The Bosch Series 4 CMA583MS0B is a built-in combination microwave designed to sit in a 45cm high cabinet and double up as a compact oven and grill. With a generous 44-litre capacity, hot air cooking and 900W microwave power, it is meant to handle everything from quick reheats to full family meals.
Bosch positions this as a solid mid-to-premium option in its built-in range, with more versatility than a basic microwave but without the price tag of high-end smart ovens. The stainless steel finish and drop-down door are clearly aimed at modern fitted kitchens.
With a strong 4.7 out of 5 rating from more than 1,600 owners, it is clearly popular. The specification suggests a capable all-rounder that could realistically stand in for a second oven in a busy household.
This model is ideal for medium-sized households that want a built-in microwave which can genuinely cook, not just reheat. The 44-litre cavity and 36cm turntable give you space for family-sized dishes, casseroles and large plates, so it suits everyday use rather than occasional snacks.
It is a good fit for anyone planning a new kitchen or upgrading to a more flexible oven setup. If you already have a full-size oven below, this makes an excellent secondary appliance for side dishes, quick bakes and midweek meals, especially when you do not want to heat a large cavity.
Budget-wise, it sits in the mid to upper range for combination microwaves. It is not a budget buy, but you are paying for Bosch build quality, convection oven functionality (80–240°C), hot air grilling and multiple automatic programmes. That makes it best suited to people who cook regularly and will make use of the extra features.
If you are a first-time buyer of built-in appliances but want something that is straightforward to use, the mix of dial and touch controls plus AutoPilot 15 programmes will help you get good results without constant guesswork.
The 44-litre capacity is larger than many built-in microwaves, giving plenty of room for oven dishes, roasting tins and large plates. Combined with the 36cm turntable, it is practical for family cooking, not just warming leftovers.
With 900W of microwave power and a 1750W grill, it cooks and browns food quickly and evenly. The convection oven function with an 80–240°C range means you can bake, roast and crisp like a standard oven, but in a more compact space.
AutoPilot 15 automatic programmes and auto cook/defrost functions take away much of the trial and error. Select the type of food and weight and the oven sets the time and temperature for you, which is helpful if you are not an experienced cook.
Touch and dial controls strike a good balance between precision and ease of use. Combined with a clear timer and a control panel lock, it is practical for everyday family use and safer around children.
Bosch’s reputation for reliability, the stainless steel interior and a 2-year manufacturer warranty add peace of mind. The excellent 4.7/5 user rating from a large number of reviews reinforces that owners are generally very satisfied.
This model needs to be hard-wired by an electrician and does not come with a plug or cable, so installation costs will be higher than for a simple freestanding microwave.
At a premium price for the category, there are cheaper combination microwaves available. If you only need basic reheating and the odd jacket potato, the extra oven and grill functions may be more than you require.
There are five microwave power levels, which is adequate but not especially generous. Some keen cooks may prefer a finer level of control.
The drop-down door is great above a built-in oven, but if fitted very high in a tall housing it can be a stretch for shorter users when lifting hot dishes in and out.
Day to day, the Bosch Series 4 CMA583MS0B feels more like a compact oven that happens to have a microwave built in than the other way round. The drop-down door gives you a stable surface to rest dishes on as you load and unload, which is handy when dealing with heavier casserole dishes or trays.
The combination of a rotary dial and touch buttons keeps operation simple. You can quickly set the power and time for basic microwave jobs, but have finer control when using the convection oven or grill functions. The clear timer makes it easy to see how long is left at a glance.
The stainless steel interior not only looks smart but is easier to wipe down than painted cavities, especially after grilling. The 36cm turntable is large yet removable, so you can take it out for cleaning or for using larger, non-rotating dishes with hot air cooking.
Built-in at eye level, it is very convenient for checking on food without bending. However, because it has to be hard-wired and installed into a 59.4cm wide, 45.4cm high cabinet, it is best suited to planned kitchens rather than quick plug-in replacements.
Performance-wise, the 900W microwave output is strong enough to heat food rapidly and evenly, particularly when combined with the large 36cm turntable to minimise cold spots. Five power levels give you quick options for gentle defrosting, reheating and full-power cooking.
The integrated convection oven with an 80–240°C temperature range is a major advantage over standard microwaves. It allows proper baking, roasting and crisping of foods that would otherwise be soggy, such as chips, breaded chicken and pastries. Hot air grilling adds another layer, combining fan heat and grill to ensure joints of meat, gratins and vegetables cook through while browning nicely on top.
AutoPilot 15 automatic programmes are a highlight. These built-in recipes adjust time and temperature automatically based on the chosen programme and food weight, helping you achieve consistent results with minimal input. The auto cook and auto defrost functions are particularly useful for busy weeknights when you want to get food on the table quickly.
Safety and convenience have been considered too. The control panel lock helps prevent accidental changes or curious children from tampering with settings. A built-in timer and clear control layout make it straightforward to coordinate dishes with a main oven.
Behind all of this is Bosch’s typical build quality, seen in the stainless steel cavity and solid drop-down door. For a 45cm high built-in appliance, the feature set is comprehensive, comfortably covering the needs of most households who want one appliance to microwave, bake, grill and roast.
This Bosch combination microwave sits at the premium end of the price range for microwaves, reflecting its built-in design and full oven capability. You are paying more than for a simple freestanding model, but you are getting a genuine multi-function cooking appliance rather than a one-trick microwave.
When you factor in the 44-litre capacity, convection oven with hot air, 900W microwave power, 1750W grill and 15 automatic programmes, the specification is strong enough to justify the higher price for many buyers. It can realistically replace a second oven, which may save space and money in a new kitchen layout.
The excellent 4.7/5 rating from well over a thousand users suggests most owners feel they have had good value over time. If your priority is the lowest possible upfront cost, there are cheaper options. But if you want a flexible, built-in combi appliance from a trusted brand, this model offers solid value for its feature set and build quality.
The Bosch Series 4 CMA583MS0B is a well-rounded, built-in combination microwave that comfortably doubles as a compact oven and grill. Its 44-litre capacity, strong 900W microwave performance and full convection functionality make it far more versatile than a standard microwave.
It is best suited to households investing in a fitted kitchen and wanting a reliable, flexible second oven at eye level. The automatic programmes and straightforward controls keep it approachable, while Bosch’s build quality and stainless steel interior promise years of use.
You do pay a premium and need professional installation, so it is not the right choice if you only need basic reheating or are on a tight budget. For everyone else, particularly families and keen home cooks short on oven space, it is an excellent, highly rated option that earns its place in the kitchen.
