Building in: which size do you need?
A built-in microwave goes into a kitchen cabinet and keeps your worktop clear. The measurements are exacting: almost all models are made for a recess of 56 x 36 cm or 56 x 38 cm, but there are exceptions. Measure your cabinet before ordering, and allow for the ventilation space the manufacturer prescribes. Freestanding models are with the microwaves.

Built-in microwaves: what to look for
A built-in microwave is chosen differently from a freestanding one. Power and capacity are comparable; the difference lies in the recess dimensions, how the appliance is ventilated, and the finish of the trim.
Which recess size?
Most built-in microwaves are made for a standard 60 cm wide kitchen cabinet, with a recess 56 cm wide and 36 to 38 cm high. Always check the stated built-in dimensions on the product itself, and leave the ventilation space the manufacturer prescribes, usually a few centimetres at the back.
How many litres do you need?
Twenty litres is enough to heat plates and mugs. From 23 litres a larger dish fits, and at 28 litres or more you can also get an oven dish in. The external size barely changes; the gain is in the shape of the interior and the diameter of the turntable.
Grill or microwave only?
A grill makes crusts: useful for toasties, gratins, or a piece of meat that needs colour. If you want to bake in it properly, look at a combination microwave with fan heat. Without a grill it stays reheating and defrosting, and for many households that is exactly enough.
Will it match my oven?
Above or below a built-in oven, a microwave only looks right if the width and finish match. Our built-in models are 60 cm wide, in black or stainless steel. Also see the built-in ovens if you are replacing both at once.
FAQ
Frequently asked questions about built-in microwaves
Cannot find your question here? Feel free to get in touch with us.
What recess size does a built-in microwave need?
Most models fit a standard 60 cm wide cabinet, with a recess of about 56 cm wide and 36 to 38 cm high. The exact built-in dimensions are listed in the specifications of each product. Also allow for the ventilation space the manufacturer prescribes, otherwise the appliance cannot get rid of its heat.
How many litres do I need?
For heating plates and mugs, 20 litres is enough. From 23 litres a larger dish fits, and at 28 litres or more you can get an oven dish in. The external size barely differs, so if your cabinet allows it, a larger capacity gives you more usable room.
What is the difference with a combination microwave?
An ordinary built-in microwave reheats and defrosts, possibly with a grill for crusts. A combination model also has fan heat, which lets you genuinely bake in it. That makes it more expensive and more complex; if you already have an oven, an ordinary microwave is usually enough.
Can I build in a freestanding microwave?
No. A freestanding model gets rid of its heat through the sides and the back, and that space does not exist inside a cabinet. Building it in leads to overheating and voids the warranty. Choose a model intended for building in, or stand a freestanding microwave freely on the worktop.
