How to Make a Cardboard Fountain

Updated February 21, 2017

A water fountain brings the soothing sound of running water into the home. However, buying water fountains from speciality websites or stores can prove to be quite costly. A water fountain can be built from any container that will hold water, even a waterproofed cardboard box. With a few materials and a little spare time, you can build a cardboard box water fountain to display in your home.

  1. Use the scissors to cut the sides of the cardboard box down to 4 inches high. This will allow the fountain to be easily viewed without being obstructed by the high walls of a cardboard box.

  2. Use the paintbrush to generously coat the entire surface inside the cardboard box with the fibreglass resin. This will waterproof the cardboard so the water does not penetrate it.

  3. Allow the fibreglass resin to dry for the time specified by the manufacturer.

  4. Place the water pump in the centre of the cardboard box and position the cord to extend out the back of the water fountain.

  5. Connect the plastic tubing to the water pump. On most standard water pumps there is a small plastic valve at the top of the unit to which plastic tubing is connected. The pump sucks in water from a filter on the bottom of the unit and expels it through this valve on the top of the pump. The plastic tube will direct the water to flow over your river rocks in the fountain.

  6. Fill the water fountain with river rocks. Position the rocks around the plastic tubing so that it extends directly upwards, through the middle of the rocks. Use your scissors to cut any excess plastic tubing that is exposed; the very end of the plastic tube should barely be visible through the rocks.

  7. Fill the fountain with water, stopping when the water level is 1 inch from the top of the river rocks.

  8. Plug in the water pump and enjoy your cardboard fountain.

  9. Tip

    To decorate your cardboard water fountain, consider buying some acrylic paints and painting the outside of the box. Craft items such glitter and beads can be glued to the cardboard exterior of the fountain for added ornamentation.


    Never plug the water pump in without water in the fountain, as this will damage or break the pump.
