An integrated model is designed to be incorporated into cabinetry with the intended fittings. A freestanding washing machine that fits under a countertop does not therefore gain the requirements or accessories of an integrated model.
What each installation type means
Freestanding describes an appliance with a casing designed to be visible. Under-counter indicates an installation position that must be permitted. Integrated implies provisions for joining with cabinetry, such as door hinges and built-in dimensions. In some markets, built-in is used less precisely: you need to read the manufacturer’s drawing.
Why width is not enough
The opening must let you close the cabinet without pressing controls, open the door and detergent drawer, route hoses without bending them, and remove the appliance for service. It also needs to meet the documented clearances and ventilation requirements. A cabinet front can change the opening path and access to the lower section.
Removing the top from a freestanding machine is only permissible if there is a procedure and, where applicable, an approved cover or kit. The top may be part of the appliance’s protection: reducing the height by removing it is not an automatic solution.
Washer-dryers and rear access
In a built-in washer-dryer, the thermal operation adds its own requirements; the cabinet should not be designed by copying the requirements of a washer-only machine without checking them. Before adjusting hinges or panels, gather the appliance and operating-space dimensions.
The guide to installation inside cabinetry helps organize the physical checks. Here the main distinction is documentary: the manufacturer must provide for the chosen installation type.
Request the installation drawing for the exact variant, not just the dimensions from a sales sheet.
