As part of the kitchen/dining/living remodel, we also changed the stairs to flow with the rest of the remodel. We lengthened the treads so they were deeper and easier to walk up or down. The posts and grabber rail are fir with clear varnish. The cables are stainless steel. The stairs now meet current building codes. The stair treads are luxury vinyl plank, as is the nosing that matches. Treads and risers are the same luxury vinyl planking.
