Anti-Slip Tiles for Bathrooms and Outdoor Areas – What Do R9, R10 and R11 Mean?

Anti-Slip Tiles for Bathrooms and Outdoor Areas – What Do R9, R10 and R11 Mean?

Why Slip Resistance Matters

Slip resistance indicates how well a floor surface grips under wet or humid conditions.
 It’s measured according to the DIN 51130 standard, which defines slip-resistance classes from R9 to R13.
The higher the number, the stronger the grip.

Here’s a general overview:

  • R9: Low slip resistance – for dry indoor spaces such as living rooms or hallways

  • R10: Medium slip resistance – ideal for bathrooms, kitchens or semi-covered outdoor areas

  • R11: High slip resistance – perfect for terraces, pool surroundings and other high-moisture areas

Anti-Slip Tiles for Bathrooms

Bathrooms are naturally humid spaces.
 A higher slip-resistance rating such as R10 or R11 is recommended, especially for walk-in showers or floors with a slope.
Tiles rated R9–R10 provide a good balance between safety and easy cleaning, while R11 tiles are ideal for spa or wellness areas.

Anti-Slip Tiles for Gardens and Terraces

Outdoor areas require more durable materials.
 Rain, frost and leaves can make surfaces slippery, which is why R11-rated tiles are the safest option.
Opt for 2 cm thick porcelain pavers, as they are frost-proof, easy to maintain and highly resistant to weather changes.
