Glass shower door installation is usually a one-person job, according to This Old House. Most homeowners can install a framed glass shower door in two to four hours, but unframed glass shower enclosures are more difficult and time consuming to install.
The tools required to install a glass shower door include a level, a caulk gun, a drill, a hacksaw and a utility knife. This project also requires a plastic mallet, a 10-inch file, a tape measure, screwdrivers and a shop vacuum. Canvas drop cloths prevent damage to surrounding surfaces, and isopropyl alcohol prepares the walls and door threshold for caulk application.
