I have seen a fountain in a catalog that I just love and think it is doable in hypertufa...since the hypertufa may not be water tight I thought I could line the reservoir with a plastic pan, as it wouldn't show. The part I'm wondering about is the weight...the one in the catalog weighs 350 pounds! Does anyone know about how much the same size would weigh in hyper? The cost on the fountain is $650.00 and who knows how much shipping charge!!
