Combining stock and custom cabinets can be a smart strategy for balancing cost with customization. Use stock cabinets for standard areas of the kitchen where conventional sizes and styles work well. Custom cabinets can then be employed for specific areas needing tailored solutions, like corner units. This approach allows for personalization where it's most impactful while keeping kitchen remodel costs down. However, you should ensure your kitchen design remains cohesive by matching colors and finishes across both types of cabinetry.
