Unfinished products are considered commodities and will require some degree of additional minor prep-work before they can be considered complete, or "finished". Some degree of sanding / puttying is to be expected before finishing. Alternatively, consider ordering prefinished products.

Build your staircase with the wood species that defines contemporary American interiors. This unfinished White Oak traditional stair tread is the premium choice for new staircase construction and full tread replacement — 1 inch thick, 42 inches wide, ready for your stain or natural finish.

White Oak has become the dominant hardwood flooring choice in new US construction since 2018. Its tighter, straighter grain takes grey, greige, hardwax oil, and natural finishes without blotching — producing the clean, sophisticated look that defines modern and transitional home design. If you are building a staircase to match new White Oak floors, this is the only correct tread choice.

STAIN / FINISH TIP

White Oak's tighter grain produces exceptionally clean results with grey, greige, natural, and hardwax oil finishes — colors that blotch on Red Oak. For a precise floor match, test your stain on a cut-end scrap before finishing the full staircase.

Product Questions and Answers
  1. Q:What is a traditional 1-inch stair tread and when should I use it?
    A:A traditional stair tread is 1" thick — the standard for new staircase construction or full replacements where existing treads are removed. Required by most US building codes for new builds. Use when existing treads are too damaged to install over, or when building a staircase from scratch.
  2. Q:Why is White Oak the premium choice for modern staircase designs?
    A:White Oak has become the dominant hardwood flooring choice in new construction since 2018, driven by the popularity of wire-brushed and greige finishes. WoodStairCo unfinished White Oak treads are milled from the same species as premium flooring, making stain matching precise and predictable.
  3. Q:Can I stain this tread any color I want?
    A:Yes. Unfinished hardwood treads accept any oil-based or water-based stain. Sand lightly with 120-grit, apply chosen stain, allow to dry, then apply 2–3 coats of polyurethane. For floor matching: bring a floor sample to a paint store to identify the correct stain. We also offer a Red Oak Stain Colors Sample Pack for testing before committing to full treads.
  4. Q:What does closed or box end mean on a stair tread?
    A:Closed (box) end means both sides of the tread are cut square with no decorative return nosing — it fits wall to wall with both ends hidden. The correct style when neither end of your staircase is open to the room. Most widely available in all species, sizes, and finishes
  5. Q:Is 42 inches the most common residential stair width?
    A:42" is the most frequently ordered tread size in the US — typical for single-family homes built between the 1970s and 1990s. If you live in a standard residential home and are unsure of your stair width, 42" is a reasonable starting assumption. Always measure — but if your measurement falls between 40"–44", a 42" tread with minor trimming is usually the cleanest solution.
  6. Q:How are traditional stair treads installed?
    A:Traditional installation requires removing the existing tread first: pry from below or cut the nosing and pull off stringers. Once removed, check stringer surface is flat and clean. New treads are installed with construction adhesive plus screws from below, or toe-nailed through the back edge. Return styles need additional care when fitting around baluster holes or open stringer ends. Carpentry-level project — many homeowners hire a stair carpenter for best results.
