Wood Tread Options for Your Floating Staircase

At San Francisco Floating Stairs Specialists , wood tread selection is a structural and aesthetic decision made together with the client — not a catalog choice added at the end.

White oak is the most requested wood species for Bay Area floating stairs. It accepts a wide range of stains and oil finishes, holds up well under daily traffic, and its tight grain pattern ages cleanly without showing wear unevenly. Walnut offers a richer, darker tone with dramatic grain — a natural pairing with dark steel and frameless glass in modern Pacific Heights or Marin County interiors.

Ash provides a lighter, more open grain pattern at a more accessible price point. It machines cleanly and finishes consistently, making it a practical choice when the design calls for a bright, Scandinavian-influenced look. Teak is the densest option — an oily hardwood with natural resistance to moisture that performs well in coastal Bay Area conditions or indoor-outdoor installations near Marin or the Peninsula.

Every tread is acclimated to your home's actual indoor humidity and temperature conditions before installation. Skipping this step leads to movement, cracking, and finish separation. We build the acclimatization window into our project schedule as a non-negotiable step — not an optional add-on.

Tread thickness is determined by span, load, and species — not by default. We calculate structural thickness for each installation based on cantilever length and CBC load requirements, then match that specification to your selected wood species. Tread edges are either eased, chamfered, or finished square depending on the design intent.
