Doorway Arch Kits

Turn square corners into a softer view.

Choose subtle rounded corners or a full half-circle arch. Our made-to-order forms create the shape; you blend and paint them into your wall.

Arch forms only. Installation and finishing are required.

Two shapes. One simple upgrade.

Choose your curve.

Both kits include a matched pair of forms, sized to your wall thickness.

Before you choose

Soft Corner needs your wall thickness. Full Span also needs the exact width across the top of the opening.

Enter your measurements on the product page. The order card calculates the size and finishing allowance.

Dry-fit, attach, tape and blend the seams. Prime and paint to match the wall. These are forms, not a pre-finished doorway.

Doorway kits are different from inserts for BILLY shelves or KALLAX cubes.
