A beautiful custom-design spiral staircase can be installed in your home in a matter of a few hours.

How to Install a Spiral Staircase

A step-by-step illustration of how a custom spiral staircase gets installed.


The client was building a new game room in the basement of their Saratoga, CA, home. They needed a spiral staircase to accent the basement because the space is very narrow, but they also wanted something that was unique and attractive.


European Cabinets & Design Studios suggested the K8 Jazz collection by CAST, a stainless steel spiral staircase with the solid wood steps in Wenge, with a stainless steel protective edge. Starphire Ultra-Clear Glass was used in the guardrail.


The staircase was custom-designed by ECDS, manufactured in Italy by CAST, and assembled in the client’s home.

Step 2: The main steel pole is attached to the floor with bolts and aligned with the landing step.
