Curved Staircases

Acadia Stairs specializes in a wide variety of modern, custom curved staircases. Using a blend of style and function, our custom staircase designs can fit into any home. Curved staircases feature a helical or spiral design without the center pole that are found in spiral staircases. They have a very tight inner radius, as small as a few inches, with inner handrails for extra support.

When working with our team to design your custom curved staircase, here are a few key features that our curved style has to offer:

  • A wide variety of materials including wood, stainless steel, stone, glass, and more



  • Single stringer, double stringer, or side stringer designs (see below)


  • An inner radius of 24″ to 36″
  • A tread run with a narrow edge of 6″


  • A consistent inner curve for the best traffic pattern



  • A 10-foot or wider outer radius

Single Stringer
