Pocket doors slide into the wall instead of swinging into the room, reclaiming 10 to 14 square feet of floor space that a hinged door consumes. Learning how to install a pocket door is an intermediate-level project that takes a full weekend and costs $200 to $600 in materials, compared to $400 to $1,200 for professional installation. The process involves removing a section of wall, building a specialized frame, hanging the door on a rolling track, and finishing with drywall and trim.
Tools and Materials List
A pocket door kit includes the split-stud frame, overhead track, rollers, and door guides. Johnson Hardware and Sterling by Kohler make the most widely available kits at $50 to $150 for standard 30-inch and 36-inch door widths. You will also need the door slab itself, which is sold separately. A hollow-core slab costs $40 to $80, while solid-core runs $100 to $250.
- Pocket door frame kit sized to your door width ($50 to $150)
- Door slab: 1-3/8 inch thick, sized to match the frame kit
- Drywall: Two sheets of 1/2-inch for each side of the pocket wall
- Trim and casing: Enough to frame both sides of the opening
- Tools: Reciprocating saw, level, drill, framing square, drywall tools, stud finder
- Fasteners: 3-inch screws for framing, drywall screws, finish nails
Planning and Measuring
The wall that receives the pocket must be at least twice as wide as the door, plus 3 to 5 inches for the jamb and hardware. A 30-inch door needs approximately 65 inches of wall space. A 36-inch door needs about 77 inches. Verify that no electrical wiring, plumbing, HVAC ducts, or structural elements run through the wall section where the pocket will go. Use a stud finder and, if needed, cut a small inspection hole to look inside the wall cavity before committing.
Load-bearing walls require a properly sized header above the opening to transfer the load around the pocket. A 36-inch opening in a load-bearing wall needs a doubled 2×8 or 2×10 header depending on the span and loads above. Consult a structural engineer or experienced contractor before modifying any load-bearing wall. Non-load-bearing partition walls need only a standard 2×4 header.
Removing the Existing Wall Section
Turn off electrical circuits for any wiring in the wall. Remove baseboard trim and save it for reinstallation. Score the drywall along the edges of the area you need to open, then cut with a reciprocating saw or drywall saw. Remove drywall on both sides of the wall to expose the full pocket area plus the door opening.
Cut out existing studs with a reciprocating saw, leaving the bottom plate and top plate intact. If you encounter wiring, reroute it around the pocket area before proceeding. Plumbing and HVAC ducts cannot be easily rerouted, which is why wall inspection during planning is critical. A surprise pipe inside the wall can turn a weekend project into a multi-week renovation.
Building the Pocket Frame
Assemble the pocket door frame kit on the floor following the manufacturer’s instructions. The frame consists of split studs (thin metal or wood channels that allow the door to slide between them) and an overhead track that supports the door weight. Level is absolutely critical during this step. Even 1/8-inch deviation causes the door to roll to one side or rub against the split studs.
Stand the assembled frame in the wall opening and secure it to the top plate and bottom plate with 3-inch screws. Plumb both sides of the frame with a 4-foot level, shimming as needed. The overhead track must be perfectly level so the door rolls smoothly without gravity pulling it in one direction. Secure the track to the header with the provided hardware, checking level at three points along the rail.
Hanging the Door
Attach the roller hardware to the top edge of the door slab. Most kits use two adjustable hangers with nylon wheels that ride in the overhead track. Lift the door into the track by tipping it into the opening and engaging the rollers one at a time. This step is easier with two people since even a hollow-core door becomes awkward to maneuver into an overhead track solo.
Adjust the roller height so the door hangs 1/2 inch above the finished floor. Turn the adjustment screws on each hanger to raise or lower each side independently. The door should hang plumb with equal gaps on both sides. Install the floor guide at the bottom of the door opening, centering it so the door slides into the pocket without rubbing the split studs or swinging side to side.
Finishing with Drywall and Trim
Apply 1/2-inch drywall over the split studs on both sides of the pocket wall. Use short drywall screws (1-inch or 1-1/4 inch) to avoid puncturing through the split studs and scratching the door face inside the pocket. Standard 1-5/8 inch drywall screws are too long and will damage the door. Mark the stud locations before hanging drywall so you know exactly where to place screws.
Tape, mud, and sand the drywall joints as you would any wall. Install door casing trim around the opening on both sides. A pocket door uses a split jamb system where the strike-side jamb doubles as the door stop. Install the provided edge pull hardware on the door face so you can grip the door when it is fully recessed. Passage-style pocket door locks ($15 to $40) replace standard doorknobs and use a hook mechanism that engages the strike plate in the jamb.
Common Installation Mistakes
The number one mistake is an out-of-level track. Check level repeatedly during frame installation. An out-of-level track causes the door to drift open or closed on its own, and the only fix is disassembling the drywall and readjusting the frame. Using drywall screws that are too long ranks second. Screws that penetrate the pocket chamber scratch the door every time it slides, eventually gouging the finish and causing the door to bind.
Skipping the wall inspection leads to the most costly surprises. Cutting into a wall and discovering a drain pipe or HVAC duct means either relocating those utilities or abandoning the pocket door location entirely. Spend 30 minutes with a stud finder and inspection camera before picking up a saw. The third common error is choosing a warped door slab. Sight down the edge of the slab at the lumber yard and reject any door that shows more than 1/8-inch bow across its length.
