Install an over-the-range microwave oven.... Most OTR microwaves are just under 30 in. wide; heights vary from about 10 to 18 inches and depths vary from 12 to about 18 inches. You need to choose a model that allows adequate clearance above the range but can be installed at a comfortable height.
Create new space in your kitchen. Free up counter space by swapping your countertop microwave for an over-the-range model. Then turn a slice of cabinet space above the microwave into an attractive display shelf.
Open shelves eliminate the heavy look of closed cabinetry and lighten up small spaces. Closed base cabinets provide storage for utilitarian, not-so-display-worthy pieces while keeping the visual bulk below eye level. Placing the microwave above the range frees valuable counter space for cooking while keeping it out of kids' reach.
