Custom kitchen cabinets really earn their keep during a remodel, especially when your space has odd angles, sloped ceilings, or dimensions stock cabinets won't cooperate with. New construction is another, since you can plan storage perfectly from the start. A lot of homeowners also reach out for built-in cabinets or custom bathroom cabinets when they want a look that matches the rest of the house. If you've measured a wall and nothing standard fits, that's the moment to go custom.
