20-inch Deep Wood Stair Treads

Our 20-inch wood stair treads are an extra-deep, solid wood solution for staircases with larger-than-standard dimensions or custom design requirements. With an expansive 20″ depth, these treads accommodate unique architectural plans that call for an extended run on each step. Each tread is graded to be clear and usable on its top face, ensuring a defect-free surface for a professional finish. The underside may contain natural wood characteristics that do not impact the tread’s structural integrity. Treads are supplied unfinished and sanded, ready for a custom stain and seal.

These extra-deep treads are constructed from high-quality solid wood to provide a stable, durable surface for any high-traffic staircase. They are delivered unfinished and sanded, ready to be cut to size and finished on-site to perfectly integrate with your flooring and other stair parts. We stock these 20-inch deep treads in a variety of wood species and lengths to support the needs of custom builders. By offering this specialty size as a stock item, we help you avoid the significant lead times and expense of a custom mill order, ensuring you can get the material you need quickly.
