📐 Tile, Box, and Grout Calculator

⚠️ **Important Note:** The quantity of individual pieces is rounded **up** to the nearest full box. It's recommended to add an extra 5% / 10% to ensure the design pattern and avoid shortages due to breakages and cuts.
The grout calculation is a **theoretical estimate** and includes a **15% loss factor**. The actual material requirement may vary based on site conditions.
