The most expensive type of kitchen cabinets are custom-made, handcrafted models. They allow for a wide range of customization options and can be made from the highest quality materials available. Generally speaking, these cabinets will cost several thousand dollars or even more depending on the size, material selection, labor involved in their construction and any other customizations that you may request. The costliest of all kitchen cabinet types would likely be those constructed using exotic hardwoods such as ebony or rosewood. These types of woods are inherently dense and heavy, while also being extremely beautiful when they have been finished with a lustrous coat of lacquer. Additionally, some finely hand-carved cabinetry might feature intricate designs which add to their hefty price tag. Other luxurious choices include semi-custom European style integrated cabinetry that is usually fitted with top-of-the-line accessories such as pullout drawers for easy access to frequently used items as well as millwork finishes like crown moulding and wainscotting throughout your kitchen space. No matter what type of kitchen cabinets you choose for your home renovation project, it is important to remember that quality materials combined with proper craftsmanship will always result in timeless features that can last generations if properly cared for. Keep this in mind when deciding how much you are willing to spend on this important investment in order to ensure lasting value no matter where life takes you!
