Wood Spiral Staircases: All-Wood and Wood-Tread Designs

A wood spiral staircase is a stair whose treads and other visible components use wood as they turn around a center column. The structure can be predominantly solid wood, or it can combine wood with a metal core. Both approaches bring natural grain into a space while using the compact footprint of a spiral stair.

In a solid-wood design, the column, treads, and railing create an all-wood appearance; discreet metal fasteners may still be part of the structure. In a wood-and-metal design, wood treads or sleeves can be paired with a steel column or frame. Paragon offers more than a dozen wood species and options, so the stair can coordinate with existing flooring, trim, or furniture. These stairs are especially well suited to interiors, where the wood is easier to protect from prolonged moisture and weather.

All-Wood or Wood-and-Metal: Which Wood Spiral Staircase Should You Choose?

Choose the construction that gives you the appearance and configuration your room needs. An all-wood stair puts the grain at the center of the design. A wood-and-metal stair can retain much of that warmth while using a metal column or other metal components within the structure.

The Artisan is an example of Paragon’s solid-wood craftsmanship, with hidden steel fasteners in its construction. The Passport has solid-wood sleeves fitted over a steel center column and includes metal railing details. It is a useful example of why a stair’s appearance and its underlying structure are worth comparing separately.

Neither construction is automatically the better choice. Compare the actual product details, intended use, and available options with a designer before deciding.

Wood Species and Finish Options

The species and finish determine whether a wooden spiral staircase blends with the room or becomes its focal point. Paragon lists more than a dozen domestic and exotic species, including lighter choices such as maple, alder, and hickory, and deeper-toned options such as walnut and cherry. Each has its own grain, color, and response to stain or finish.

Wood species and tread options vary by stair model. Our designers can help you confirm what is available for the configuration you choose.

Bring a flooring sample or a photo of nearby millwork to your design consultation. A designer can help you decide whether to match the existing wood closely or choose a deliberate contrast. Explore the current wood options before settling on a species; availability and finish choices depend on the stair model.

Where Do Wood Spiral Stairs Work Best?

Wood spiral stairs work best where their natural finish will be seen and the stair’s compact footprint helps the layout. In a living room, the stair can connect floors without the long run of a straight staircase. In a loft or mezzanine, it can provide access while preserving usable space below. A cabin can use the same form to connect levels and carry the room’s wood palette through the stair; Paragon’s guide to small wood cabin stairs offers more ideas for that setting.

Wood spiral stairs are most often chosen for interiors, where their grain and finish become part of the room’s design. We offer select wood species for outdoor projects, but our warranty does not cover wood stairs or wood parts installed outside. Talk with our designers about your site and maintenance expectations. If you want a warm deck look with lower-maintenance treads, explore the Paragon + Trex® Spiral Stairs Collection, or consider one of our outdoor aluminum or galvanized steel stairs.

How Much Does a Wood Spiral Staircase Cost?

Wood spiral staircase pricing depends on the configuration you choose. Diameter, floor-to-floor height, construction, wood species, tread count, railing details, and finish can all change the quote. A kit such as The Passport and a more extensively crafted solid-wood stair such as The Artisan also serve different design goals, so compare their specifications rather than expecting one price to describe every wood stair.

Are Wood Spiral Staircases Code Compliant?

Yes, a wood spiral staircase can be configured to meet applicable building-code requirements. Compliance depends on its finished dimensions and details, not on whether the visible material is wood or metal. Paragon’s in-house design and engineering teams can help choose a configuration for the stair’s intended use.

For residential projects governed by the 2021 International Residential Code, spiral stairs require at least 26 inches of clear width, at least 6¾ inches of tread depth at the walkline, a rise of no more than 9½ inches, and at least 6 feet 6 inches of headroom. The walkline is the path around the turn where tread depth is measured. Under the 2021 IRC, it is located 12 inches from the inside of the turn, measured from the widest point of the clear stair width at the walking surface. Local code adoption and the authority reviewing the project determine the final requirements, so confirm them before ordering.

Our wood spiral stairs are available in three diameters: 4’6″, 5’2″, and 6’0″. The right size depends on your floor opening, how you’ll use the stair, and the requirements for your project. Our stair designers can confirm the clear walking width and opening needed for the wood model you choose.

How Do You Care for a Wood Spiral Staircase?

Keep an indoor wood spiral staircase clean and dry, and follow the care instructions for its particular finish. Dust and grit can wear a tread surface over time; standing moisture can affect wood and its coating. Inspect high-use treads as the finish ages and ask about refinishing when needed. Paragon’s warranty terms also include specific finishing requirements for interior wood components, so review those instructions when the stair arrives.

Why Choose Paragon for a Wood Spiral Staircase?

Paragon has made stairs since 1947, and its in-house wood shop gives customers a way to choose the species and details that suit their home. A designer can help compare a predominantly solid-wood stair with a wood-and-metal kit, then check the measurements and finish choices before you buy. Paragon’s published warranty distinguishes coverage for wood components from its lifetime coverage for metal fabrication, so you can review the terms that apply to the configuration you select.

Frequently Asked Questions

Are wood spiral staircases a good idea?

Yes, a wood spiral staircase can be a good choice for an interior where you want natural grain and a compact stair footprint. Compare solid-wood and wood-and-metal constructions based on the room, how often the stair will be used, and the look you want.

Can a wood spiral staircase be all wood?

Yes. Paragon offers predominantly solid-wood designs such as The Artisan, although discreet metal fasteners can be part of their construction. Other stairs combine wood with a steel center column or frame; The Passport, for example, has wood sleeves over a steel column.

How much does a wooden spiral staircase cost?

The cost depends on diameter, height, construction, wood species, railing, and finish. A quoted price for one kit will not describe every wooden spiral staircase. Request pricing for the dimensions and options your project requires.

What wood species are available?

Paragon offers more than a dozen wood species. Lighter options listed by Paragon include maple, alder, and hickory; deeper-toned options include walnut and cherry. Ask a designer which species and finishes are available for your selected stair.

Are wood spiral stairs code compliant?

They can be when configured for the applicable requirements. Under the 2021 IRC spiral-stair provisions, the minimum clear width is 26 inches, minimum tread depth at the walkline is 6¾ inches, maximum rise is 9½ inches, and minimum headroom is 6 feet 6 inches. Your local authority determines which code applies.

Can wood spiral stairs be used outdoors?

Yes, we offer select wood species for outdoor projects, but our warranty does not cover wood stairs or wood parts installed outside. For a wood-inspired deck look, consider the Paragon + Trex® Spiral Stairs Collection, which uses composite treads that do not need seasonal sealing or staining. Our designers can help you choose a material for your site.

A wood spiral staircase should fit both your room and the way you plan to use it. Paragon’s designers can help you choose the construction, species, size, and finish. Get Quick Pricing for your project, or explore the options in Build Your Stair.
