Alice And The WonderCat

Thank you for this and all suggestions, I will look at everything There are for sure some great advices from others as well. Thanks for all feedback, even if now I am not sure I will ever ask any more questions around here... You are probably happy about that. Original question was not "does it worth it" or "should I do this" but how and how much, as I am 100% sure living with someone else old sewerage under my deck is out of the question. Especially when I am used to reusing grey water in the garden or doing outside cleaning with it. I cannot use metal tanks or pipes because of personal reasons. If it's offensive to someone, I am sorry, I did not meant to offend your metal tanks. They are great for sure, just not for me. Wish you all great Sunday

Hi All :) I am planning to buy narrowboat and making my budget predictions. I know that most of older boats have nonplastic water tanks, black water tanks and sewer tanks. I would like to take out all of them and put in only plastic black water tank and fresh water tank (as composting toilet is my choice). How much of the flooring I will be in need of removing to do that? I am ready to remove as much as needed (I am planning to put new insulation and wooden floors, so that's not a problem). Maybe someone has experience with this kind of project and could give me some advice? I could not find any articles or YouTube videos on that... Thank you :)
