The costliest element of a kitchen remodel is often the cabinetry. Custom or semi-custom cabinets, especially when made from high-quality materials, can significantly impact the overall budget. Additionally, if you opt for specialty features like built-in appliances, high-end countertops, or intricate tile work, these can also contribute to the overall expense. It's important to allocate a significant portion of your budget for cabinetry and prioritize accordingly.
