If you have an old spa pool, you can renovate it or…turn into a cool fishpond! Strip off all the fittings and block all the holes with expanding foam and 2 part epoxy. Dig a big hole, put the pool in the hole and level it (took several attempts). If you don’t get it level it will look awful. At this point you should also put in electrics for the pump. Put wire rebar mesh over the top and brick around it. You can make the fountain from tiles on a wood frame and fill with expanding foam – the tiles are free end of line from a tile warehouse scrap bin. Keep reading the tutorial here.
