I removed carpeting from a set of stairs going down to a basement. The structure of the stairs is just plywood on stringers, but is fully boxed in, meaning it is built out with both risers and treads.
To re-cover the stairs I am wondering what my options are? My preference would be for something slip resistant, waterproof and relatively quiet. Cost is no object and the absolute highest quality commercial option would be preferable. I want the best of the best.
