be pretty consistent at filling 2 bottles a week. Not had to empty either toilet of solids and they are nowhere near full. We don’t tend to use the clubhouse toilets very much. A reasonable picture of a week at anchor or while sailing.
Just to remember that emptying a composting toilet is quick, clean and easy. The wee bottles just pour down a normal toilet with no mess.
