Measure the space where you plan to put your microwave prior to purchasing the appliance.

Countertop microwave ovens. These take up counter space but are typically cheaper and easier to install than the other two options. Over-the-range microwave ovens. Microwaves in this category are vented to the outside and typically require installation by an electrician. On the plus side, they free up counter space. Built-in microwave ovens. These are designed to be built into a wall or surrounded by cabinetry. They are a great option if you don’t have counter space, since they can be installed in a microwave drawer under the countertop and they can glide out when you need to warm your food. They are more expensive, ranging from $350-$1500, but can look more streamlined than the other types. Some countertop microwaves will have a build-in option.

Thoroughly inspect any used microwave you are considering purchasing. Ask the seller if they can demonstrate that the microwave works, and look to buy a microwave from a seller who offers at least a 14-day return policy.
