This aesthetically pleasing fountain resembles a waterfall combined with a privacy screen. Tall, modern, and sleek, this project makes a great focal point or accent piece. By utilizing a sturdy frame, a moderately powerful pump, and a piece of semi-clear plastic paneling, you can create an impressive wall fountain. Of all the entries on this list, this fountain is the most time-consuming and involved, but you cannot argue with the results. There are also several variations of this fountain, some with a standing wall of rocks, others with just the frame and free-falling water. Whichever variation you choose, you won’t regret this impressive outdoor water wall. One of our favorite versions of this fountain added a series of outdoor, waterproof lights to the back of the wall. These lights, when turned on, create a scintillating array of colors as the beams hit the water.
