When choosing floor tiles, many people focus on color, size, or price. In real daily use, however, the key factor that determines walking safety often comes from a less noticed technical measure: the slip resistance R rating (R-rating) or the COF (Coefficient of Friction).

These are essential standards in the building materials industry and directly impact safety in wet or moisture-prone areas such as bathrooms, gardens, kitchens, and swimming pool zones.

1. What is the R rating? Why are anti-slip tiles graded from R9 to R13?

Under international standards, the R9–R13 scale reflects how slip-resistant a tile surface is:

R9: Low slip resistance, suitable for dry areas

R10: Medium slip resistance, suitable for living rooms and indoor walkways

R11: Good slip resistance, ideal for kitchens, terraces, and humid areas

R12–R13: Very high slip resistance, recommended for swimming pools, wet outdoor zones, and public spaces

The higher the R rating, the better the grip and the lower the risk of slipping and falling.

2. Why should you care about the R rating?
✔ Safer for the whole family

Tiles with a higher R rating increase friction and improve footing in wet conditions. This is especially important for:

• Homes with young children
• Elderly family members
• Areas that frequently come into contact with water

✔ Choosing the right tile for each area

Different spaces require different safety levels:

• Bathrooms and kitchens: R10–R11 tiles
• Gardens and porches: R11–R12 tiles
• Swimming pools and highly slippery zones: R12–R13 tiles

✔ Durable and easy to maintain

A micro-textured surface helps:

• Increase grip
• Reduce visible dirt
• Make cleaning easier
• Maintain long-term aesthetics
