Our Stairway Waterfall is made with the same high-quality cast concrete material as our other waterfalls. The easy installation sets it apart. As the name says, it is just one piece! Weighing in at up to 300 pounds, it’s very stable once secured in place. A large access panel on the back allows for easy plumbing access. All this makes the Stairway waterfall very do-it-yourself friendly – no mortar needed.
