Integrated Fridge Freezers
Shop integrated fridge freezers designed to fit inside kitchen cabinetry behind a furniture door. Compare cabinet niche dimensions, fridge-to-freezer split, usable capacity, fixed or sliding hinge systems, frost management, energy rating and noise level before choosing a model for your fitted kitchen.
Choosing an Integrated Fridge Freezer
An integrated fridge freezer combines chilled and frozen food storage in one built-in appliance. Unlike a freestanding model, it is installed inside a kitchen housing and concealed behind matching furniture doors.
Installation compatibility is therefore just as important as capacity and cooling features. Before ordering, check the required cabinet niche, appliance dimensions, furniture-door fitting and permitted door-front weights specified by the manufacturer.
Measure the Cabinet Niche
Measure the available cabinet opening rather than relying only on the stated appliance height. The installation specification normally gives minimum and maximum niche height, width and depth, and these measurements determine whether the appliance will fit correctly and receive the required ventilation.
Many conventional integrated fridge freezers are designed for a niche around 178 cm high, while taller models may require a cabinet around 189 cm or 194 cm. Wider integrated French-door appliances have substantially different cabinet requirements and should be assessed using the manufacturer's installation drawings.
Fixed Hinge or Sliding Hinge?
The furniture-door fitting must be compatible with the kitchen cabinet. A fixed hinge, also described as door-on-door, attaches the kitchen furniture front directly to the appliance door. A sliding-hinge system uses separate cabinet and appliance hinges connected by sliding fittings.
Do not assume that two fridge freezers designed for the same niche use the same system. For example, the Bosch KIN86NSE0G and selected current AEG integrated models use sliding fittings, while models such as the Miele KFN 7744 C use a fixed-door system.
| Furniture-door system | How it works | What to check |
|---|---|---|
| Fixed hinge / door-on-door | The furniture front is attached directly to the appliance door | Door-front dimensions, permitted weight and hinge position |
| Sliding hinge | The cabinet door and appliance door use separate hinges connected by sliding rails | Existing cabinet hinge arrangement and compatible installation kit |
Choose the Right Fridge-to-Freezer Split
A 70/30 integrated fridge freezer provides more refrigerated space, while a 50/50 layout offers a more even balance between chilled and frozen storage. Other arrangements are also available, so compare the actual fridge and freezer capacities in litres rather than relying solely on the advertised ratio.
Consider how you shop and store food. Households that mainly buy fresh ingredients may benefit from additional fridge capacity, while regular batch cooking or frozen-food storage can make a larger freezer section more useful.
178cm, 189cm and Taller Integrated Models
Integrated fridge freezers are available for different cabinet heights. Approximately 178 cm remains a common format, but taller appliances can provide additional refrigerator capacity where the kitchen furniture has been designed for them.
Do not replace a 178 cm appliance with a taller model without checking the housing. Nominal appliance height and required installation niche are separate specifications.
Standard Width or Large Integrated Fridge Freezer?
Most traditional integrated fridge freezers are designed for a standard-width kitchen housing. Larger premium models can be considerably wider and may use French-door layouts or panel-ready fronts rather than a conventional tall cabinet.
For example, selected Fisher & Paykel integrated French-door refrigerator freezers are approximately 80 cm or 90 cm wide and are designed to sit flush with cabinetry. These require different kitchen planning from a standard-width integrated appliance.
Frost Free and Reduced-Frost Integrated Fridge Freezers
Frost-management technology varies between models. A Frost Free or NoFrost freezer automatically controls ice build-up so routine manual defrosting is not normally required.
Low Frost, SmartFrost and similar systems reduce frost formation but can still require occasional manual defrosting. Check the individual freezer specification if avoiding manual defrosting is important.
Some manufacturers combine frost-free operation with separate cooling systems. AEG TwinTech No Frost, for example, uses separate fridge and freezer cooling so the freezer remains frost-free while humidity is retained in the refrigerator. Liebherr offers separate NoFrost and SmartFrost configurations across its integrated fridge-freezer range.
Fresh-Food Storage
Integrated fridge freezers can include different storage zones for fruit, vegetables, meat and dairy products. These may use humidity control, lower temperatures or separate air circulation depending on the appliance.
Selected Miele models use systems such as PerfectFresh Pro, AEG offers GreenZone and ExtraChill storage on different models, and Liebherr uses EasyFresh or BioFresh on selected integrated fridge freezers. These systems have different purposes, so compare the individual model specification rather than treating them as equivalent.
Energy Consumption and Noise
Compare the A–G energy class alongside annual electricity consumption. Capacity affects energy demand, so comparisons are most useful between fridge freezers of a similar size and storage volume.
Noise is also worth checking where the kitchen is open to a living or dining area. Compare the manufacturer's published airborne noise emission in dB rather than relying on descriptions such as quiet or silent.
Ice Makers and Water Connections
Selected larger integrated fridge freezers include automatic ice makers or ice-and-water systems. Some require a mains-water connection, while others do not.
Check plumbing requirements carefully before ordering. On panel-ready appliances, the type of door front selected can also affect whether particular dispenser functions remain available.
Integrated Fridge Freezer Installation Checklist
- Measure the cabinet niche height, width and depth.
- Confirm that the model is designed for that exact niche range.
- Identify whether the kitchen uses a fixed or sliding furniture-door fitting.
- Check the permitted furniture-door dimensions and weight.
- Confirm the appliance door hinge position and whether it is reversible.
- Allow the ventilation space specified by the manufacturer.
- Check the fridge and freezer capacities and storage split.
- Confirm whether the freezer is Frost Free, reduced-frost or manually defrosted.
- Check plumbing requirements where an ice maker or water dispenser is included.
- For wider integrated models, check the installation opening and delivery route as well as the appliance dimensions.
Frequently Asked Questions
What is an integrated fridge freezer?
An integrated fridge freezer is installed inside kitchen cabinetry and concealed behind one or more furniture doors. It combines refrigerated and frozen-food storage in a single built-in appliance.
Are integrated fridge freezers a standard size?
No. Many conventional models fit a cabinet niche around 178 cm high, but other heights and wider integrated formats are available. Always check the manufacturer's stated niche height, width and depth rather than assuming two appliances are interchangeable.
What is the difference between a fixed hinge and sliding hinge?
A fixed or door-on-door system attaches the kitchen furniture front directly to the appliance door. A sliding-hinge system uses separate cabinet and appliance hinges connected by sliding fittings. Replacement appliances need to be compatible with the intended cabinet installation.
Can I replace a sliding-hinge fridge freezer with a fixed-hinge model?
It may be possible if the kitchen furniture and cabinet are altered appropriately, but the systems are not direct like-for-like replacements. Check the appliance installation instructions and cabinet construction before ordering.
What does 50/50 or 70/30 mean on an integrated fridge freezer?
The ratio describes the approximate balance between refrigerator and freezer storage. A 70/30 model prioritises chilled capacity, while a 50/50 model offers a more even split. Compare the stated capacities in litres for a more precise comparison.
Do integrated fridge freezers come in Frost Free models?
Yes. Many integrated fridge freezers use Frost Free or NoFrost freezer systems, while others use reduced-frost technology. Check the individual product specification because these systems are not equivalent.
What should I measure before buying an integrated fridge freezer?
Measure the kitchen cabinet niche height, width and depth. Also identify the furniture-door fitting, check the permitted door-front weight and confirm the manufacturer's ventilation requirements.
Can you get large integrated French-door fridge freezers?
Yes. Selected premium integrated ranges use wider French-door or bottom-freezer formats designed to sit flush with kitchen cabinetry. They need significantly different cabinet planning from a conventional standard-width integrated fridge freezer.
