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 in a clear UV lacquer that lets the natural oak grain show. This is a natural-wood cabinet, not painted.

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 sink base cabinet is real solid oak with a clear UV lacquer top coat, so what you see is the true wood.
