How many tiles do I need for a 12×12 room?
144 sq ft + 10% waste = 159 sq ft. For 12×12 inch tiles, that's about 159 tiles (11 boxes of 15). Always round up when ordering to account for cuts and breakage during installation.
Should I choose porcelain or ceramic tile?
Porcelain is denser and more water resistant (absorption rate <0.5%), ideal for bathrooms, kitchens, and outdoor use. Ceramic tiles are more affordable and easier to cut, great for walls and dry areas. Both come in countless designs.
How wide should grout lines be?
Standard: 1/8" for most floor tiles. Rectified (precision-cut) tiles can use 1/16". Larger tiles (18"+) often use 1/8" to 3/16". Wider grout lines are more forgiving for uneven surfaces.
How do I calculate tile for a bathroom with odd shapes?
Split the floor into rectangles. Measure each section separately. Add sections together plus 15–20% waste for the extra cuts around fixtures, tub, and toilet.
What's the best tile for kitchen floors?
Porcelain tile is the top choice for kitchens: it's water-resistant, scratch-resistant, and easy to clean. Choose textured or matte finishes with a slip rating for safety. 12×24 or 18×18 sizes are popular for kitchens.
