How to Build an Easy Water Fountain

What you need
Adult supervision required, decorative items like marbles or twigs, pebbles or decorative stones, potting soil or plant moss, scissors or small trowel, shallow container or bowl, small submersible pump with tubing, small water friendly plants, water

Step 1

Gather all the materials and place them on a clear table or tray so everything is easy to reach.

Step 2

Rinse the container with water to make it clean and then dry the rim and outer parts with a towel.

Step 3

Put the pump into the container and set it on one side where it will sit stably.

Step 4

Attach the tubing to the pump and run the tubing up toward the top edge where the water will pour out.

Step 5

Pour a layer of pebbles into the bottom of the container to hide the pump base and make a rocky bed.

Step 6

Tuck the plant roots into the pebbles and add a little potting soil or moss around them to hold them steady.

Step 7

Arrange decorative items like marbles twigs or small figurines around the plants to make your mini scene.

Step 8

Slowly pour water into the container until the pump is at least halfway submerged so it can pump safely.

Step 9

Ask an adult to plug in the pump and turn it on while you stand back and watch the water start to move.

Step 10

Watch how the water flows over the stones and around the plants and think about places you might shift a stone to change the flow.

Step 11

With an adult’s help turn the pump off when you are done experimenting for now.

Step 12

Take a photo and share your finished tabletop water feature on DIY.org

Help!?

What can I use if I don't have the submersible pump and tubing listed in the materials?

Use a small battery-powered or USB aquarium fountain pump or a ready-made tabletop fountain kit so you can still follow the step 'Attach the tubing to the pump' and run water to the container edge.

Why might the water not flow when I plug in the pump and how can I fix it?

If water doesn't flow, double-check the instruction to have the pump at least halfway submerged, make sure the pump sits stably on one side, and straighten or reattach the tubing to remove kinks and trapped air.

How can I adapt this activity for younger or older kids?

For younger children, focus on rinsing the container, pouring pebbles, tucking plant roots, and arranging decorations while an adult handles plugging in the pump, and for older kids let them handle 'Attach the tubing to the pump', adjust flow paths, and experiment with different plant placements.

How can we extend or personalize the tabletop water feature after finishing the basic build?

Personalize it by adding waterproof LED lights under the pebbles, swapping in different stones or moss during the 'Pour a layer of pebbles' step to change flow patterns, or placing tiny figurines and moving stones to study how the water path changes before taking your photo.

Facts about indoor water features and container gardening

☀️ Evaporation can lower a fountain's water level quickly in warm or sunny spots, so tabletop features usually need a top-up every few days.

⚙️ Submersible pumps are rated in gallons per hour (GPH) or liters per hour (LPH); tiny tabletop pumps are often around 50–200 GPH (190–760 LPH).

🪨 River stones and pebbles change the sound of water — larger stones produce deeper, softer flows while tiny pebbles make bright, tinkling splashes.

💧 Small tabletop fountains recirculate the same water, so a cup or two can run them for many hours without needing a huge reservoir.

🌿 Some hardy plants like pothos, peace lilies, and lucky bamboo can grow with roots in water and help absorb impurities.

How do I build a small tabletop water feature?

To build a tabletop water feature, pick a waterproof container and a small submersible pump sized for the container. Arrange the pump and hide tubing under stones or a false base, then add pebbles, larger stones to guide flow, and suitable plants. Fill with water to the pump’s recommended level, plug in and test flow, adjusting stones for desired sound. Finish with decorations. Always work with adult supervision during assembly and testing.

What materials do I need to build a tabletop water feature?

You'll need a waterproof container or shallow basin, a small submersible pump with USB or low-voltage plug, tubing (if required), a variety of stones and pebbles, water-safe adhesive or silicone (optional), aquatic or moisture-loving plants (small ferns, pothos cuttings), a bucket for filling, towels, and decorative items like figurines or driftwood. Also have tools like scissors or pliers and a GFCI-protected outlet for safer power use.

What ages is this activity suitable for?

This activity suits a range of ages: preschoolers (4–6) can help choose stones and plants and watch water with close adult guidance; elementary-age children (7–11) can assist assembling; older children and teens can set up pumps and design layouts with supervision. Electrical and water safety means an adult should handle pump installation and power. Adjust complexity based on attention span and fine motor skills.

What safety tips should I follow when building a tabletop water feature?

Safety tips: always supervise children near water, use a low-voltage pump and plug it into a GFCI outlet, keep cords dry and fastened away from edges, and place the feature on a stable surface. Use aquarium-safe materials and avoid small loose parts for toddlers. Regularly change water to prevent mold and check for leaks. Teach children not to touch plugs or open electrical connections. If unsure, seek adult help for wiring.
