We just finished a small reno on our place. We had 4 different kinds of flooring on our main (carpet, hardwood, tile & linoleum) and replaced it all with vinyl plank. We also replaced the carpeted common area upstairs with vinyl. For the stairs we went from carpet to square edge vinyl nosing with white risers and 1/2x12 skirts running up the sides to tie into the baseboards. Some other details we did was replace the tired old baseboard with 1/2x8 on the main and 1/2x6 in the common area upstairs. We also replaced all the handrails with a new profile, went from wood brackets to metal and where we had spindles, we went from square wood to round black metal ones.
Really happy with the overall look.
