What is the price of a 12 foot iron staircase?

A 12-foot iron staircase typically costs about $6,000 to $20,000 installed, depending on design, finish, and site conditions. A simple straight run sits near the low end, while custom railings and decorative details push the price higher.

The term “12 foot” can mean the floor-to-floor height or the horizontal length, so confirm which one your quote uses. A 12-foot rise needs about 18 to 19 steps, and that number drives material and labor costs.

Several factors affect the price:

• Design, such as straight, L-shaped, or curved layouts

• Material, since many “iron” staircases are actually mild steel

• Railing style and tread material

• Finish, like powder coating or galvanizing

• Structural support, delivery, and installation access

Galvanized steel can improve rust resistance for outdoor stairs, as covered in our galvanized steel staircases article. If you want a modern look with a higher budget, see our cantilever staircase guide.
