The Separett Villa 9000s are installed in two wet rooms we have built next to our yurt and Shepherd’s Hut. They are a great success for our situation and there are never any smells coming from the toilet, bearing in mind the doors to the wet room are kept closed. I have a notice in front of the toilets on how to use them properly and they are very easy to keep clean. I would recommend using the green bio bags and a hot composting bin, the easiest way of disposing of the bags of waste.
