We build both semi-custom and full custom cabinetry, and a common early question is which one you actually need. The right choice depends on your space, your budget, and how much of your kitchen needs to be one of a kind.
The Three Tiers of Cabinetry
- Stock cabinets are mass-produced in fixed sizes and finishes, usually off the shelf at big-box stores. They're the least expensive but have the fewest options.
- Semi-custom cabinets start from standardized box sizes, then let you choose door styles, finishes, and modifications like adjusted depths, accessories, and interior options.
- Full custom cabinets are built to order to any dimension, configuration, or design you need.
Side-by-Side Comparison
| Semi-Custom | Full Custom | |
|---|---|---|
| Sizing | Standard widths, with filler strips to close gaps | Built to exact dimensions, wall to wall and floor to ceiling |
| Design flexibility | Wide choice of doors, finishes, and accessories | Unlimited: unique profiles, angles, and furniture-style details |
| Fit in older homes | Works well with careful scribing and fillers | Ideal for out-of-square walls and unusual spaces |
| Cost | More budget-friendly | Higher investment |
| Lead time | Generally shorter | Generally longer |
Choose Semi-Custom If…
- Your kitchen has a fairly standard layout and straight walls.
- You want a high-end look with a more predictable budget.
- You're working toward a specific timeline.
- Your style choices are covered by the available door styles and finishes. We offer 50+ door styles.
Choose Full Custom If…
- You have angled walls, sloped ceilings, or tight, awkward spaces.
- You want cabinets to fit exactly with no visible fillers.
- You're designing furniture-style pieces like a statement island, a hutch, or a range hood surround.
- You need built-ins outside the kitchen, such as bookcases and entertainment walls, home office cabinetry, or closet systems sized to the room.
The Best of Both: Mixing Semi-Custom and Custom
Many kitchens combine the two. Semi-custom boxes handle the perimeter runs, and full custom pieces go where they make the biggest impact, like the island, a pantry wall, or a tricky corner. You get a one-of-a-kind look where it shows without paying custom prices for every box. Read more about pricing in our kitchen cabinet cost guide.
Questions to Ask Any Cabinet Company
- Are these semi-custom or full custom? What can and can't be modified?
- What are the boxes made of?
- Where are the cabinets made? (Ours are American-made.)
- Who installs them: your own crew or a subcontractor?
- Will I see a design before I commit? (Every Si Belle project includes a 3D design preview.)
Frequently Asked Questions
Are semi-custom cabinets good quality?
Yes. Semi-custom refers to how cabinets are sized and configured, not their quality. Well-built semi-custom cabinets with quality boxes, hardware, and finishes can last for decades.
How long do custom cabinets take compared to semi-custom?
Full custom cabinets generally take longer because each piece is built to order. Most of our kitchen projects take 6–10 weeks from final design approval to installation, and we give you an exact timeline at your consultation.
Can I mix semi-custom and full custom cabinets in one kitchen?
Absolutely. Using semi-custom boxes for the perimeter and full custom pieces for the island or feature walls is one of the smartest ways to balance budget and design.
