There are several common places to put a microwave in a kitchen, depending on the layout of the space and personal preferences. Here are some options to consider:

1. Countertop: The most common place to put a microwave is on a countertop, which makes it easy to access and use. Make sure you have enough counter space and consider the height of the microwave for easy use.
2. Over the range: Another popular option is to install a microwave above the range, which can save space and keep the microwave at eye level. This requires a special installation kit and should be done by a professional.
3. Built-in: A built-in microwave can be integrated into your kitchen cabinets, providing a seamless look and freeing up counter space. This option requires more planning and installation than a countertop or over-the-range microwave.
4. Microwave cart: If you have limited counter space or want to move the microwave around, a microwave cart can be a good solution. This is a freestanding unit with wheels and shelves that can hold the microwave and other kitchen items.

Ultimately, the best place to put a microwave in your kitchen depends on your individual needs and preferences. Consider factors like available space, usage patterns, and the overall layout of your kitchen when deciding on the best location.
