Enter the over-the-range (OTR) microwave oven – a sophisticated solution that marries the convenience of microwave cooking with the essential capabilities of a range hood. These appliances offer a streamlined, integrated look, freeing up precious counter space while tackling cooking and ventilation needs above your stovetop. But with a myriad of options available, how do you choose the perfect OTR microwave to elevate your culinary experience and fit seamlessly into your home? This comprehensive guide will walk you through everything you need to know.

What is an Over-the-Range Microwave? Understanding the Basics

An over-the-range microwave is a versatile kitchen appliance uniquely designed to be installed above your cooktop, typically replacing a traditional range hood.
