The unit that most commonly requires wallcovering in residential and commercial settings is the bedroom. Wallcovering is often used in bedrooms for aesthetic reasons, as it can add texture, color, and pattern to the space, creating a cozy and personalized environment. According to the National Retail Federation, the wallcovering market in the United States has seen steady growth, with consumers increasingly seeking ways to enhance the look and feel of their living spaces. Wallcovering can also serve practical purposes, such as protecting walls from moisture and stains, which is particularly important in bedrooms where there may be more humidity due to activities like showering or breathing. Additionally, wallcovering can be a cost-effective alternative to painting, as it can be more durable and easier to maintain.
