Extending kitchen wall cabinets to the ceiling
I would take an inventory of exactly what you have and see if you can find a manufacturer who can get you what you need. Alternately, you may replace the units that are hard to find with taller cabinets.
Instead of matching I would advise selecting a finish that compliments what you have. It is very much “on trend” to mix finishes and even wood types in a kitchen these days.
