Bosch built-in combi microwaves put a microwave and an oven in one compact appliance. That makes them a good fit if you want a second oven at eye level, or one appliance that can reheat quickly as well as bake and roast. The range covers two series. Series 4 is the more straightforward choice, and Series 8 adds more features.

Series 4 models have a 44 litre cavity, a 36 cm turntable and 900 W of microwave power. You can combine the microwave with the grill or with convection, so food browns as it cooks. They use retractable rotary dials alongside touch controls, come in black or stainless steel, and need cleaning by hand.

Series 8 models move up to 45 litres with three shelf levels and inverter heating. Inverter heating delivers a steadier, lower power rather than switching on and off, which helps with even defrosting and gentle reheating. All Series 8 models have a TFT display with a digital control ring. Most connect to Home Connect, so you can use some features from an app. Cleaning varies within the series, from steam cleaning to partial catalytic and hydrolytic, up to pyrolytic models that burn off residue at high temperature.

To narrow it down, start with the series. Choose Series 4 if you want simple controls and a choice of finish. Choose Series 8 if shelf space, inverter heating or easier cleaning matter more, then pick the cleaning method. For microwave-only models, see Bosch built-in microwave ovens.
