Mud-in vents and lights are becoming more popular on super luxury homes, especially for large feature walls. These vents are installed flush into the drywall, creating a seamless and modern look. They can be painted or covered with wallpaper to match the walls. While they can be DIYed, it's recommended to consult with a drywall contractor for pricing and installation. These vents are great for adding a touch of modern luxury to any space, especially in areas with dark colors or feature walls. Consider incorporating them for a sleek and upscale finish.
