Think about how you can function without a working kitchen. Utilize small appliances and keep your pantry stocked with nonperishable grab-and-go items. Use biodegradable plates, cups, and utensils since you won’t have a working dishwasher. Take advantage of a grill or outdoor cooking area if you have one. You may also want to consider eating out with family or friends more often. Being prepared ahead of time will greatly alleviate any stress you may have without a functioning kitchen during the remodel.
If you decide to go with a major remodel and spend upwards of $50,000, you should consider consulting a kitchen designer. A professional designer has the experience, connections and examples to suggest what fits with your plan. He or she can also help you save where possible, so you don't spend needlessly while still getting the final product you want.
