The most expensive cabinets in the United States are typically custom-made cabinets. These cabinets are priced higher due to their unique designs, high-quality materials, and the craftsmanship involved in their creation. According to the National Kitchen & Bath Association (NKBA), custom cabinets can range from $100 to $1,000 per linear foot, depending on the materials, design complexity, and the level of customization. In contrast, semi-custom cabinets, which offer more limited design options, can cost between $75 to $500 per linear foot. Stock cabinets, the most affordable option, are generally priced between $50 to $300 per linear foot. The significant price difference between custom and stock cabinets is primarily due to the labor-intensive process of crafting custom pieces, which includes hand-cutting, sanding, and finishing. Additionally, custom cabinets often use premium materials such as solid wood, which adds to their cost.
