To prevent sagging, consider both the material and the span of the shelf. Using sturdy materials such as plywood or solid wood can provide better support than particleboard. Additionally, limiting the shelf span to 36 inches or less can reduce the risk of sagging. For longer shelves, incorporating center supports or brackets can offer additional reinforcement.

Bedrooms and living rooms generally cost the least to remodel. Of course, the project price will depend on what you're planning to do to the space and the cost of the materials you choose to incorporate. Prices are typically lower than those of other remodels because major plumbing, electrical, and HVAC work isn't often part of remodeling these rooms.

Different types of closets are defined mostly by size. A few different types of closets include:

• A reach-in closet is a smaller closet that you can stand in front of and reach everything inside it. Aside from the size, the doors and the level of drywall finish are typically the largest price factors.  

• A walk-in closet can be anything from a small 5-by-5 feet closet that has a narrow walkway with shelves on both sides to a 100 square foot bedroom-sized closet with shelving along the walls and plenty of room to move around in.

• A built-in wardrobe often does not have a door and leaves the clothes and other contents open to the room, whereas a closet usually has a door to separate it from the rest of the room.

Although you can complete a closet frame in just an afternoon, finishing the entire closet will take a few days to a week. However, that’s still not as much as the average time it takes to remodel a closet, which can take anywhere from several weeks to more than a month. That’s because you also have to consider the time it will take to demolish the existing space, plan a new design, order materials, and actually install it.
