21-Inch Lite Gray Shaker Base Cabinet
The GB21 is a 21-inch-wide Lite Gray Shaker Base Cabinet featuring one drawer, one door, and one adjustable shelf. It offers additional storage over an 18-inch cabinet while maintaining the versatility of a single-door design. If your layout has room for a GB21, the extra width gives you greater flexibility for organizing everything from cookware to household supplies.
Like the GB18, the GB21 is a popular choice beside a sink for homeowners planning a trash pullout. The additional cabinet width can accommodate larger aftermarket pullout systems, making it an excellent option when a standard double 28-quart system isn't large enough.
Why Choose a GB21 Base Cabinet?
The biggest advantage of the GB21 is simple—it provides more storage. If your kitchen layout allows for the additional width, you'll gain more usable cabinet space while keeping the convenience of a single drawer and single-door configuration.
The GB21 is also an excellent choice for homeowners planning a larger trash pullout than a
GB18 Base Cabinet
can typically accommodate. As always, verify the manufacturer's cabinet opening requirements before purchasing any aftermarket pullout system.
Common Uses for a GB21
- Larger aftermarket trash pullout systems
- Cleaning supplies
- Trash bags and recycling supplies
- Small kitchen appliances
- General kitchen storage
- Additional storage wherever a 21-inch cabinet fits the layout
GB21 vs. GB18
The
GB18 Base Cabinet
is our standard recommendation for a double 28-quart trash pullout and works well in many kitchens.
Choose the GB21 when you have additional room available and want more storage or plan to install a larger compatible trash pullout system. The decision usually comes down to available space and your storage needs.
GB21 vs. GB24
If your layout has room for a
GB24 Base Cabinet
and you are not planning to install a trash pullout, we generally recommend the larger cabinet. More cabinet space provides greater storage flexibility, and homeowners rarely regret having additional storage.
The GB21 remains the better choice when your available space is limited to approximately 21 inches or when your planned trash pullout system is designed for this cabinet size.
Designed for Everyday Kitchens
The Partial Overlay Shaker design complements traditional, Craftsman, farmhouse, and transitional kitchens while maintaining the timeless appearance of framed cabinetry. The exposed solid poplar face frame provides a comfortable grip for opening doors and drawers, allowing decorative hardware to be added whenever you choose—but never requiring it.
Whether you prefer cabinet knobs, pulls, or no hardware at all, the Partial Overlay design offers the flexibility to match your style while remaining practical for everyday use.
Built to Last
Built in America, the GB21 features a solid poplar face frame, solid poplar Shaker door and drawer front with recessed birch plywood center panels, and a durable birch plywood cabinet box. We build our cabinets using hardwood and furniture-grade plywood—never MDF, particleboard, or engineered wood products—for long-term strength, durability, and dependable everyday performance.
Soft-close concealed hinges and full-extension soft-close drawer glides provide smooth, quiet operation. The cabinet is factory finished with Sherwin-Williams Lite Gray and arrives ready for installation.
Before You Order
Before ordering, verify your cabinet layout, appliance clearances, and any required fillers. If your kitchen can accommodate a wider cabinet without affecting the overall design, moving up in size usually provides better long-term storage and organization.

Professional Recommendation
The GB21 is an excellent choice when you want more storage than a GB18 provides while keeping the flexibility of a single-door design. It's particularly well suited for homeowners planning a larger trash pullout beside the sink or anyone who simply has room for additional storage.
If your layout can accommodate an even wider cabinet and a trash pullout is not your priority, we generally recommend moving up to a
GB24 Base Cabinet.
As we often tell customers, if you have the room, bigger is usually better.
