Grip
The R number is tested with shoes on a tilting ramp. Higher means less slippery when wet.
R10 also works on balconies and outdoors.
For bare feet there is a separate test, A to C:
Which tile where.
Updated 29 October 2026
Grip where it gets wet, strength where it gets walked on, size where you want calm. What matters, room by room.
Three things decide
What the figures on a tile mean.
Water
How much water a tile soaks up. Less water means no frost damage, fewer stains and a stronger tile.
Porcelain goes anywhere, inside or out. Wall ceramic stays on indoor walls.
Thickness
Thicker tiles carry more weight; thin slabs are light enough for walls.

Living rooms and floors
- GripR9 or R10 is enough indoors
- WaterAny porcelain
- Size60 × 120 and larger
Big tiles make a room feel calm and bigger, with fewer joints to clean. Matt hides footprints and dust; polished reflects light into a dark room.
Bathroom walls
- GripNot needed on walls
- WaterPorcelain or wall ceramic
- SizeSlabs or small decors
Walls are where you can play: a single slab behind the basin, a textured decor in the shower, or mosaic in a niche. A slab means no grout lines where water runs.
Bathroom floors and showers
- GripR10, and barefoot B in the shower
- WaterPorcelain, under 0.5%
- SizeSmaller near the drain
A walk-in shower floor slopes to the drain, so smaller tiles or a cut slab follow the fall better. Pick a matt or grip finish for wet bare feet.
Kitchens
- GripR10 on the floor
- WaterPorcelain resists oil and stains
- Size12 mm slabs for worktops
One material can cover the floor, the wall behind the hob and even the worktop. Porcelain takes heat, acids from lemon and vinegar, and hot pans.
Balconies and outdoors
- GripR10 or R11
- WaterPorcelain, frost proof
- Size20 mm on gravel or supports
Outside, tiles meet rain, sun and the odd frost. A grip finish keeps them safe when wet. 20 mm tiles can sit on gravel or raised supports, with no glue.
Pools
- GripBarefoot B around, C on steps
- WaterGlass mosaic inside the pool
- Size2.5 cm mosaic on mesh sheets
Glass mosaic lines the pool itself: it takes chlorine, follows curves and keeps its colour. Around the pool, use a grip porcelain rated for bare feet.
Good to know
Do porcelain tiles need sealing?
Matt and glazed porcelain do not; they take in almost no water. Some polished tiles get a protective treatment at the factory. Ask us about the tile you choose.
Can I lay tiles over underfloor heating?
Yes. Porcelain carries heat well. Your fitter uses a flexible adhesive and lets the heating cure the screed first.
What does "rectified" mean?
The edges are ground straight after firing, so joints can be as thin as 2 mm. Large tiles and slabs are almost always rectified.
How many extra tiles should I order?
About 10% for straight laying and 15% for diagonal or herringbone, for cuts and breakage. Keep a box for future repairs: later batches can differ slightly in shade.
Can I use the same tile inside and outside?
Often yes. Many series, such as Midi, come in a normal finish for indoors and a grip finish for outside, in the same colour.
