Installing an over the range microwave involves various factors that influence the final cost. As of 2025, typical installation costs range from $350 to $650, with high-end custom installations reaching $800 to $1,200. This guide provides a detailed breakdown of costs and considerations for trade professionals.
• Standard 30-inch units are generally less expensive than 36-inch professional models.
• Recirculating vents eliminate the need for ductwork but may require upgraded filters.
• Smart or convection models increase electrical load and may require cabinet modifications.
• New construction with open studs facilitates faster vent routing.
• Remodels may involve tile removal or cabinet trimming.
