To replace a built-in fridge while keeping your cabinetry and cabinet door, first measure the niche and identify the existing door-fixing system, then compare them with the instructions for the model you’re considering. Sliding-door and fixed-hinge systems are not interchangeable by default: also check the ventilation requirements and get any proposed modifications approved before you buy.
If you want to keep the visible doors on your cabinetry, identify their fixing system, dimensions and movement before choosing an appliance. Bosch Home Appliances France explains the differences between sliding-door and fixed-hinge mounting.
The height, width, depth and airflow through the housing can all limit your choice of suitable models. Compare the clear internal measurements of the cabinet with the installation diagram for the exact model; Liebherr France product pages distinguish between appliance dimensions and niche dimensions, for example.
If you’re deciding between a fridge-freezer and a single-door fridge, check the usable capacity of each compartment and whether you need a freezer. UFC-Que Choisir distinguishes between several fridge formats, including single-door models and fridge-freezers.
Consider this: if the cabinet door remains hinged to the cabinet and the model’s instructions confirm this type of mounting.
Check: the rails, cabinet doors and door positions must match the appliance diagram.
Consider this: if the cabinet door is designed to be fixed directly to the appliance door.
Check: the model and its instructions must confirm the fixing system and cabinet door specifications.
Consider this: if your freezer needs are covered elsewhere and the niche is suitable for the appliance.
Bear in mind: a model without a freezer is not a like-for-like replacement for a fridge-freezer.
| What to consider | What to check before buying | Who prioritises this most |
|---|---|---|
| Niche dimensions | Measure the clear internal height, width and depth, then compare them with the installation diagram for the exact model. Don’t confuse these measurements with the appliance’s external dimensions. | I want to avoid choosing an appliance that’s too large to fit in my existing cabinetry. Around 26% of consumers are thought to prioritise finding a model that fits the niche. |
| Cabinet door fixing | Check where the hinges are fixed and which system the instructions specify: sliding-door or fixed-hinge. Also compare the cabinet doors and their drill holes. | I want to keep my cabinet doors without assuming their hinges will suit the new appliance. Around 26% of consumers are thought to prioritise the fixing system. |
| Cabinet ventilation | Locate the air inlets and outlets, plinth and rear clearance, then compare their layout with the appliance’s ventilation requirements in the instructions. | I want to keep my kitchen cabinetry without blocking the openings needed for installation. Around 21% of consumers are thought to prioritise airflow through the housing. |
| Capacity and freezing | Compare the usable fridge and freezer capacities separately, and check whether the appliance has a freezer and what type of cooling system is specified. | I want enough space for fresh and frozen food, or to choose a single-door model if I have a freezer elsewhere. Around 16% of consumers are thought to prioritise this. |
| Energy use and services | Compare the energy use in kWh/year of compatible models, and check what’s included in delivery, disconnection, installation and removal of your old appliance. | I want to plan for energy use and find out which parts of the replacement are covered. Around 11% of consumers are thought to prioritise these costs and services. |
The appliance dimensions and the dimensions of the niche it needs are not the same. Compare all three clear internal measurements of the cabinet with the installation diagram for the exact model.
A difference in dimensions could mean modifying the cabinet or arranging another installation visit.
These systems connect the cabinet door to the appliance in different ways: with sliding-door mounting, the cabinet door moves the fridge door; with fixed-hinge mounting, the cabinet door is attached to the appliance door. Identify the existing system and check the instructions before considering any conversion.
Changing the mounting system may require modifications to the cabinet door, hinges or drill holes.
The plinth and cabinet must allow for the airflow route specified for the appliance. Locate the existing openings and compare them with the model’s ventilation diagram before keeping or modifying the cabinetry.
In France, the DGCCRF reminds shoppers that retailers must take back an equivalent used appliance free of charge when they sell a new one (‘one for one’). This does not, by itself, confirm whether disconnection, removal of the cabinet door or taking the built-in appliance out of the cabinet are included. Ask for a quote that sets out each service separately.
Its resources explain sliding-door and fixed-hinge mounting, and some model pages specify the door system used.
French product pages for the models mentioned distinguish between sliding-door mounting and fixed hinges, with specific niche dimensions for each.
The KI86VVSE0 and KI86NSFE0 models illustrate two different door systems: sliding-door and fixed-hinge mounting.
The product page for the LRB3AE12S single-door fridge specifies sliding-door mounting and built-in dimensions.
The product page for the BCNA275E44SN built-in fridge-freezer specifies sliding-door mounting.
This selection includes sliding-door built-in models, a single-door fridge and a fridge-freezer, as well as a model described on its product page as having a flush-fitting design. Before choosing any model, check the niche, door fixing system and ventilation requirements in its instructions.

Worth considering if your cabinet is designed for sliding-door mounting and the niche dimensions match the instructions for this model.
The Joybuy product page lists a sliding-door fridge-freezer with a 249 L capacity and TwinTech Total No Frost technology.

Consider this if you’re looking for a single-door appliance and have your freezer needs covered elsewhere.
The Joybuy product page lists a capacity of 188 L, automatic fridge defrost and stated annual energy consumption of 101 kWh. This model is designed for fresh food storage and does not keep food frozen.

Compare this model if you’re looking for a built-in fridge-freezer with sliding-door mounting and its stated dimensions suit your cabinetry.
The Joybuy product page lists a niche size of 56 × 122,5 × 55 cm and sliding-door mounting. The freezer compartment requires manual defrosting.

Only consider this after confirming that its installation type suits your cabinetry: the product page describes it as a flush-fitting KITFIT design, but that alone does not confirm that it will fit an existing niche.
The Joybuy product page lists a height of 191 cm and a 28 L Care+ zone with three temperature settings.
Measure the clear internal height, width and depth of the niche, each cabinet door and the position of the divider between two doors. Take photos of the hinges and sliding rails, then compare everything with the installation diagram for the exact model: external dimensions alone aren’t enough.
Not without checking the system specified for the appliance and cabinet door. With sliding-door mounting, rails transfer movement between the cabinet door and the fridge door; with fixed-hinge mounting, the cabinet door is attached directly to the appliance door. Get the hinges, dimensions and drill holes checked before making any changes.
Ask for advice before buying if the niche, plinth, ventilation or existing fixings don’t match the model diagram. Bosch Home Appliances France recommends using a professional for built-in installation; Electrolux Assistance France warns that work carried out by a non-professional can have safety implications. These recommendations do not mean that professional installation is a general requirement for every fridge.
Follow the ventilation diagram in the instructions and keep the specified openings clear. Don’t automatically apply a general measurement to your appliance: follow the requirements for the exact model you’ve installed.
