Imagine having built-in wardrobes with regular doors. You need to have enough space to open them any time you need to get something from inside the cabinet. That means you need to make sure that nothing is blocking the door, and that you might lose some valuable free space. Sliding doors have a very simple mechanism, are very easy to use, and the fact that they look also nice, makes them the perfect fit for any type of cabinet. Just go to a furniture store, see what they recommend, and go for it.
