Understanding Tile Installation
Tile Types & Applications
Ceramic Tiles
Most common and affordable. Good for walls and light-traffic floors. Easy to cut and install.
Porcelain Tiles
Denser and more durable than ceramic. Excellent for high-traffic areas and outdoor use.
Natural Stone
Marble, granite, travertine. Unique patterns but requires sealing and special care.
Glass Tiles
Popular for backsplashes and accent walls. Reflects light and creates visual interest.
Planning Considerations
Layout Planning
Start from the center of the room and work outward. This ensures balanced cuts at edges.
Waste Factor
Add 10-15% extra tiles for cuts, breakage, and future repairs. Complex layouts need more.
Grout Lines
Wider grout lines are more forgiving but collect more dirt. Consider maintenance needs.
Installation Materials
Tile Adhesive
Use appropriate adhesive for tile type and substrate. Coverage: ~3-4 kg per square meter.
Grout
Sanded for wide joints (>3mm), unsanded for narrow. Coverage depends on tile size and grout width.
Spacers
Ensure consistent grout lines. Use 4 spacers per tile for best results.
Edge Trim
Provides finished edges and protects tile edges from damage.

Frequently Asked Questions
How accurate are these tile calculations?
Our calculations are very accurate for rectangular rooms and standard tile layouts. Complex patterns or irregular shapes may require professional measurement.
What waste factor should I use?
Use 10% for simple layouts, 15% for diagonal or complex patterns, and 20% for intricate designs or if you're inexperienced with tile installation.
How do I calculate grout coverage?
Grout coverage depends on tile size, grout line width, and tile thickness. Our calculator uses standard formulas based on these dimensions.
Should I buy extra tiles?
Yes, always buy 5-10% extra tiles beyond the waste factor for future repairs. Tile lots can vary in color and may be discontinued.
