Bathroom Tile Edge Cut Layout Planner
Explore equal cut widths on both ends of one straight tile row. Enter actual tile dimensions, an approved grout joint, the perimeter clearance and your own minimum cut limit; then dry-lay before installing.
Choosing tile is different from laying it out
Our Bathroom Tile Materials Guide compares porcelain, nonporcelain ceramic and natural stone for bathroom use, including product suitability, maintenance, safety and wet-area assemblies. The existing Tile Calculator estimates whole project tile quantity and boxes. This planner solves a separate issue: where the first and last cut pieces land in one uninterrupted row, not how many boxes to buy.
The Tile Council of North America explains that tile layout, correct joints and compatible wet-area systems require separate verification. Grout joints are not waterproof; shower construction requires an appropriate complete system. A symmetrical cut is not evidence of a properly waterproofed shower.
Measure the tile face before trusting the edge cuts
A tile sold under a nominal 12-inch description may not have an actual 12-inch face. A small difference repeated across a row can change both border cuts. Measure several tiles from the actual batch and distinguish the field grout joints between tiles from the movement gaps at the boundaries.
The layout balances one straight span. It cannot decide waterproofing, substrate preparation, movement-joint placement or the full two-dimensional layout around a drain, niche or doorway. A minimum-cut input expresses your chosen planning constraint; it is not a universal installation specification.
Check before the next step
Dry-lay a representative row with the intended spacers, check the measured span at several points and follow the tile-system requirements before fixing a starting line.
