If you want a completely new kitchen, then you really need to get going now. It typically takes 3-6 weeks of planning and 1-2 months to install a new kitchen. That assumes all decisions are made before the installation begins and all the materials are on the job site. Don’t try this by yourself. Get the help of an interior designer, and don’t be surprised if your interior designer suggests bringing in an expert kitchen designer. That can save a lot of time and money.
