Anti-Slip Tile Ratings and Grades – R13-R9 Explained

Posted by ANGELA COYLE | Wednesday, June 27, 2018

When browsing for tiles you’ll likely come across the “R” rating system. This is the letter R followed by a number (13, 12, 11, 10 or 9).  But what does each number mean, and how can it assist you in purchasing the right tiles to suit your needs?

In the blog, we’ll explain the R rating system, suggest where each rating can be used, and even give examples of R9-R13 tiles so that you know what’s currently available to purchase.

The ‘R’ rating system indicates an anti-slip finish

This letter and number combination indicates the level of the anti-slip finish. Not all tiles will have a slip ratings, but tiles that have been designed to provide grip often will. The ‘R’ stands for ‘ramp test’, with the subsequent number indicating it’s anti slip grade - 13 being strong, 9 being slight.

R13 Non Slip Tiles

The R13 rating is the highest slip resistance rating for anti-slip floor tiles. – It’s usually recommended for areas which are exposed to water for the majority of time, such as patios, swimming pools and surrounding areas, SPAs and saunas, as well as kitchens in some cases.

DOs: Use for areas such as jacuzzi floors, wet ramps and walk through pools, as well as commercial areas where floors need to meet minimum legal standards.

DON’Ts: Be tempted to buy R9 or R10 rated tiles for high-traffic wet areas even if you prefer the design.

Example Product: The Delas range features large R13 non slip tiles made from hard-wearing porcelain. Combining a natural stone effect with modern style, these floor will look perfect both indoors and outdoors.

R12 Non Slip Tiles

This category includes most unglazed tiles and some glazed ones, and is generally regarded as safe for installation in areas such as kitchens, bathrooms and hallways, as well as commercial areas of various sizes, from communal showers and lavatories, pool sides and changing rooms to hotel foyers, shopping centres and airports.

DOs: Use tiles made from porcelain both outdoors and indoors as a sturdy flooring option for areas where you’re looking to create a seamless kitchen-to-patio or garden transition.

DON’Ts: Don’t rely on R12 tiles to prevent slipping if used on excessively steep slopes. If you’re tiling a commercial space and want to protect yourself against injury claims, opting for R13 tiles is the safest option.

Example Product:  A bestseller for commercial areas, the Dotti corund range has a R12 slip resistant rating and is ideal as non-slip floor tiles in places like commercial kitchens and store rooms. These non-slip porcelain tiles are also suitable for external situations.

R11 Anti-Slip Tiles

Similarly to the R12, floor tiles in the R11 anti slip category are considered to be secure for both dry and wet environments, which makes them perfect for use in home environments varying from damper areas such as bathrooms and kitchens, to hallways and even living rooms.

You should also consider having R11 tiles if you are installing office floors, as they are both hard wearing, saving you money on floor replacements, and sturdy, saving you money on minor injury claims.

DOs: Make the most of the textured anti slip finish and create beautiful (and safe!) outdoor areas throughout your patio and garden.

DON’Ts: Don’t go below R11 if you are tiling wet rooms, as they might be unsafe to walk on barefoot in the presence of water and soap.

Example Product: The Clarens range of grey anti slip tiles made from quality porcelain and ideal both for busy family homes and for some commercial environments. The R11 rated tiles are also suitable as exterior floor tiles if you want to add a stylish contemporary touch to our outdoor spaces.

R10 Anti-Slip Tiles

Often used to prevent slippage in domestic situations, the R10 tiles will be perfect for kitchens and bathrooms. Thanks to their anti-slip properties, they can also be used as external floor tiles (porcelain versions only) or commercial tiles.

While R10 rated tiles will usually be glazed matt tiles which will act as anti-slip when wet, you might also find some unglazed tiles in this grade. In addition to bathrooms (where they should be used in combination with a bathmat) and kitchens, R10 tiles are also a good fit for living rooms and hallways, where occasional spills and wetness can occur.

DOs: Install in internal domestic settings where the floors are subjected to occasional wetting such as bathrooms, utility rooms and kitchens.

DON’Ts: Don’t be tempted to use these as a cheaper option in areas where increased friction and high slip resistance is required.

Example Product:  R10 anti slip tiles like the ones from the Magma range are an ideal choice for areas where a durable floor is desired.

R9 Slip Resistant Tiles 

The R9 tiles exhibit lower amount of anti-slip properties compared to the higher ratings. R9 is the lowest rating for anti-slip tiles, meaning they are fine for domestic environments and, if they made of porcelain, some commercial environments where anti slip properties are not really required. 

Full body porcelain tiles like the Dotti R9 is very popular for newsagents, car showrooms and shops. Quarry tiles can be used outdoors, because of their construction and frost resistant properties, but care needs to be taken when wet.

DOs: Use in dry areas where the floors are rarely, if ever, exposed to water, such as dining areas and hallways.

DON’Ts: Ideally, R9 tiles should not be used outdoors or in wet environments.

Example Product:  Our range of quality quarry tiles are perfect for use in bathrooms, kitchens and hallways, provided that there’s minimal exposure to water. Great in both interior and exterior spaces, or even as commercial tiles, thanks to their hardwearing finish.
