Our cabinet doors and drawer fronts are made using only the finest select grade woods. For oak cabinet doors or drawer fronts, we use Northern Red Oak, selected for color uniformity. For maple cabinet doors or drawer fronts, we use White Hard Maple, chosen for whiteness and uniformity of color. For cherry cabinet doors and drawer fronts, we use select grade Cherry with a 96% minimum of heartwood on the front side. (Please note that we give great effort towards matching the degree of heartwood on the front side of the unfinished cabinet doors and drawer fronts in your order). Paint-grade Maple and Birch cabinet doors and drawer fronts are not uniform in color and are intended to be painted. Flat-panel doors use quarter-inch Maple, Oak, or Cherry plywood panels. Please note that veneers may accept stain differently than the solid wood frames. For a complete listing of door styles available for our custom cabinet doors, please see our product catalog.
