Replace a closet door with a bookcase door. Great idea to hide the water heater. No more ugly, never touched water heater door.
bookcase sliding door - hides secret passageway :D
how to make a secret door a room or closet. I think we'll figure out how to do this for double doors. I have double doors between my sew/craft room and what will be the dining room. more storage in what would have been lost space .
I wonder if we could change the bifolds in the basement to the furnace to double bookshelf doors?
