They use standard slab sizes (e.g., 30&#215;80) but require a rough opening that is&nbsp;<strong>double the width + 1 inch<\/strong>.<\/li>\n\n\n\n<li><strong>Barn Doors:<\/strong>&nbsp;Slide&nbsp;<em>over<\/em>&nbsp;the wall. The door slab should be&nbsp;<strong>wider<\/strong>&nbsp;than the opening (e.g., use a 34&#8243; door for a 30&#8243; opening) to block light gaps and ensure privacy.<\/li>\n\n\n\n<li><strong>French Doors:<\/strong>&nbsp;Two doors side-by-side.
