Frequently Asked Questions
Calculate the area by multiplying length by width. Determine the area of one tile and divide the total area by the tile area. Add 10% waste for standard installations or 15-20% for diagonal and herringbone patterns. Our calculator does all of this automatically.
Grout needed depends on tile size and grout width. For 12x12 tiles with 1/4 inch grout lines, you need approximately 1 pound of grout per 10 square feet. Larger tiles require less grout per square foot, while smaller tiles and wider grout lines require more.
Diagonal and herringbone patterns waste significantly more tile than straight layouts, typically 15-20% compared to 5-10% for straight installations. Herringbone patterns waste the most due to the angled cuts required at walls and corners.
Yes, it's recommended to buy 5-10% extra tiles beyond your calculated needs to keep for future repairs. Tiles can break during installation and matching the exact dye lot years later is often impossible. Store extra tiles in a dry location.
For small bathrooms, medium to large tiles (12x24 or 18x18 inches) can make the space feel larger with fewer grout lines. Small tiles (8x8 or smaller) work well for shower floors and accent walls but require more grout and installation time.
