The only downside to sliding closet doors is the maintenance, which is required to make sure they will run perfectly along the track. You should regularly check the track as well as the casters to make sure they are in good working order.
If you have a limited amount of closet space and you do not have a closet already installed in your home, there are prefab wardrobe closets, which you can place in your room in order to hang your clothing. These come in many different styles, from being made of particle board to real wood with various types of finishes. In fact, wardrobe closets are very popular for those who live in apartments and cannot build a closet or add closet space to their home. This is because the wood finish many of these closets are made from can be designed to match any decor you already have in your home, without looking as though it is out of place.
These wardrobe closets come in many different sizes as well, from double-door closets to single door closets, which offer hanging space for clothing, and shelving space for shoes or other pieces of clothing. No matter what your closet solution is, sliding closet doors can make a great way to conserve space, and if you just do not have enough closet space at all, you could purchase a wardrobe closet in order to hang all of your clothing.
These solutions are all viable options for people who live in a small space and want to make the most of the space they have without adding additional spaces, or for people who cannot build their own closet additions.
