To start building your indoor water fountains, place the pump in the bottom of the container with the tubing attached and the switch on. Fill around and above it with bricks or stones.

Create a ledge with a flat stone for a mini waterfall. Adjust the flow with the valve and orient the water line until you achieve a pleasing result. Hide the line with more stones

Indoor Water Features

Create this natural indoor water fountain using a planter, rocks and a small pond pump.

Plug the drain hole of a large glazed ceramic or resin planter with plumber’s epoxy putty. After it cures, fill the planter with water for a day or two to confirm that it won’t leak. Place the planter exactly where you want it before adding the rocks and water. It’ll be very heavy once it’s done.

Stack bricks or stones around and above a small pond pump (about 40 gph) to about two-thirds the depth of the vessel. Then cut the water line to length and add a restrictor valve. We used a 3/8-in. PEX valve (clamp it if the hose comes loose under pressure). Or choose a “pinch”-type valve, found with pond accessories at home centers. You can change the look and sound of the indoor water fountains by tinkering with the water flow rate and the shape, size and arrangement of your stones. That’s the fun part!
