The Bosch Series 8 CMG778NB1 is a built‑in compact electric single oven with an integrated 900W microwave, designed to give you full oven performance and rapid microwave convenience in one sleek 45cm unit.
Bosch’s Serie 8 range sits at the premium end of the market, and the price here clearly reflects that. In return you get a multifunctional cavity with 4D HotAir, grill, air fry, defrost, dehydration and more, plus both pyrolytic and steam (hydrolytic) cleaning.
With a 4.7 out of 5 rating from well over a thousand owners, this model is clearly doing something right for real kitchens. It’s aimed at buyers who want top‑tier build quality, smart touches and genuine space saving, rather than the cheapest way to put an oven in a wall.
The CMG778NB1 is ideal if you’re tight on space but don’t want to compromise on cooking options. With a 45‑litre capacity and 45.5cm height, it’s perfect for smaller kitchens, city flats, or as a second oven in a larger family kitchen.
It suits premium buyers who are happy to pay more for a high‑end finish, advanced features and the convenience of combining an oven and microwave in one appliance. If you’re planning a sleek, built‑in bank of appliances, this compact Serie 8 model will sit neatly alongside a full‑size oven or warming drawer.
Confident home cooks and keen foodies will appreciate the 4D HotAir, air fry and specialist functions like dehydration and gentle conventional heat. At the same time, the clear TFT display, touch controls and Digital Control Ring make it approachable for less experienced users who mainly want reliable, even cooking and straightforward presets.
If you rarely cook from scratch and just need a basic oven for the odd tray of chips, this is likely overkill. But if you cook most days, want to streamline appliances and value a modern, minimalist look, it’s right in the sweet spot.
The combination of full multifunction oven and 900W microwave in one 45cm built‑in unit is a huge win for saving space without losing flexibility. You can bake, roast, grill, reheat and defrost from the same cavity.
4D HotAir fan cooking distributes heat evenly across all levels, so trays of biscuits or roast veg cook consistently without constantly rotating them. That makes batch cooking and family meals far less fussy.
Self‑cleaning is a real highlight. Pyrolytic cleaning incinerates spills into ash at high temperatures, while hydrolytic steam cleaning helps loosen everyday grease. Together they mean far less scrubbing and harsh oven cleaners.
The Digital Control Ring with touch TFT display gives precise, modern control. Swiping to set temperature, time or function feels intuitive, and the clear screen makes it easy to see what’s going on at a glance.
Despite its compact size, the 45‑litre cavity with included trays, grid and universal pan is versatile enough for most day‑to‑day family dishes. Strong user reviews and Bosch’s reputation for solid German engineering add confidence.
The most obvious drawback is price: this is firmly a premium appliance, and many standard single ovens with separate microwaves will cost significantly less overall.
Capacity at 45 litres is generous for a compact unit but still smaller than a typical 60cm single oven. If you regularly cook very large joints or multiple big trays at once, you may find it limiting as your only oven.
There’s only one shelf supplied as standard, which feels a little stingy at this level and may mean buying an extra shelf if you like multi‑level cooking. The 2‑year warranty is decent but not exceptional for the price point.
Finally, it needs to be hard‑wired by an electrician and comes with a fair amount of technology and cooking options, so there’s a bit of a learning curve compared with a very basic dial‑controlled oven.
Day to day, the CMG778NB1 is designed to be as simple to live with as a feature‑packed oven can be. The touch control panel and Digital Control Ring are laid out clearly, so setting temperature, time and mode quickly becomes second nature. The TFT display provides crisp feedback, including timer information and selected functions.
The drop‑down door and wide 480mm internal width make it easy to slide in roasting tins and baking trays, despite the compact height. LED lighting inside the enamelled steel cavity gives a bright view of your food without having to open the door and lose heat.
Cleaning is where this model really stands out. For a deep clean you can run a pyrolytic cycle, which heats the oven to a very high temperature to reduce food residue to fine ash that’s easily wiped away. For lighter maintenance, the hydrolytic steam clean function helps soften grease and splashes, making a quick wipe‑down much easier.
The built‑in childproof lock, door locks and residual heat indicators add peace of mind in busy family kitchens. With no turntable to remove and wash, the microwave function also feels more like using a normal oven, with fewer loose parts rattling around.
As a multifunction compact oven, the CMG778NB1 offers an impressively broad set of cooking modes. 4D HotAir ensures even fan‑assisted heat throughout the cavity, while bottom heat and conventional heat options cater for more traditional baking and roasting styles. There’s also a gentle conventional setting for more delicate dishes.
The 900W microwave function delivers quick reheating and defrosting, with five power levels to suit everything from softening butter to rapidly heating leftovers. Because there’s no turntable, you get a flat, more flexible cooking surface, and it works more like a standard oven with added speed.
On top of the basics, Bosch includes modern extras to broaden what you can cook. An air fry mode gives you a healthier spin on chips and breaded snacks, using hot air rather than deep oil. Dehydrate functions can be used for drying fruit or herbs, and dedicated defrost settings help bring frozen ingredients up to temperature evenly.
Control is handled by the Digital Control Ring and touch TFT display, which are hallmarks of the Serie 8 range. They make it easy to select functions and set precise times or start/stop schedules. Voice control support adds another layer of convenience for connected homes, letting you integrate the oven into smart routines where supported.
Safety has clearly been considered, with childproof locking and both electronic and mechanical door locks. The heating‑element grill, LED lighting and robust enamelled interior all reinforce the sense of a carefully engineered, high‑end appliance built to cope with frequent use.
This Bosch sits at the premium end of the compact oven category, and the price reflects that. You’re paying not just for the Bosch badge, but for the combination of a full‑featured oven, 900W microwave, advanced fan technology and dual self‑cleaning options in a single built‑in unit.
If you were to buy a separate quality microwave and oven, you could likely spend less overall, especially if you drop down a tier on features. However, this model’s strength is in the way it condenses two appliances into one, frees up cabinetry and looks seamlessly integrated in a modern kitchen.
The strong 4.7/5 user rating from a very large number of reviews suggests owners generally feel it delivers on its promise, which supports the case for paying more. If you’re simply chasing the lowest price per litre of capacity, it won’t stack up. But if you value space saving, design, convenience and a seriously capable spec sheet, it offers solid value for a premium choice.
The Bosch Series 8 CMG778NB1 is a sophisticated compact oven-microwave that brings full‑size functionality into a smaller footprint. With 4D HotAir, air fry, grill, 900W microwave power and both pyrolytic and hydrolytic cleaning, it’s far more capable than most compact ovens and genuinely replaces a separate microwave.
It’s not a bargain buy and the 45‑litre capacity won’t suit those who depend on a single, very large oven for big family roasts every weekend. The limited number of shelves and only average warranty also remind you that you’re paying mainly for technology, flexibility and design.
For style‑conscious households fitting a premium kitchen, or keen cooks who want a versatile second oven that doubles as a microwave, this model is an excellent choice. If your budget stretches to it and you value convenience and space saving over sheer capacity, it’s one of the standout compact options currently available.
