Water fountains give you a sense of tranquility. There is not anything more soothing or relaxing. The sound of water flowing, like the sound a mountain stream, can alleviate your stress and put you to sleep. It can also drown out unwanted sounds, like cars on the road or planes overhead.
Imagine that after a long day, you open your front door and voila, immersion into the calming sights and sounds of a beautiful fountain in your front hallway. Alternatively, you step out into your backyard, and there sits a beautiful piece of art with soothing sounds and the perfect sight for your tired eyes.
