Red Oak Smoke Retro Stair Tread Closed 11.5 in wide x 36 in long - shipped pre-stained in Smoke and then finished with our UV Cured Diamond Coat II - ready to be cut-to-size and installed as soon as you receive them.

The most popular grey stain in the WoodStairCo lineup- Smoke bridges the gap between traditional warm Oak tones and modern cool-grey aesthetics. Install this 36-inch prefinished Red Oak retro tread over your existing steps in 30–45 minutes without touching a single existing tread.

Smoke is a grey-brown tone- warmer than a true grey, cooler than Gunstock- that pairs with grey-painted walls, white trim, and the farmhouse/transitional interior styles that have dominated US home design for the past decade. If your floors are grey, greige, or light brown, Smoke is your match.

Product Questions and Answers
  1. 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

  2. Q:Why is Red Oak the most popular species for stair treads?
    A:Red Oak accounts for over 50% of hardwood floors in US homes built before 2015, making it the natural match for most staircase upgrades. Janka hardness 1290 — handles residential traffic for decades. Open grain accepts stain evenly for consistent color matching to existing floors.

  3. Q:What is a retro stair tread and how does it differ from a traditional tread?
    A:A retro (retrofit) stair tread is 3/4" thick and installs directly OVER your existing tread — no removal required. The flat bottom sits flush over the current step. Traditional treads are 1" thick and used in new construction or full replacements where existing treads are removed. If your staircase structure is sound, retro treads are faster, less invasive, and DIY-friendly.

  4. Q:What is the step-by-step process for installing a retro stair tread?
    A:Step 1: Measure existing tread width and trim retro tread to fit (1/16" gap each end). Step 2: Clean existing tread surface — remove staples, wax, debris. Step 3: Apply Loctite PL Premium adhesive in S-curves across entire back of tread. Step 4: Press firmly onto existing tread and nail with brad nailer at 6" intervals along front nosing and back edge. Step 5: Wipe excess adhesive. Allow 24 hours before walking on. Time per tread: 30–45 minutes.

  5. Q:What does the Smoke stain finish look like?
    A:Smoke is a grey-brown stain — cool and muted but not fully grey. It bridges warm traditional and modern grey-palette homes. Works well with grey-painted walls, white trim, and contemporary furniture. On risers, Smoke pairs naturally with white painted risers for a two-tone modern staircase look.

  6. Q:Is 36 inches a standard stair tread width?
    A:36" is the standard minimum width for townhomes, condos, basement staircases, and older homes. Most US residential building codes require a minimum 36" clear stair width. If measuring a tight staircase — townhouse, older colonial, or basement — 36" treads will typically fit. Always measure wall to wall before ordering.
