Warming drawers are typically inexpensive to install in existing kitchen cabinetry. They are usually found in standard kitchen cabinet widths of 27 inches and 30 inches. Factors such as size, finish, placement, features and safety all affect installation costs.
Standard warming drawers operate and fit just as functionally as any other sliding drawer. Flexible placement allows the unit to be installed separately and/or near other appliances. Smaller size with fully extended drawers are easiest to install and allow safe transport of food. Device functions such as controls, crisp settings and removable racks increase price of the unit and possible installation costs dependent upon model specifications. Finishes such as cabinet panel fronts and trim also raise unit price and possible installation costs.
Some ranges have a warming drawer below the main oven. This space-saving ingenuity cuts additional installation costs.
