My flooring installer's price for the stairs seems ridiculously high to me: he orders in the stair treads from another supplier, I believe. The product will be better than the DY kits from home depot, but not worth what he's charging (I'll end up with a $5000 staircase if I go with him, however this does include sanding down and staining-to-match the banister and a few other pieces of wood). My plan is to paint the light oak banister, and build and install the floor treads myself. The risers will be easy: they will be painted ivory so its just a matter of picking out the wood, cutting, painting, and installing them. I need advice on the treads. My first thought was, using the hardwood flooring strips, build each tread and install it as a unit. However, why wouldn't I just install the individual pieces, fit together tongue in groove, with the last piece bullnosed as it is the front of the tread. This seems too easy, so there must be more too it. Is there? Where might I encounter difficulty? Any advice would be appreciated.
