Common Pocket Door Questions
Installation & Placement
Can you put a pocket door on a block wall?
Yes. You can either:
-
Use a pocket door kit designed for a 6" wall, or
-
Fur out a standard 2x6 kit by 1/2"
For existing block walls, the easiest option is to build an add-on wall rather than tearing into the block.
Where can you not put a pocket door?
Pocket doors can go almost anywhere, except typically:
-
Load-bearing walls (unless a structural beam is added, which is costly)
Alternative:
-
Build an additional wall in front of the load-bearing wall
They are mainly used in interior walls.
Can I install a pocket door without removing drywall?
-
Existing wall: You must remove drywall in the installation area
-
New wall: Frame the opening first, then add drywall
Door Compatibility
Can any slab door be used for a pocket door?
Yes. Options include:
-
Hollow core
-
Solid core
-
Wood panel (raised or flat)
-
French doors with glass
You can even reuse doors with:
-
Hinge cutouts (place that side inside the wall)
-
Standard 2 1/8" lock bores (use compatible pocket door locks)
Sizing & Framing
How thick are standard walls for pocket doors?
-
2x4 wall: 3 1/2"
-
2x6 wall: 5 1/2"
-
Block wall: ~6"
Drywall (applied both sides):

Custom wall thickness kits are also available.
What size opening do I need?

Width: (Door width × 2) + 1"
-
Height: Door height + 4 1/2"

80" door → 84 1/2" rough opening height
Double doors:

Opening = 4× width of one door
