When planning a home renovation or building a new space, tiles are one of the most important design decisions you will make. They influence not only your home’s aesthetics but also its long-term durability and maintenance needs. However, many homeowners struggle to judge tile quality before purchasing. Poor-quality tiles may crack early, fade over time, or fail under heavy weight—leading to expensive repairs.
This detailed guide provides a Tile Quality Checklist for Homeowners, helping you choose durable, certified, and long-lasting tiles with confidence. From understanding tile strength to verifying certifications, you’ll learn exactly how to check tile quality before investing.
1. Check Tile Type: Porcelain vs Ceramic vs Others
Choosing the right tile type is the foundation of tile quality. Not all tiles are built the same, and different materials serve different purposes.
✔ Porcelain Tiles
Porcelain is considered one of the best tile types for homes.
- Dense and strong
- Low water absorption (<0.5%)
- Ideal for bathrooms, kitchens, outdoor areas
- Better suited for high traffic areas
✔ Ceramic Tiles
Ceramic is more budget-friendly and works well for indoor areas.
- Easier to cut and install
- Slightly less durable than porcelain
- Suitable for bedrooms, living rooms, feature walls
✔ Vitrified Tiles
An excellent option for long-lasting interiors.
- High tile strength
- Stain-resistant
- Ideal for both indoor and outdoor use
✔ Natural Stone (Marble, Granite)
Visually premium but requires more maintenance.
Tip: When comparing porcelain vs ceramic, choose porcelain for durability and ceramic for affordability.
2. Perform a Tile Durability Test
Before buying, conduct quick tests—or ask the supplier for test reports—to determine the tile’s durability.
✔ Scratch Test
Use a coin or key to lightly scratch the surface.
High-quality tiles show no visible marks.
✔ Water Absorption Test
Low absorption = high strength.
- Porcelain absorbs < 0.5%
- Ceramic absorbs 3–7%
Ask the seller for the tile’s water absorption rate.
✔ Load/Weight Test
Quality tiles withstand heavy pressure.
A tile that cracks easily in hand is not durable.
✔ Sound Test
Tap the tile gently.
A clear, ringing sound means proper density;
a dull sound may indicate internal cracks or poor baking.
3. Check Tile Thickness (Tile Thickness Guide)
Tile thickness directly affects durability and installation quality.
✔ Standard Tile Thickness
- Ceramic tiles: 6–10 mm
- Porcelain tiles: 8–12 mm
- Outdoor tiles: 12–20 mm
Thicker tiles offer better:
- Strength
- Load capacity
- Crack resistance
Avoid thin tiles for high-traffic areas such as hallways or kitchens.
4. Verify Tile Certifications
Authentic tiles come with industry-standard certifications that prove their quality.
✔ Important Certifications to Look For
- ISO 13006 (global quality standard for ceramic tiles)
- CE marking (European quality standard)
- EN 14411 (EU tile classification)
- BIS certification (for India/Pakistan region manufacturers)
These certifications ensure your tiles meet standards for:
- Strength
- Water absorption
- Surface quality
- Durability
Buying tiles with proper certifications guarantees you’re investing in quality and safety.
5. Inspect Tile Strength and Grade
Tiles are graded based on their durability levels. Make sure to choose the correct grade for your space.
✔ Tile Strength Grades
Grade 1: Decorative walls only
Grade 2: Light traffic rooms (bedrooms)
Grade 3: Medium traffic indoor areas
Grade 4: High traffic areas (kitchens, halls)
Grade 5: Commercial buildings and outdoor areas
Higher grade = better tile strength and wear resistance.
6. Examine Tile Finishing & Surface Quality
Tile finishing affects not only appearance but also maintenance and safety.
✔ Check for Surface Defects
Avoid tiles with:
- Chips
- Uneven edges
- Color patches
- Surface bumps
- Misaligned patterns
✔ Glossy Finish
- Suitable for walls and low-traffic floors
- Easy to clean
- Slippery when wet
✔ Matte Finish
- Slip-resistant
- Ideal for bathrooms and outdoor areas
- Hides dust and stains better
✔ Textured Finish
- For functionality (anti-slip)
- Great for poolside, patios, porches
Good tile finishing should feel smooth, consistent, and defect-free.
7. Check for Color and Shade Variation
High-quality tiles maintain consistent shades and tones.
✔ Tile Shade Number
Tiles of the same shade number match perfectly.
Always check the box for the same batch and shade code.
Variation in shade can ruin your floor’s uniform appearance.
8. Examine Tile Dimensions and Size Accuracy
Tile edges should be perfectly straight and equal in measurement.
✔ How to Check
- Keep two tiles together
- They should align without gaps
- Check diagonals for symmetry
Poor dimensional accuracy causes:
- Uneven grout lines
- Difficult installation
- Crooked tile layout
Choose rectified tiles for the most precise edges.
9. Slip Resistance Rating
For safety, especially in wet areas, check the slip resistance rating (R-value).
- R9–R10: Indoor use
- R11–R12: Wet areas (bathrooms, kitchens)
- R13: Outdoor, high-slip-risk areas
Higher R-value = more slip-resistant.
10. Ask the Right Questions Before Buying Tiles
When buying tiles for home, always ask the dealer these questions:
- What is the water absorption rate?
- Is the tile certified?
- What is the PEI rating (surface durability rating)?
- Is it suitable for high traffic areas?
- What’s the thickness of the tile?
- Are these tiles from the same batch?
- What is the tile’s lifespan or warranty?
A reliable dealer will provide documentation for all these details.
11. Order Extra Tiles (Always!)
Always order 10–15% extra tiles to account for:
- Cutting
- Breakage
- Future repairs
This ensures your replacement tiles match the rest of the floor.
Conclusion
Choosing the right tiles goes beyond color and design. Understanding tile quality, strength, thickness, certifications, and durability tests ensures your home remains beautiful and damage-free for years.
With this Tile Quality Checklist for Homeowners, you are now equipped to:
- Identify high-quality tiles
- Perform basic quality tests
