One of my personal favorites when it comes to solid stone steps, the Chester County Natural Riser Edge Step is sawed to a 6″ thickness and is 18″-20″ deep. Lengths range from 3′ to 8′. Get the best of both worlds with the look of the natural riser edge combined with the consistency of a sawn and thermal finished stepping surface. These are a great addition to any landscape design, rustic yet refined.
