Installing your wall oven in a cabinet ensures that there is enough room for the oven cavity and its electrical components. A cabinet customised according to the oven size dimensions will give maximum benefits in terms of support. However, while cabinets are the most preferred option, you can also opt to install the oven in a built-in wall cavity if your kitchen layout already has one or allows for one. By creating such a built-in wall holder for your oven - you can ensure that the wall oven takes up less space as it is safely tucked in a corner of your kitchen.
