Are the front and back of custom wardrobes the same?

Not necessarily the same, it depends on personal preference.

It is okay to have a wardrobe with front and back openings. But there is a premise: the wardrobe cannot be placed against the wall, so there is no point in opening it from both sides. Wardrobes that open on both sides are mainly used in larger rooms. When using the wardrobe as a partition, it is very convenient to open the doors on both sides, especially if one side is the bedroom and the other side is the cloakroom. This design can be adopted with doors opening on both sides. Some hotels also use wardrobes that open on two sides, with one side for the bedroom and the other for the bathroom drying area (changing area). The design is very humane.
