12", 15", 18" & 21" Single Door Single Drawer - Special Order White Oak Inset Shaker Base Cabinet

Product details & specifications

This White Oak Inset Shaker Base Cabinet brings true inset construction to your kitchen in genuine solid white oak — 9–21" wide, with a single door and concealed soft-close hinges.

Real solid white oak, built to order

You can customize the width to the closest 1/4″. Click on the next larger size and reduce to your size. The door sits flush inside a solid oak face frame for the tailored, built-in-furniture look inset is known for, finished with a baked-on factory UV clear finish that lets the oak grain show through your stain. It’s stained, not painted — choose from six oak stains.

White oak brings a warm, straight, open grain that works in modern, transitional, and classic kitchens alike — a timeless finish that won’t date. Every white oak inset base cabinet is real solid oak under a baked-on factory UV clear finish over the stain you choose, so what you see is the true wood.

White Oak Inset Base Cabinet — FAQ

Is this real solid oak? Yes. The face frame and door are 100% solid white oak hardwood with a 5/8″ premium plywood box, finished with a baked-on factory UV clear finish.

Is it available in a color? Yes — choose from six oak stains: Saddle, Walnut, Coffee, Chocolate, Sand and Natural. It isn’t painted; the stain goes on the solid oak and is sealed with a baked-on factory UV clear finish, so the grain still shows. For painted cabinets in any Sherwin-Williams color, see our Custom Inset (painted) collection.

What is inset construction? The door and drawer fronts sit flush inside the face frame for crisp, even reveals and a custom-furniture look overlay cabinets can’t match.

Can I order a custom size? Yes. Pick a standard size or order the nearest larger stock size and specify your exact height, width, and depth.

How long does production take? Custom-order cabinets require 8–11 weeks for production.
