Sliding mirrored doors increases the space in a room, and masking a floor-to-ceiling wardrobe will create a visually much larger room. If you have decided to redecorate the room and the style no longer matches what you want to do, you have to opt for other doors. The compartmentation may remain the same, and the doors may change to match the new style adopted. If mounted on an exterior wall, moisture can be a problem for built-in furniture. Most custom cabinets are mounted without the back panel to help reduce this problem.
