The Bosch Series 8 CMG7241B1B is a built-in compact electric single oven with a full microwave function, designed to give you the versatility of two appliances in one 45cm-high unit. It’s very much a premium option, with Bosch’s top-tier Serie 8 design, sleek black glass and a modern TFT display.
With a 45-litre multifunction cavity, fan cooking, grill, air fry and a 900W microwave, it’s aimed at busy households that want maximum flexibility without sacrificing cupboard space. Smart Home Connect controls and Bosch’s Digital Control Ring add to the high-end feel.
A user score of 4.7 out of 5 from over a hundred reviews suggests owners are very happy, particularly with the cooking performance and convenience. It’s not cheap, but on paper it offers a lot more than a standard built-in oven or basic combi microwave.
This model is ideal for anyone fitting out a modern kitchen who wants full oven performance but doesn’t have room for two separate built-in appliances. If you’re short on space or planning a sleek bank of appliances, the 45cm height makes it easy to pair with another oven or warming drawer.
It suits households that cook regularly and like to mix things up – from quick midweek microwave reheats to proper roasts, traybakes and air-fried chips. The 45-litre capacity is generous for a compact unit, making it a good fit for couples and smaller families who rarely need a huge 70+ litre oven.
With its premium price and feature set, it’s best suited to buyers who value design, smart connectivity and finer control, rather than those simply after the cheapest built-in cooker. Confident home cooks will appreciate the range of heating options, while the clear TFT display and touch controls keep it accessible even if you’re not very techy.
If you’re renovating a kitchen and want a high-end, future-proof appliance that can handle almost everything, this Bosch fits the brief. If you barely cook or just want a basic oven for the odd pizza, it’s probably overkill.
The combination of a 45-litre multifunction oven and a 900W microwave in one cavity is a major plus, freeing up space while still giving you proper baking, roasting and grilling performance. You can go from defrosting to browning in the same appliance without juggling dishes.
Bosch’s Digital Control Ring and TFT display make the front panel feel intuitive despite the long feature list. Rather than endless buttons, you simply swipe and tap to choose functions and adjust settings, which is quicker and more precise than many traditional ovens.
The range of cooking methods is impressive for a compact unit: fan cooking, conventional heat, full-width grill, bottom heat, HotAir Gentle and a dedicated AirFry function. That gives you a lot of flexibility, whether you’re crisping chips, baking cakes or cooking a roast.
Cleaning Assistance using steam is another practical benefit. It doesn’t promise a full pyrolytic deep clean, but the hydrolytic steam action softens grease so you can wipe the enamel interior down far more easily than a completely manual oven.
Smart Home Connect support is a nice bonus. Being able to monitor and control the oven remotely, and access Recipe World guidance, adds convenience if you like connected kit and want recipes matched to the oven’s capabilities.
The premium design and feature set come at a premium price, so it won’t suit tighter budgets. You are paying for the Bosch name, Serie 8 styling and smart features as well as the combi functionality.
Capacity at 45 litres is generous for a compact, but it’s still smaller than a full-height single oven. If you regularly cook big roasts alongside multiple trays of sides, you may prefer a larger main oven or to pair this with a second appliance.
There’s only one shelf supplied for the main cavity, plus the grids and universal pan. For an oven at this level, it would be nice to see more rack options included out of the box, especially if you often cook on multiple levels.
Although it has a microwave function, there’s no turntable. That’s normal for many built-in combi ovens and helps with larger dishes, but microwave newbies may need a short adjustment period to using racks and dishes differently to ensure even heating.
Installation requires hard wiring by an electrician and the power draw is 3600W with a 16-amp fuse rating, so you may need to factor in professional fitting and potentially check your existing kitchen circuit.
Day to day, the Bosch Series 8 CMG7241B1B is designed to feel more like a premium appliance than a standard oven-microwave combo. The black glass front, glass control panel and clean TFT screen give a seamless look that blends well into modern cabinetry.
The drop-down door and 45cm height make access straightforward, even when built into a tall housing. The 45-litre cavity provides decent depth and width (480mm wide, 392mm deep), so standard baking trays and larger dishes fit without fuss. The included universal pan and two combination grids cover most common cooking setups.
Using the oven is largely menu-driven. The touch-sensitive Digital Control Ring lets you quickly dial in temperature, time and function while the TFT display spells out what’s going on, which is reassuring if you’re trying less familiar settings such as HotAir Gentle or AirFry. The integrated clock and programmable timer make it easy to schedule dishes to start and stop when you want.
Cleaning is less of a chore thanks to the hydrolytic Cleaning Assistance. Adding water and running the steam-assisted clean helps lift baked-on residue from the enamelled steel interior, so you usually only need a wipe rather than intense scrubbing. The glass interior and single light give a clear view of food as it cooks.
Safety-wise, the childproof lock, residual heat indicator, door contact switch and automatic safety shut-off provide peace of mind in family kitchens. Once it’s professionally wired in, everyday use is simple and feels reassuringly solid, in line with Bosch’s German-made reputation.
As a multifunction oven, the CMG7241B1B offers a broad toolkit for different cooking styles. Fan cooking and HotAir give even heat circulation for baking and roasting, while conventional top and bottom heat are better for more traditional recipes. HotAir Gentle is tuned for lower-energy cooking and more delicate dishes, helping to prevent drying out.
The integrated 900W microwave function means you can reheat, defrost and cook faster than with an oven alone. Combined cooking – for example, using microwave power to speed up the centre of a dish and then switching to grill or HotAir for browning – is where combi ovens really shine, cutting cooking times while still giving a good finish.
The AirFry function is a standout feature, essentially turning the oven into a large-capacity air fryer. Using high-speed circulating hot air and appropriate cookware, you can get crisp results on chips, nuggets and vegetables with less oil than deep frying, and with more space than most countertop air fryers.
Smart connectivity via Home Connect adds another layer. You can start, stop and monitor the oven from your phone, receive notifications and tap into Bosch’s Recipe World, which suggests settings matched to the oven’s capabilities. For busy households or those who like a little guidance, this can genuinely make life easier.
Supporting all of this are thoughtful details such as the Electronic programmable timer, clear TFT display and the lack of a turntable, which maximises usable space and allows for more flexible dish sizes. With just one cavity and one main shelf, it’s not built for huge multi-tray banquets, but for everyday cooking it delivers fast, even results with plenty of options to experiment.
This is a premium appliance, and the price reflects that. You can certainly find cheaper built-in ovens and more basic combi microwaves, but very few combine a 45-litre multifunction oven, 900W microwave, air frying, steam-assisted cleaning and full smart connectivity in one compact unit.
The strong user rating of 4.7 out of 5 from a substantial number of reviews supports the idea that buyers generally feel they’ve had good value, especially in terms of performance, build quality and convenience. The German manufacture and Bosch Serie 8 positioning add reassurance if you’re investing in a long-term kitchen fit-out.
The 2-year manufacturer warranty is decent but not outstanding at this price level. That said, Bosch’s reputation and the robust specification mean it should comfortably outlast the warranty when looked after properly.
If you mainly need a simple oven for occasional use, the cost will be hard to justify. But if you’re designing a compact, high-end kitchen and want one appliance that can genuinely replace both a main oven and a microwave while adding air frying and smart features, the overall package represents fair value for money.
The Bosch Series 8 CMG7241B1B is a sophisticated, space-saving solution for anyone who wants a serious cooker and a capable microwave wrapped into one elegant built-in appliance. Its 45-litre cavity, wide range of heating modes, 900W microwave power and dedicated AirFry function make it far more versatile than a standard compact oven.
Everyday usability is strong thanks to the Digital Control Ring, TFT display, steam-assisted Cleaning Assistance and well thought-out safety features. Smart Home Connect integration and Recipe World round out the experience, particularly for those who like connected tech and guided cooking.
It is undeniably a premium purchase, and the 45-litre capacity plus single supplied shelf won’t suit those who frequently cook for large crowds. But for couples, smaller families and style-conscious renovators looking to maximise performance from a 45cm niche, this Bosch Series 8 model is an excellent, well-reviewed choice that should serve you very well for years.
