Mitered cabinet doors are a type of cabinet door where the corners are cut at a 45-degree angle, creating a pictureframe joint where two pieces of wood meet. This creates a frame with a diagonal edge at each corner, giving the door a sleek and polished appearance. Mitered doors are often used in more traditional or upscale kitchen designs, adding a touch of sophistication to the cabinetry. They can be made from various types of wood and finished with different stains or paints to match the overall style of the kitchen.
