ᐅ Which covering is suitable for a concrete staircase?

In our new build, there is a granny flat on the upper floor, which can be accessed via a separate exterior entrance and then a concrete staircase leading upstairs. Now we need to decide on a stair covering. Initially, I thought of tiles, but they have grout lines that will eventually get dirty. The builder suggested granite, but that is probably more expensive. Does anyone know the typical price range? Are there any recommended resources for this?

I wouldn’t recommend using granite just for a separate apartment. However, in a shared stairwell with you, it makes more sense because then you get to see something nice there more often.

We received two price quotes: one supplier asked for 3,000 net just for the materials (half turn, 15 steps). The supplier we chose offers the entire job for 3,000 net including labor. He was also hired for additional natural stone work (entrance, window sills, etc.).

Visit a large building supply store to see what you like—wood, tiles, and so on.

The covering must be 2 cm (0.8 inches) thick because the staircase has just been shuttered, and they needed to know the thickness of the covering for that.
