R11 Anti-Slip Tiles: Where to Use Them & Popular Designs

Let’s explore what R11 means, where it can be applied, and four of our popular Studio R11 porcelain tile collections.

What is R11? 

R11 is a slip-resistance classification for floor tiles, indicating a higher level of slip resistance compared with lower-rated surfaces such as R9 and R10.

The “R” rating comes from the ramp test, where tiled surfaces are tested under wet conditions to determine their slip resistance. The rating ranges from R9 to R13, with a higher number indicating greater slip resistance. R11 tiles are therefore often considered when additional underfoot grip is required, particularly in areas that may be exposed to moisture, water or heavier use.

Where Can R11 Tiles Be Applied?

R11 tiles are a popular choice for areas where greater slip resistance is required, particularly in spaces that may be exposed to water, moisture or frequent foot traffic. Their enhanced grip makes them suitable for a variety of residential, commercial and outdoor applications. They can be used across a range of indoor and outdoor applications, including bathrooms, pool surrounds, balconies, terraces, walkways, entrances, restaurants and other commercial spaces.

Where Performance Meets Design – Studio R11 Collections

Let’s explore 4 Studio collections that deliver high-performance R11 slip resistance without compromising on aesthetics.
