What is the difference betwen a "built-in appliance" and a "built-under appliance". Can either be hidden behind a door to match thr rest of the kitchen.
Your built in appliance will have the door attached to it with brackets.
Your built under will not and will be visible when you walk into the kitchen.
If your worktop is deep enough, there's nothing to stop you slotting the appliance under and attaching a cupboard door like you in the rest of the kitchen without attaching it to the actual appliance.
