Integrated Washing Machine. The idea with the integrated washing machine is that a cupboard door is fitted in front of the machine. This gives it an “inbuilt” look, like it has been built into the room where it is installed.Often, it is installed in the kitchen and not in other places as the kitchen units provide stability to the machine, and it blends with the decor. It is a good design for small spaces, hotel rooms, offices and even homes.
