bullnose

Bullnose refers to a rounded edge or corner profile used in architecture, construction, and related trades. The term, derived from the rounded shape of a bull’s nose, denotes a design choice that softens sharp edges, reduces the risk of injury or chipping, and provides a finished aesthetic on edges that are frequently touched or exposed.

In tiling, bullnose tiles have a curved or rounded edge along one or more sides. They are used to finish the exposed edges of a tiled surface, such as bathroom walls, shower surrounds, and countertops. Bullnose tiles come in various radii and are selected to match the thickness of adjacent tiles, offering a smooth transition and a polished border without sharp cut edges.

Bullnose can also describe rounded brick profiles and mouldings. Bullnose bricks have one or more rounded faces and are used for decorative corners, edging, or planters, while bullnose mouldings are curved trim pieces made of wood, plaster, or stone used on door surrounds, baseboards, cornices, or window casings. In stair construction, bullnose stair nosings provide a rounded front edge to improve safety and aesthetics.

Manufacture and installation considerations include selecting the correct radius to match surrounding profiles, ensuring compatibility with substrate and tile thickness, and using appropriate adhesives and grout or mortar. Availability varies by material and supplier, and bullnose edges may influence cost and cutting requirements.

Overall, bullnose edges are a common finishing detail in both interior and exterior work, valued for safety, durability, and a soft, contemporary appearance. Related terms include bullnose tile, bullnose brick, and bullnose moulding.
