Cost of a spiral staircase by material
Spiral staircase prices depend mostly on the material. Steel and wrought iron spiral staircases typically cost the least, while wood, glass, and aluminum cost the most. You can also mix and match different materials for the railing and treads.
Many spiral staircases come in a prefabricated kit that you can either install yourself or hire a professional to install for you. Custom stairs and high-end materials cost much more than average.
| Staircase material | Average material prices | Average total installed cost |
|---|---|---|
| Steel | $1,000 – $5,000 | $1,300 – $6,000 |
| Wrought iron | $1,000 – $5,000 | $1,300 – $6,000 |
| Wood | $2,000 – $14,000 | $2,500 – $18,000 |
| Aluminum | $2,000 – $18,000 | $2,500 – $20,000 |
| Glass | $5,000 – $15,000 | $5,500 – $20,000 |
| Composite | $3,500 – $6,000 | $4,000 – $8,000 |
Steel
Steel spiral staircases cost $1,300 to $6,000 installed on average. Steel is the most common metal staircase material because it’s strong, affordable, and durable. Steel spiral staircases are often sold as kits in various different styles. Some kits have wood treads with a steel frame.
Wrought iron
Cast iron and wrought iron spiral stairs cost $1,300 to $6,000 installed. This is a popular material because of its durability and Victorian appearance. The style and design will determine the final price. This material is best suited for an indoor spiral staircase since it may rust outside.
Wood
Wood spiral staircases cost anywhere from $2,500 to $18,000 with installation. Softer woods like oak and pine cost less, while high-end woods like walnut and mahogany cost more. Wood spiral staircases are relatively rare and are often custom-built, so they cost a lot more than pre-made metal kits.
Aluminum
Aluminum spiral staircases are a little harder to find and cost $2,500 to $20,000 installed. This material works well indoors but is particularly good for exterior spaces because it’s weather-resistant. If you live near an ocean or in a humid climate, aluminum may last longer than other materials.
Glass
A glass spiral staircase costs $5,500 to $25,000. Glass staircases are sleek, modern, and won't block your view, but they’re harder and more expensive to build. Most installers incorporate wood or metal materials into the design, specifically in the railings, balusters, and supports.
If you want the sophistication of glass but can’t afford a whole new staircase, you can add a glass railing to an existing staircase.
Composite
A composite spiral staircase costs $4,000 to $8,000 installed on average. This material is typically used for outdoor stairs because it’s low maintenance, durable, and longer lasting than wood. You can easily clean composite stairs with soap and water, whether they’re indoors or outdoors.
Outdoor spiral staircase cost
The cost of an exterior spiral staircase depends on the material, the number of stairs, and whether you need to add a new landing pad. The best materials for outdoor stairs are wood, aluminum, or composite. Steel and wrought iron aren’t as weather-resistant, and glass is more easily damaged.
Related exterior projects include:
Outdoor porch or deck railing costs $20 to $60 per linear foot for wood, composite, or vinyl. Other railing materials cost more:
Wrought iron railing costs $65 to $135 per linear foot.
Glass railing costs $150 to $600 per linear foot.
Cable railings cost $75 to $285 per linear foot, depending on the post material.
Deck repairs cost $100 to $750 for simple repairs and $750 to $2,500+ for extensive ones.
Spiral staircase cost factors
Factors that affect spiral stair installation costs include:
Prefab vs. custom: Premade stair kits cost less and are easier to install. Custom staircase projects cost more and take longer to complete.
Size: The average size of a spiral staircase is 8 to 9 feet tall and 3 to 5 feet wide. Longer staircases cost about $150 to $300 per step.
Location: Costs vary depending on how much space you have and if the contractor needs to do any demolition work. Cutting into drywall or reinforcing floors will affect the price.
Removal: Removing and disposing of an old staircase may cost $500 to $2,000.
Repairs: Staircase repairs cost about $100 to $1,000, depending on the scope of the damage.
Railing: Stair railings and balusters cost $20 to $250 per linear foot or $500 to $6,300 total, depending on the material. The railing, also called a banister or handrail, is what you hold onto when walking on stairs. It’s supported by vertical rods called balusters.
Compared to spiral staircases, a standard staircase costs $500 to $2,000 for exterior stairs or $2,000 to $5,000 for a main interior staircase.
Labor
The labor cost to install a spiral staircase is $60 to $140 per hour, depending on the project complexity, material, and the type of professional you hire. Basic staircase kits take less than a day to install, while custom designs may take 1 to 2 weeks to complete. Other contractors have different rates:
A general contractor charges $50 to $150 per hour or 10% to 20% of the total construction costs.
A carpenter charges $30 to $100. A master carpenter charges $100 to $200 per hour.
A handyman charges $50 to $80 per hour.
Spiral staircase FAQs
How long does it take to install a spiral staircase?
Installing a spiral staircase can take anywhere from 1 to 5 hours for a simple premade kit to 1 to 2 weeks for a custom design.
How do I know if I need a new staircase?
You may need to remodel or replace your staircase if you notice any of the following signs of aging or damage:
Loose railings or balusters
Squeaky or damaged treads
Sagging stairs
Water damage
Unsteady posts
Are spiral staircases safe?
Spiral staircases are just as safe as any other kind of stairs, especially when installed properly by a professional. However, they are more difficult for people with mobility issues to climb because they’re steeper and narrower than average.
Can I build a do-it-yourself spiral staircase?
If you have previous experience with similar DIY projects, you may be able to handle assembling a spiral staircase kit. However, if you’re not confident in your abilities, consider at least hiring a handyperson to make sure the staircase attaches properly to avoid accidents or injuries in the future.
