Your new dishwasher can look perfectly at home behind a matching kitchen door, but integrated appliance installation only works well when the appliance, cabinet and door are specified together. A few millimetres, the wrong hinge system or insufficient ventilation can turn a great-value purchase into an expensive delay.
For anyone replacing a failed built-in appliance, renovating a kitchen or fitting out a rental property, the best time to check installation details is before ordering. It protects your budget, helps delivery day run smoothly and gives your installer the information they need.
What does integrated appliance installation involve?
An integrated appliance is designed to sit inside a kitchen housing unit and be covered by a furniture door that matches the rest of the kitchen. Common options include integrated dishwashers, washing machines, washer dryers, fridge freezers and under-counter fridges.
The appliance itself is not usually supplied with the cabinet or matching furniture door. Those parts come from your kitchen, so the appliance must suit the opening, door height and hinge arrangement already in place. This is why an integrated model is not simply a freestanding appliance with a door fitted in front.
Built-in and integrated are often used interchangeably, but there is a useful distinction. A built-in oven or microwave sits within cabinetry but its front remains visible. An integrated dishwasher or fridge freezer is concealed behind a cabinet door. Check the product description carefully, particularly if you are replacing like for like.
Measure the space, not the old appliance
It is tempting to measure the appliance being removed and buy the closest match. Kitchen units can vary, however, and an older appliance may have been adjusted to fit. Measure the cabinet opening itself: its height, width and depth, plus the space behind it for pipes, plugs, ventilation and door movement.
Most full-size integrated dishwashers are designed for a 60cm-wide housing, while slimline models fit a 45cm-wide space. That sounds straightforward, but width alone is not enough. The appliance feet need room for levelling, and the door must clear the plinth when it opens.
For integrated washing machines and washer dryers, check the worktop height and the available depth particularly carefully. Hoses and connections take up room at the rear. Pushing an appliance too far back can pinch a hose, strain a cable or prevent the furniture door from lining up correctly.
Fridge freezers need even more attention to the housing dimensions. A tall integrated fridge freezer may look similar to another model from the front while differing in niche height, split-door layout or required ventilation. Always compare the manufacturer's installation drawing with the actual cupboard, rather than relying on a previous model number.
Measure the route into your home as well
A correctly sized appliance still has to get to the kitchen. Check doorways, narrow hallways, stairs and turns in advance, especially for tall fridge freezers. If you are arranging nationwide two-person delivery, tell the retailer about any access concerns before delivery is booked. Optional unpacking can make it easier to inspect the appliance and move packaging out of the way, but it does not replace professional fitting where connections or cabinetry need work.
The furniture door and hinge system matter
The furniture door is one of the most commonly missed parts of an integrated appliance installation. Your existing door needs to be compatible with the appliance's fitting method, its height and its weight limits.
There are two main arrangements. A fixed-hinge system attaches the kitchen door directly to the appliance door, so both move together. A sliding-hinge or door-on-door runner system allows the furniture door and appliance door to move slightly independently. They are not automatically interchangeable.
If you are replacing an older integrated dishwasher, washing machine or fridge, find out which system your kitchen uses before choosing a model. You may be able to change the fitting arrangement, but it can involve new drilling, different brackets or a replacement door. That may be worthwhile during a full kitchen refresh, but it is rarely the simplest option for an urgent replacement.
Door height is equally important. Some integrated dishwashers offer a variable hinge or sliding mechanism to suit taller doors and lower plinths. Others have more limited adjustment. For a tidy finish, share the door measurement and plinth height with your installer or ask a knowledgeable sales team to help check the specification before you buy.
Plan connections before delivery day
Integrated appliances need the same services as comparable freestanding models, but access is more restricted once they are in place. Confirm where the sockets, isolation valves, waste pipe and water supply sit before fitting begins.
A dishwasher requires a cold-water feed, waste connection and suitable electrical supply. A washing machine or washer dryer needs similar connections, with enough hose length to reach without stretching or kinking. Do not use an extension lead hidden behind an appliance. Sockets should remain safely accessible as required by the appliance instructions and current electrical guidance.
For an integrated fridge or freezer, electrical supply and ventilation are the priority. Heat must be able to escape through the ventilation route specified for that model, which may involve vents at the base, top or rear of the housing. Blocking those gaps can reduce efficiency, increase running costs and shorten the life of the appliance.
If your project includes a gas hob, gas cooker or gas connection, use a Gas Safe registered engineer. Electrical alterations, new circuits and plumbing changes should also be carried out by an appropriately qualified professional. Saving money on the appliance should not mean cutting corners on safety.
Allow for ventilation, levelling and access
Integrated appliances are designed to disappear visually, not to be sealed into a box. The installation manual will state the required clearances and ventilation. These measurements are model-specific, so do not assume that a gap suitable for your old fridge freezer will suit a new one.
Levelling is another practical detail that affects everyday use. A dishwasher that is not level may not drain as intended, while a fridge freezer can have doors that fail to close properly. The adjustable feet should be set before the appliance is secured and the furniture door is finally aligned.
Keep the appliance manual, model number and proof of purchase somewhere accessible after fitting. If service is needed later, this makes it much easier to identify the correct spare part or explain the setup to an engineer.
Replacing an appliance versus fitting a new kitchen
A like-for-like replacement is usually the quickest route, provided the new model matches the cabinet size, door system and required connections. Take photographs of the current installation before it is removed, including the hinges, plinth, pipework and appliance label. They can answer questions that become harder once the old machine has gone.
A new kitchen gives you more flexibility, but it also means more decisions. Choose appliances early enough for the kitchen designer or fitter to build the correct housing, ventilation and service positions around them. Waiting until the cabinets are installed can limit your choice or lead to extra alteration costs.
For landlords and homeowners managing a strict budget, graded, ex-display or liquidation appliances can offer strong savings. Check the product condition, included fittings and warranty details, then confirm that the exact model works with your kitchen measurements. A discounted appliance is only good value if it can be fitted correctly.
Questions to ask before you order
Before committing, have the product dimensions and installation drawing to hand. Confirm whether the model is fully integrated, whether it needs a fixed or sliding furniture door, and whether the required door panel and fittings are included or supplied separately.
It is also worth asking about the appliance's ventilation requirements, the position of the mains lead and hoses, and whether the stated depth includes connections. If you are unsure, send measurements and photos to the sales team. HomeWise Appliances can help shoppers compare formats and avoid choosing a model that looks right online but does not suit the kitchen at home.
A careful check now is usually cheaper than a second delivery, a replacement cabinet door or an unexpected visit from an installer. Choose the appliance that fits your space as well as your budget, and fitting day can be the satisfying final step rather than the start of a problem.
