If you are looking to capture some of the breezy outdoors in your home, adding an indoor waterfall is just the thing. An indoor fountain will also give any room an aesthetic focal point, incorporating modern design with a typical outdoor feature. When installing an indoor waterfall fountain, you have the choice between buying one that is already made and building it yourself. Indoor waterfalls come in a variety of materials including slate, copper, marble and stone. If you are looking for a low cost, simple waterfall, then building it yourself is the best option.

Step 1 - Choose a Basin

Before you can select the size and style of basin you want to use for your base, you will need to know the flow rate of the water pump you will be using. This flow rate will determine the minimum water amount that is needed at all times to keep the water flowing through the pump. Once you know this you can choose a basin that is deep enough to hold a bit more than the required volume needed for the pump.

Step 2 - Set it Up

Place the pond liner along the bottom of the basin. Since you will be adding water, make sure both the basin and plastic are waterproof. For best results, use outdoor pond lining. Following the manufacturer’s instructions, place the water pump in. If it is a dry pump, it will be placed outside of the basin, towards the back to hide it from view. Make sure the basin you choose is deep enough that the pump isn’t sticking out or showing.

Step 3 - Build Waterfall

Set the sheet plastic into the basin, mounting it either vertically or on an angle, depending on the desired look. If you angle the waterfall, the water will fall slower than a straight, vertical waterfall. If you find the water flows too fast either way, you can always opt to cover your waterfall in a plastic that can be shaped into a bumpy surface, creating some resistance for the water.

Secure it to the side of the basin using waterproof glue. Run the plastic pump tubing up the back of the sheet plastic, placing it discreetly. For a slightly different look, you can use a metal sheet instead of the plastic or mirrored waterfall back. For a tiled look, you can use a piece of glass with crafting tiles attached.

Step 4 - Finishing Touches

Once you have secured the actual waterfall and placed the piping, you can add stones, decorative marbles or rocks, filling the basin. If you placed the sheet plastic on an angle, you can also add stones and rocks, building up from the base, using larger rocks or stones at the base. If the sheet plastic is vertical, you can glue small stones or rocks to it using waterproof glue. If you have children or animals that may get into your indoor waterfall fountain, make sure to use a non toxic glue.
