What is the difference between stock semi-custom and custom cabinets?

Stock cabinets are pre-built in standard sizes and ship immediately, semi-custom cabinets offer more size and finish options with a 4-8 week lead time, and custom cabinets are built to your exact specifications by a local shop over 8-16 weeks. The differences come down to sizing flexibility, material quality, finish options, and — most significantly — price.

Stock cabinets ($5,000-$10,000 for a typical NB kitchen) are mass-produced in standard widths — usually 9, 12, 15, 18, 21, 24, 30, 33, and 36 inches. They come in a limited selection of door styles and finishes, typically available off the shelf or within 1-2 weeks. The advantage is speed and cost. The limitation is that your kitchen dimensions may not divide evenly into standard sizes, requiring filler strips at the ends that can look awkward if not handled carefully. Stock cabinets are available at big box stores across NB and are a solid choice for straightforward galley or L-shaped layouts where standard sizes fit well. Box construction is typically particleboard with melamine coating — functional but less durable than plywood, particularly around sinks in NB's humid climate.

Semi-custom cabinets ($10,000-$18,000) are where most NB kitchen renovations land. Semi-custom lines are built to order from a manufacturer's catalogue, offering dozens of door styles, wood species, paint colours, and stain options. The critical advantage over stock is sizing flexibility — semi-custom cabinets can be ordered in 1/8-inch increments in width, with varying heights and depths, meaning your kitchen can be fitted precisely without filler strips. You also get better construction: plywood boxes are commonly available, soft-close hardware is usually standard, and drawer boxes are solid wood or plywood rather than stapled particleboard. Lead time is 4-8 weeks from order to delivery, so plan accordingly — in NB, ordering by March or April ensures a summer installation.

Custom cabinets ($18,000-$25,000+) are built from scratch by a local cabinet shop to your exact specifications. There are no catalogues or standard options — every dimension, material, finish, joint, and detail is decided by you and the builder. Custom is the right choice when your kitchen has unusual dimensions (old Fredericton or Saint John homes with non-square walls, varying ceiling heights, or odd alcoves), when you want a specific wood species or finish that semi-custom lines do not offer, or when you need specialized storage solutions built in. Custom cabinet makers in NB typically have 8-16 week lead times, and many are booked months in advance during the busy May-October renovation season.

How to Decide

The decision often comes down to your kitchen's layout complexity and your budget. If your kitchen has standard dimensions and you are doing a straightforward replacement on a budget, stock cabinets with plywood box upgrades deliver good value. If you want a tailored fit with quality materials and have a mid-range budget, semi-custom hits the sweet spot — this is the most popular choice for NB kitchen renovations. If you have an older home with non-standard dimensions, want a truly unique kitchen, or are investing in a high-end remodel ($50,000+), custom cabinets are worth every dollar.

One important consideration for NB specifically: material selection matters more than cabinet tier in our climate. A semi-custom cabinet with MDF-core painted doors and plywood boxes will outperform a custom cabinet with thermofoil doors and particleboard boxes in NB's humidity swings. Focus on the right materials first, then choose the tier that fits your budget and layout needs.

Getting quotes at all three levels lets you see the actual price differences for your specific kitchen. New Brunswick Kitchens can match you with renovators who carry multiple cabinet lines to compare options side by side.
