Type of closet is a term used to describe the various types of storage spaces used in homes and other buildings. The three most common types of closets are LINEN, CEDAR, and walk-in. A LINEN closet is typically a shallow cupboard or cabinet used to store items such as towels, sheets, and other bedding. CEDAR closets are usually made of CEDAR wood and are used to store clothing and other items that need to be kept in a dry, insect-free environment. Walk-in closets are larger than the other two types and are often used to store clothing and other items that require more space.
