How to Extend Kitchen Cabinets to Ceiling

Extending cabinets to the ceiling not only adds a sense of luxury to your kitchen space but also enhances storage capability. This approach completely impacts the appearance of your kitchen, giving it a smooth and polished appearance. Whether you want a more modern look or just extra storage space, extending your kitchen cabinets to the ceiling is a practical and visually pleasing option. 

You’ll learn the process step by step here on how to extend kitchen cabinets to ceiling, giving helpful suggestions and insights to help you achieve a professional and unique design for your kitchen.

1. Build additional boxes to extend kitchen cabinets to ceiling

Begin the process of extending your kitchen cabinets to the ceiling by constructing more boxes that will fit in with the existing cabinetry. Measure the distance between the top of your existing cabinets and the ceiling with perfection for an ideal fit. Make the new boxes out of plywood or medium-density fiberboard (MDF), and cut the pieces to fit your sizes.

Use wood glue and screws to assemble the boxes, strengthening the connections for longevity. To maintain a consistent look, the materials and concludes of the existing cabinets must be matched. Once the boxes are completed, place them atop the existing cabinets, ensuring that they exactly line, and strongly attach them. This preliminary phase lays the groundwork for the rest of the project, giving a strong structure for the enlarged cabinets.

2. Putting in the new upper cabinets

After laying the foundation, the next important step in extending your kitchen cabinets to the ceiling is to install the additional upper cabinets. Begin by firmly connecting the expanded boxes to the existing cabinets with screws pushed through the back panel of the boxes into the wall studs. For a professional completion, make sure the boxes are level and plumb.

Use wood filler to cover any gaps or seams between the new and old cabinets. Once the expanded boxes are securely in place, connect the cabinet doors, handles, or knobs, keeping the current design in mind. This exacting installation technique guarantees that the expanded cabinets not only increase storage space in your kitchen but also blend smoothly with the current design for a polished and solid effect.

3. Provide the new upper cabinet with a personalized look

Creating unique items from your expanded upper cabinets provides a customized touch and enriches the overall beauty of your kitchen. Begin by crown molding the top and sides of the cabinets to give a stylish, complete look. For an overall design, use molding that compliments the style of your existing cabinets. Sand the surfaces to give a smooth finish after filling any gaps or seams with wood filler.

Consider adding decorative trim or beading to the cabinet doors to further personalize them. Painting or staining the expanded cabinets in a color that complements the existing cabinetry improves the overall look. This attention to detail not only adds character to your kitchen but also guarantees that the enlarged cabinets fit in with the original design, resulting in a unified and individualized look.

After the building process is completed, you must execute the following:

Following the completion of the expanded cabinet construction and installation, various activities must be completed to ensure a polished and functioning outcome:

  • Fill Gaps and Seams: Fill any gaps or seams between the new top cabinets and the existing ones with wood filler. This process gives a professional and flawless appearance.
  • Sand Surfaces: Sand the cabinets to smooth down any rough edges or surfaces. This technique prepares the cabinets for painting or staining and gives them a polished appearance.
  • Prime and Paint or Stain: To prepare the surface for painting or staining, use a primer on the cabinets. For an overall effect, choose a color that enhances the existing cabinets. A smooth and even finish may need several coats.
  • Install Cabinet Hardware: Attach handles, knobs, or pulls to the cabinet doors to match the existing hardware. This phase gives a final touch and ensures that the design is consistent throughout the kitchen.
  • Apply a Protective Finish: Consider putting a clear protective coating on the cabinets, such as polyurethane. This protects the wood and finish from wear and tear, extending the life of your newly enlarged cabinets.
  • Clean and Organize: Clean both the new and existing cabinetry once they have been thoroughly completed and dried. Organize the interior of the extra cabinets to properly maximize storage space.
  • Admire Your Work: Take a moment to reflect on the progress you’ve made. The enlarged cabinets not only increase storage but also contribute to a more aesthetically pleasing and consistent look in your kitchen.


The kitchen cabinet extension to the ceiling is an innovative project that improves both usefulness and attractiveness. You’ve not only increased storage but also created an effectively connected and individualized area by carefully designing, installing, and modifying. The attention to detail results in a kitchen that is spacious harmonious, and personalized to your taste.
