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.
