The term "standard built-in cabinet with sliding door" implies a custom-made built-in cabinet, going from floor to ceiling (height), from wall to wall of the room (width), or from the room wall to the end wall in free space.
A built-in cabinet should be fully custom-made, tailored according to you and your needs and habits, your space and taste. It should be unique, yours only. Additionally, of course, it should be of high quality, functional, durable and reliable.
