When designing a sliding barn door, the chosen door or doors must not be too heavy for the track system they use. Before drilling, double check the frames of older homes, especially the ones built without a permit. A stud finder is not enough for the job. Cut a 2-inch-by-2-inch square out of the wall 6 inches above the door, and ensure that the beam can be seen.
At every interval where the barn door track will be attached, which includes the extension beyond the door opening, a stud or a wooden block should be installed under the drywall to provide ample support. Wood blocking is preferred over drywall anchors. Ensure that the city where the barn door is installed does not require a permit. In some cities, a permit is necessary for any home improvement that costs more than $500.
Since a barn door does not lie even with the door opening, it leaves a gap between itself and the drywall. Therefore, when installing barn doors for bathrooms, ensure the best possible contact between the door frame and the door. Choose carefully if the rollers should be on the interior or the exterior of the door, since this affects the overlap between the doors and the walls when closed. Finally, choose a barn door material that harmonizes with the house and adds to the overall appeal.
