The supporting structure of this staircase is hidden inside its body. In closed spaces, such as a basement, a closed rise waterfall stair can be used. Waterfall stairs are comprised of a straight structure mounted underneath and wood top which folds in a zig-zag pattern. The stringers are hidden inside the under mount structure, which is typically painted the same color as the surrounding wall to accentuate its zig-zag design.

Advantages of Waterfall Staircases:

·    Self-contained staircase for a cleaner look.

·    Able to use open or closed rise stairs.
