Kitchens:
It is impossible to provide a basic budget for a kitchen renovation. Besides the fact that kitchens vary so dramatically in size and shape, the prices of appliances, kitchen cabinets and countertops, from low end to high end have no commonality.
As an example, just one appliance - a cooktop can vary in price from $400 to $8,000.
