All engineering calculations, structural estimates, and electrical sizing metrics are provided for preliminary estimation only. Always ensure compliance with relevant statutory building codes and occupational safety standards, verified by a certified professional engineer before practical implementation.

Calculation Methodology

Total Area = Length * Width. Tile Count = (Area / Tile Area) * (1 + Waste%). Adhesive = Area * 4.5 kg/m². Grout = Joint Volume Formula.
