Calculate bullnose edge tiles needed for finished tile edges. Enter the total linear feet of exposed edges and tile size for an accurate piece count.
Bullnose tiles are specially shaped pieces with one or two finished (rounded or beveled) edges. They're used to create a clean, polished termination where tile meets an untiled surface — such as the top of a backsplash, the edge of a half-tiled wall, or around a window frame in a shower.
This bullnose tile calculator helps you determine how many bullnose pieces you need based on the total linear feet of exposed tile edges and the size of each bullnose piece. Bullnose tiles typically match the field tile in width (e.g., a 12” bullnose for 12” field tile) and are sold by the piece.
Proper bullnose planning prevents unfinished or rough tile edges in your project. Some modern installations use Schluter metal edging strips instead of ceramic bullnose, but traditional bullnose remains the most popular finishing option.
Integrating this calculation into the estimating workflow reduces reliance on rules of thumb and improves the accuracy of material takeoffs and budget projections for every job.
Bullnose tiles cost $2–$10+ per piece, and a typical bathroom can have 30–50 LF of exposed edges. Under-ordering leaves raw tile edges visible. This calculator converts your edge measurements to an exact piece count. This quantitative approach replaces rule-of-thumb estimates with precise calculations, minimizing material waste and reducing the likelihood of costly change orders during construction.
Pieces = ⌈(Total LF × 12 / Bullnose Length) × (1 + Waste%/100)⌉
Result: 27 pieces
24 LF = 288 inches. At 12” per piece: 288 / 12 = 24 pieces. With 10% waste: ⌈24 × 1.10⌉ = 27 bullnose pieces.
Surface bullnose has one rounded edge matching the field tile width. Double bullnose has two adjacent finished edges for outside corners. Pencil liner is a narrow decorative strip. Quarter round is a convex trim piece for transitioning between planes.
Top edge of a kitchen backsplash. Sides of a shower niche. Upper edge of a half-height bathroom wall. Window sill in a shower. Around the perimeter of a tile panel or accent feature. Any termination where raw tile edge would be visible.
Schluter metal edge profiles (Jolly, Rondec, Quadec) are a popular modern alternative. They install under the last row of tile and create a clean metal edge. Available in chrome, brushed nickel, brass, and matte black finishes.
Bullnose is often sold individually (not by the box). Order bullnose at the same time as field tile to ensure lot matching. Some distributors have long lead times for bullnose — order early. Keep 2–3 extra bullnose pieces for future repairs.
Bullnose tile has one edge that is finished (rounded or beveled) instead of the raw, unglazed edge of standard field tile. It creates a clean termination where tile ends and meets a wall or other surface.
Anywhere an exposed tile edge is visible: top of a backsplash, edges of a half-tiled wall, around window/niche openings in showers, and where tile meets a different material like drywall. Comparing your results against established benchmarks provides valuable context for evaluating whether your figures fall within the expected range.
Use a metal edge trim (Schluter Jolly, Rondec, or similar). Some tilers polish the cut edge of porcelain tile for a clean look. You can also use stone-cut tile with a polished edge.
Bullnose pieces typically cost 1.5–3x more per piece than the equivalent field tile. A 12” bullnose piece runs $3–$10 depending on the tile line. Budget bullnose may not be available for all tile styles.
Surface bullnose matches the field tile width and has a rounded top edge. Pencil bullnose is a narrow (~3/4” × 12”) trim piece that creates a subtle edge detail. Pencil bullnose is more decorative but doesn't cover as much.
No. Caulk fills joints but doesn't finish the exposed tile edge. The raw edge of a cut tile is unglazed and porous. Bullnose or metal trim is needed for a proper finished edge.
