Kitchen size would dictate, but I find shelving, provided it is not too deep, is more accessible than sliding units. I also live with people who don't know how to close things.

I think the colour used on these cabinets is great. This is a colour which is unlikely to unsettle anyone who sees it and is teamed with very neutral walls and furnishings. This room looks modern, with a little retro or Scandinavian twist.I believe that if you really love a particular colour, why not use it as a colour block on cabinets. Just keep the main elements in the room neutral and the accent colours to a minimum, like the orange accent used here.

It would not be unusual to have black knobs, handles etc and different hinges. It is personal preference though.

The front of your home looks like homes in Las Vegas, Nevada. Are you more interested in a bathroom along these aesthetics? In Australia the bathroom you have shown would be a very common look. If you are staying in the home for a length of time, and your budget meets your wishes. Then change it to whatever you would feel more comfortable with.
