Pocket Door Guide: Planning, Kits and When to Use One

Pocket doors are brilliant where a swinging door steals useful space, but they need more planning than a normal hinged door. The wall has to accept a cassette, the track must be level, and the finished opening needs to stay serviceable.

Safety noteDo not cut into a wall until you have checked for cables, pipes, structural supports and any fire or acoustic requirements. Pocket doors are often best planned with a carpenter or builder, especially on structural, fire-rated, tiled or service-heavy walls.

1. Choose the right wall before buying the kit

Measure the door opening, the full pocket length and the wall thickness. A pocket door needs somewhere for the slab to disappear, so check both sides of the wall for switches, sockets, radiators, pipework, shelving and fitted furniture.

  • Confirm the required finished opening, not just the existing door size.
  • Check the kit thickness against the wall build-up and plasterboard finish.
  • Use a detector and visual inspection before deciding the wall is suitable.
  • Plan handles, privacy locks and soft-close hardware early because they affect the kit choice.

2. Open the wall and set the cassette square

Follow the kit instructions closely. The cassette and head track need to be level, plumb and fixed firmly, because small errors become obvious when the door slides. Pack the frame where needed and protect the track from dust while you work.

  • Keep the head track perfectly level before tightening final fixings.
  • Use packers so the frame is supported rather than pulled out of shape.
  • Check floor level and finished floor height before setting the bottom guide.
  • Keep plasterboard screws away from the pocket cavity so they cannot scratch the door.

3. Test the door before closing the wall

Hang the slab, adjust the rollers and test the slide while you still have access to the cassette. The door should move smoothly, meet the jamb evenly and stay controlled through the full travel.

  • Adjust height and gap evenly at both sides.
  • Test soft-close, stops and pull hardware before boarding over the frame.
  • Make sure the door cannot rub the cassette, floor guide or plasterboard screws.
  • Only close the wall once the movement feels right several times in a row.

4. Board, trim and make it look intentional

Once the mechanism is proven, close the wall, tape and skim or finish the plasterboard, then fit architrave and stops. Pocket doors look best when the trim lines are clean and the handle hardware is easy to grip without fighting the door.

Good pocket door uses

  • Small bathrooms and ensuites
  • Utility cupboards
  • Wardrobes and dressing areas
  • Tight hallways where a hinged door blocks the route

Think twice if

  • The wall carries services you cannot reroute safely
  • The wall may be structural or fire-rated
  • You need strong acoustic separation
  • You cannot access the track for future adjustment
