What is the difference between freestanding, integrated and built-under appliances?
They describe how an appliance fits into the kitchen, and the choice affects cost, flexibility and what happens when it breaks.
Freestanding. A finished appliance on all visible sides, designed to stand alone in a gap. It has its own finished top, sides and control panel.
Advantages: cheapest; widest choice of models; easy to install and to replace; takes it with you when you move; and simple to pull out for repair or cleaning behind.
Disadvantages: visible as an appliance, gaps at the sides collecting dirt, and a less seamless kitchen.
Integrated (built-in). Designed to be installed within cabinetry, usually with a decor panel matching the kitchen doors fixed to the front so it disappears entirely. Fridges, freezers, dishwashers and washing machines are all available integrated.
Advantages: a seamless, uniform kitchen, and appliances hidden completely.
Disadvantages, which are frequently underestimated:
Cost is higher, for both the appliance and the door furniture and fitting.
Capacity is smaller for the same external space, because the appliance sits inside a housing. Integrated fridges in particular hold noticeably less than a freestanding equivalent of the same width.
Replacement is constrained. You must find a model matching the housing dimensions and door-fixing system, and standards vary between manufacturers. A discontinued size can mean altering the kitchen.
Repair access is more awkward.
Ventilation matters — integrated fridges and ovens need the housing's specified gaps kept clear.
Built-under. Sits beneath a worktop but is visible at the front, with its own finished fascia rather than a matching door. Common for ovens under a hob, and for dishwashers and washing machines where a worktop runs over them but no door panel is fitted.
It is a middle option — a continuous worktop line without the cost and constraints of full integration. Check height carefully, since built-under models are often slightly shorter.
Slot-in and semi-integrated variants also exist, particularly for dishwashers with a visible control strip.
