Is tiling on stairs a good idea?
2 October 2025 · 4 min read
Tiled stairs are durable and dramatic — and unforgiving if the nosings, slip rating or substrate are wrong.
When tiled stairs work well
Solid concrete stairs, external steps and entrance flights are ideal candidates. The substrate does not move, the tiles take heavy traffic without wearing, and the finish cleans in seconds.
Internally, a tiled flight can carry a hallway floor upwards for a very cohesive result, particularly with Victorian geometric or terrazzo patterns.
Where we would advise against it
Timber staircases move. Even with a decoupling membrane and flexible adhesive, a bouncy domestic flight will eventually crack grout lines and loosen treads. If the stairs flex underfoot, tile is the wrong material.
Safety is not optional
Stair treads need a slip rating of at least R11 (or a pendulum test value of 36+), and every step needs a defined nosing edge. Standard building regulations also expect visual contrast on the step edge so the change in level is obvious.
We fit either a purpose-made stair-nosing tile or a metal profile trim. A bullnosed tile edge with nothing else is not adequate on a domestic flight.
