I would like door ideas, or alternatives, for a downstairs den area. There is a full bath right next to the den (see doorway on the left), and we would love to add a door to the den to use it as a downstairs guest room. The doorway is 36" wide and 97" tall. We don't have space for a barn door, but I'm open to other types of doors. Or should we just install a regular door there? I have no idea what to do!
