An R anti-slip rating is a way of measuring the suitability of a tile in terms of safety and slip resistance. The ratings range from R9 to R13, R9 being the lightest slip resistance and R13 being the most resistant. We’re here to explain where each R rating is appropriate so you can be sure you’re choosing the right tile for your project. So, what is an R rating?
The R in R rating stands for “Ramp test”, which is the test conducted when a tile is manufactured, to offer insight into its slip resistance. The number within an R rating indicates the level of slip resistance the tile has.
R9 Slip Resistance
Tiles with an R9 slip resistance are typically suitable for dry indoor spaces, e.g. living rooms, dining areas, bedrooms etc. If used across a bathroom floor, we highly recommend placing a bath mat, as R9 tiles will not offer sufficient slip resistance when wet.

R10 Slip Resistance
An R10 slip resistance offers a bit more grip, but we still only recommend for use within interiors. Tiles with an R10 anti-slip rating are ideal for areas that may be prone to splashes and spills like the kitchen or the cloakroom, but in rooms like the bathroom where there is likely to be excessive amounts of water, we would still recommend using a bath mat.

R11-R12 Slip Resistance
Tiles with an R11 or R12 anti-slip rating are suitable for outdoor spaces as well as indoor. We recommend that if you’re hoping to use an R11 or R12 outdoors, ensure it is made from porcelain, as these are much more durable and suited to floor designs. As for inside the home, they are suitable for use across wet rooms and bathrooms, offering a much stronger grip below foot for when you step out of the bath or shower.

R13 Slip Resistance
R13 is the highest level of slip resistance, and can be used pretty much anywhere! They are harder to come by as they are not necessarily needed in most residential areas, but are most commonly found used across swimming pools surrounds or public showers/changing rooms, where slip resistance is paramount for safety.
