Go to good cabinet store and make use of their on site designer if you are going Ikea they help with design toofor both spaces, Make sure your contractor has already had an engineer check to see if moving walls is going to be an easy to do or very expensive to do and before you do anything have a budget

Most designers have a contractor they work with. I would not tackle this project without a designer! The contractor should be able to recommend one they work with and respect. If not how about checking a bath and kitchen design store, plumbing store or tile store who work with designers for a recommendation. You will save lots of money by avoiding design mistakes if you tackle this project correctly from the start. Don't try to skimp on you design process or you may encounter expensive mistakes along the way. Your kitchen and bath, both will add value to your home, do it with a professional for the best result.
