I currently have wooden stairs and I am replacing the carpet in my home with laminate and in some rooms hardwood. Can I use the leftover laminate on my stairs? If not, how hard is it to replace the carpet on my stairs with tile? I saw tile steps before but I am not sure if it was ceramic or marble.

To do this and stay in code want happen, and you can take the treads of and then lay the tile because there nothing left to lay the tile on. If you lay the tile on the treads it will throw the rise of the steps off. Id stay away from doing this
