Hi , what kind of style do you like ? A picture of your kitchen ? I had an ugly miss matched 1970's and turned it into a vintage cottage style , with a little rustic industrial ... I glued beadboard to the front of my cabinet door and painted my cabinets white . I painted my butcher block formica a deep charcoal . I got inexpensive ( but good quality ) peel and stick wood look vinyl planks for my flooring. I bought a vintage style faucet. A total transformation !
