However, for every drawback, there is an advantage. Below are a few drawbacks, but we couldn't just give you the drawbacks without the benefits so we have included a few of those as well...

Drawbacks

• They cost more than a regular door (but this is an obvious one, there are a lot more parts, the door is on runners, the kit makes up part of your wall)
• On the subject of more parts, yes, this means there are more things that could go wrong if installed incorrectly or if abused by a overzealous user
• The pocket section of the kit is not a solid wall so will naturally allow more sound to pass through and will be more flexible than a solid wall
• If they DO break, typically it would require destructive access to repair. However this depends on what has happened. Some faults can be fixed without bashing holes in your wall
• Raked heads on pocket doors are not a thing. A point to consider if you pocket door is going into an attic (depending on its orientation to the sloping ceiling)

Benefits

• You save floor space
• They provide an impressive feature
• You can close off spaces without the need of bifold or swinging doors
• For infrequently used doors, they can slide away out of sight and not get in anyone's way
• Great option for use in narrow corridors or for going into small rooms
• Gives you more useable space in a room as you do not have to allow for space for the door to swing
