That said if you choose a regular door handle to slide the door open and shut, then this will be your stopping point and the door will protrude slightly from the wall. That’s why more common is a fingertip closer which consists of a metal plate on each face of the door.
Encased in a standard (timber or metal) stud wall, the mechanism is straightforward: a metal formwork with a rail. The cost is also reasonable, with the sliding mechanism for a standard sized door in the region of €100/£90. Doors off the shelf can cost anywhere from €20/£18 to €200/£180, or you could repurpose a door you already have.
