Why Tile Cutting Needs Optimization
Tile installation is one of the most wasteful construction activities when done without planning. A typical bathroom tiling project wastes 12-20% of tiles on cuts that do not fit. For a 20m² bathroom using $40/m² porcelain tiles, that is $96-160 wasted.
Tile cutting optimization solves this by computing the exact layout of tiles on each surface. The optimizer determines how many full tiles are needed, where cuts should be made, and how to arrange the layout to minimize waste. It accounts for grout lines, room dimensions, and any obstructions.
For professional tile contractors doing 2-3 installations per week, optimization can save $200-500 per month on material costs. It also reduces cutting time by eliminating the "measure twice, cut once" guesswork.
Tile Cutting Best Practices
Measure Room Accurately
Measure the room length, width, and any obstructions (pillars, alcoves) to the nearest millimeter. The more accurate your measurements, the better the tile layout.
Account for Grout Lines
Add grout line width (typically 2-5mm) to each tile dimension before entering into the optimizer. This ensures the cut tiles fit correctly with proper spacing.
Order 10% Extra Tiles
Always order 10-15% more tiles than calculated. This covers breakage during cutting, installation mistakes, and future repairs. The optimizer tells you the minimum — add a buffer.
Plan Cut Tiles at Edges
Cut tiles should be placed along walls, not in the center of the room. Enter your room dimensions and full tiles to get a layout that minimizes cuts and places them at edges.
