I am re-facing my stairs as several others have posted about (tinan and noellabelle come to mind). I will be laying oak flooring on the landing as well. Plan to keep the oak treads and flooring unstained/poly coated, but final finish will be tested on scraps before that decision is made. All wood (oak treads and flooring and painted risers) are cut and sanded/painted. Five of the 13 steps/risers are installed. I didn't attach the first tread or the risers above and below it as I'm still contemplating how to finish the right edge of the tread.

Attached is a picture of the first step looking down at it. You can see how I wrapped ithe tread around the wall on the right. Since the tread sticks out farther than the wall, I thought this would make it seem more intentional and a bit more finished. It does to a certain extent, but the completely flat edge lacks the grace of a bullnose. Can a router be used to create a bullnose on that one inch (she asked because she has never used a router before)? I know the created bullnose on the right would still be end grain.

Alternative is to cut off the return I made and buy a pre-formed bullnose oak return. It's only a couple of dollars (literally 2 bucks and change), but I wonder about 2 things: attach by routering a groove in the return and a groove in the side of the tread and connect with a spline and adhesive? Won't that attached 1-inch joint be weaker than the way the tread is now contoured?

I appreciate your help with this latest twist!
