Add a tile quantity calculator to product pages so customers can estimate how many whole boxes to buy. Configure tile dimensions, pieces per box, published carton coverage, waste allowance, units, and storefront labels from Shopify admin. The calculator uses product-specific values and rounds purchase quantities to complete boxes.

• Estimate whole tile boxes from shopper-entered room/area dimensions
• Use rectangular tile dimensions and published carton coverage
• Apply configurable waste allowances and measurement units
• Reuse presets and override values for selected products
• Show optional calculation details with merchant-controlled lables
