Hardwood Staircase Cost by Species
Species selection is the largest variable in tread and riser material cost. The table below shows per board foot pricing, Janka hardness, and best uses for the most common staircase species.
| Species | Cost/BF | Tier |
|---|---|---|
| Poplar | $2 to $4 | Budget |
| Hard Maple | $5 to $9 | Mid-range |
| White Ash | $5 to $9 | Mid-range |
| White Oak | $8 to $14 | Mid-range |
| Cherry | $9 to $15 | Mid-range |
| Walnut | $14 to $22 | Premium |
White oak: the modern staircase standard
White oak has become the dominant species for custom staircases in contemporary and transitional homes, mirroring its popularity in hardwood flooring. A 48-inch wide white oak tread at 11.5 inch depth and 1.75 inch thickness requires approximately 6.4 board feet and costs $51 to $90 per tread in rough lumber. A 12-step flight (13 treads) runs $660 to $1,170 in white oak tread lumber before milling. White oak takes oil-wax finishes like Rubio Monocoat exceptionally well and matches white oak floors for a seamless transition. See wood stair treads cost for tread-only pricing.
Walnut: the premium statement staircase
Walnut delivers the richest natural finish and the most dramatic portfolio photographs of any domestic hardwood. A walnut tread at the same dimensions runs $90 to $140 each in lumber. A 13-tread floating walnut staircase carries $1,170 to $1,820 in tread lumber alone before the mono-stringer, railing, and labor. Walnut's rich chocolate color darkens beautifully with an oil-wax finish and requires no stain. Book-matched walnut treads cut from the same slab add another $800 to $2,000 to the material cost but create a portfolio-worthy result. See walnut slab prices for current slab pricing.
Staircase Styles Explained
Closed riser, conventional stringers
$4,800 to $8,500
The traditional staircase with solid vertical risers between treads and side stringers carrying the load. Standard residential construction. Most economical for custom work because pre-cut stringer stock is available from lumber yards. Best for painted or semi-painted finishes with poplar or MDF risers.
Open riser, conventional stringers
$9,000 to $15,500
Risers are eliminated, leaving visible space between each tread. Side stringers remain. Gives a lighter, more contemporary look without the cost of a custom steel stringer. White oak and walnut treads float visually over the stringer structure. Popular in transitional and modern renovations as an upgrade from carpet-covered conventional stairs.
Floating, mono-stringer
$17,500 to $38,000
A central steel stringer concealed inside the wall carries all tread loads through cantilevered tread brackets. The treads appear to float unsupported. Requires a structural engineer sign-off in most jurisdictions, a custom steel fabricator for the stringer, and precise framing. The most labor-intensive custom staircase type. Dramatic visual impact for open floor plan homes.
L-shaped or U-shaped with landing
$16,500 to $38,000
A staircase that turns 90 or 180 degrees at a landing platform. The turn adds a landing newel post, landing platform framing, and an angle cut at the rail transition point. L-shaped open-riser stairs in white oak run $16,500 to $28,000 for a 24-step flight. U-shaped (switchback) designs with two flights are priced roughly as two separate straight flights with a shared landing.
What Drives Custom Staircase Costs
Floating vs conventional design
High impactThe single largest cost driver is whether the design is floating (mono-stringer) or conventional (side stringers). A floating staircase requires a custom-fabricated steel stringer ($2,500 to $5,500) that a conventional open-riser stair does not. That structural steel cost alone often doubles the total project price. Floating staircases also require more precise installation, more layout time, and frequently a structural engineer's stamp, adding $500 to $1,500 to project costs.
Wood species
High impactSwitching from painted poplar to white oak on a 12-step flight adds $1,500 to $2,500 in materials and 4 to 8 additional labor hours for grain selection, milling, and sanding. Moving from white oak to walnut adds another $1,200 to $2,000. A premium species selection on a full staircase can add $3,000 to $6,000 compared to a painted softwood build. Species choice often follows the flooring: white oak stairs for white oak floors, walnut for walnut floors.
Number of steps and staircase length
High impactA standard 12-step residential flight (9-foot floor-to-floor height) is the baseline in all pricing above. Each additional 4 steps roughly adds $3,000 to $6,000 to a conventional open-riser stair and $5,000 to $9,000 to a floating staircase due to additional treads, extended steel stringer, additional railing sections, and proportionally more labor.
Railing type and design
High impactThe railing system is often 25 to 40 percent of the total staircase cost. A hardwood railing with turned balusters and craftsman newel posts adds $2,500 to $5,500 to a 12-step flight. A cable railing system adds $1,800 to $3,500. A frameless glass panel railing adds $2,500 to $5,000 or more. A simple wall-mounted hardwood handrail (no balusters) adds $800 to $1,800. Railing design should be budgeted separately when quoting. See the wood stair railing cost guide for detailed railing pricing by species and configuration.
Tread width
Medium impactStandard residential treads are 36 to 42 inches wide. A wide staircase at 48 to 60 inches wide requires wider tread blanks or glued-up panels, which increases both material cost and fabrication time. A 48-inch wide tread requires more board feet than a 36-inch wide tread of the same depth, adding 15 to 25 percent to tread material cost per step.
Site conditions and access
Medium impactReplacing an existing staircase requires demolition of the old structure ($400 to $1,200 for a 12-step flight) and often reveals subfloor patching needed where old stringers attached. Installing a floating staircase in an existing home may require opening walls to access the framing for stringer attachment, adding $800 to $2,500 in framing and drywall repair. New construction installations without existing stairs or finished drywall are significantly easier and faster.
How to Price a Custom Staircase
Staircase projects are the most complex pricing challenge in custom woodworking because they combine structural carpentry, millwork fabrication, and finish work. A line-item approach prevents underpricing.
Determine the staircase type and count every component
Start by establishing the staircase configuration: straight, L-shaped, or U-shaped; conventional with stringers, open riser, or floating. Count the number of steps (typical residential flight: 12 to 16 steps). Measure total rise and run to confirm tread depth and riser height meet code (typically 7-3/4 inch max riser, 10 inch min tread depth). For floating staircases, measure the wall structure to determine stringer attachment points and confirm the framing can handle the cantilever load. Identify all components: treads, risers (if closed), stringers, newel posts, balusters or cables, handrail, landing nosing, and any wall trim.
Price materials by component
Treads are the largest material cost on hardwood staircases. Price each tread at the width, depth, and thickness required (typical: 48 to 52 in wide, 11.5 in deep, 1.5 to 2 in thick). Calculate board feet and price at your supplier's rate for the species selected. For floating staircases, get a quote from a metal fabricator for the mono-stringer (typically $2,500 to $5,500 for a 12-step flight in 6x4 HSS or custom plate). Price railing hardware separately (cable kits at $600 to $1,500, glass panels at $800 to $2,500, or hardwood railing at $900 to $4,000). Add 15 to 20 percent markup on all materials.
Estimate labor by phase
Break staircase labor into phases: shop fabrication (tread milling, nosing profiles, riser panels if applicable: 8 to 20 hours), structural work (stringer installation or mono-stringer setting: 4 to 12 hours), tread installation and scribing to walls (6 to 16 hours), railing installation (6 to 20 hours depending on type), and finishing (4 to 12 hours). A conventional 12-step straight flight with painted poplar takes 30 to 50 total hours. A floating white oak staircase takes 55 to 80 hours. Multiply by your shop rate ($75 to $120 per hour).
Add overhead
Staircase work involves significant site time and often requires multiple visits for rough-in, tread installation, and finishing. Apply overhead at 20 to 25 percent of total labor cost to cover shop rent, insurance, vehicle expenses, tools, and administrative costs. If you are subcontracting the steel stringer fabrication, mark up that subcontract cost by 15 to 25 percent to cover your coordination, scheduling, and warranty responsibility.
Apply your profit margin
After totaling materials, labor, and overhead, apply a profit margin of 25 to 35 percent. Custom staircases are high-value, highly visible projects that command premium pricing.

Start a Staircase QuoteFrequently Asked Questions
- How much does a custom staircase cost?
- A custom wood staircase for a standard 12-step straight flight typically costs $5,000 to $22,000 depending on style, species, and whether the design is conventional or floating. A painted poplar closed-riser staircase runs $4,800 to $8,500. A white oak open-riser staircase runs $9,000 to $16,000. A floating mono-stringer staircase in white oak or walnut runs $15,000 to $35,000 or more. These prices include custom shop fabrication, materials, and installation.
- How much does a floating staircase cost?
- A floating staircase typically costs $15,000 to $40,000 for a 12-step flight depending on tread species, stringer material, and railing design. The steel mono-stringer alone costs $2,500 to $6,000 fabricated and powder coated. White oak floating treads for 13 steps add $2,000 to $3,500. A cable or glass railing adds $1,500 to $4,000. Labor for layout, installation, and finishing runs 55 to 80 hours. Premium walnut floating staircases with glass panels and bookmatched treads can reach $50,000 or more.
- What is the best wood for a custom staircase?
- White oak is the most popular species for custom staircases in contemporary and transitional homes because it pairs naturally with white oak flooring, takes oil-wax and water-based finishes beautifully, and has a Janka hardness of 1,290 that resists tread wear. Walnut delivers the richest natural dark tone and photographs exceptionally well for portfolio work. Hard maple is the hardest domestic hardwood (Janka 1,450) and the best choice where durability is the top priority. Poplar and paint-grade maple are the standards for painted staircases.
- How long does it take to build a custom staircase?
- A conventional closed-riser staircase with pre-cut stringers takes 30 to 50 shop and install hours for a 12-step flight. An open-riser staircase with hardwood treads and a railing takes 40 to 65 hours. A floating mono-stringer staircase requires the most time: 55 to 80 hours for fabrication, stringer installation, tread fitting, and finishing. Complex curved or helical staircases can take 100 to 200 hours or more. Staircase work moves slowly because each tread must be individually scribed and fitted.
- What is a fair shop rate for custom staircase work?
- A fair shop rate for custom staircase fabrication and installation is $75 to $120 per hour. Staircase work is skilled millwork that requires precise layout, angle cuts, and scribing to finished walls and floors. Most woodworkers in mid-sized markets charge $80 to $100 per hour. Urban and high-cost markets support $110 to $130 per hour. Your rate should cover wages, shop overhead, tool maintenance, vehicle and fuel for site work, and a reasonable profit. Floating staircase work often commands a 10 to 15 percent premium over conventional staircase rates because it requires more precise layout and a higher tolerance for error.
- What is the difference between a floating staircase and an open riser staircase?
- An open riser staircase simply omits the vertical riser boards between treads, giving a light, airy appearance while still using conventional side stringers to support the treads. A floating staircase uses a central or side-mount steel mono-stringer hidden inside the wall, so the treads appear to cantilever out from the wall with no visible support structure. Open riser staircases are significantly less expensive ($9,000 to $16,000 for 12 steps) than floating staircases ($15,000 to $40,000) because they eliminate the custom steel stringer fabrication.
