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.

The most affordable left return option in the WoodStairCo range — and the most flexible. At $46.80, this unfinished Red Oak traditional left return stair tread finishes the open left end of your 42-inch staircase and accepts any stain color you choose — the exact stain on your existing floors included.

The lowest price entry point for an open-sided traditional staircase. Right for budget-conscious full staircase renovations, rental properties, and new construction projects where on-site staining is already in the plan.
