How to Enclose a Shower

Measure the width of the shower entrance at the bottom of the opening. Measure the width 5 feet above this point. Measure halfway between the two points. Check the walls of the opening for plumb. Give all of the measurements to your distributor and wait for your doors.

Cut the base track, the grooved metal the door will fit into, to the length of the opening with a hacksaw. Center the track on the shower threshold. Draw a line on the threshold on each side of the track. Remove the track. Apply caulking adhesive between the lines. Set the track in place again and press down. Allow the adhesive to dry.

Fit a jamb into the track on the threshold. Mark the screw holes in the jamb on the tile. Take the jamb out of the base track. Drill holes in the tile at the marks on the wall. Use a 3/16-inch masonry bit.

Set plastic anchors into the screw holes. Replace the jamb so that its holes align with the holes on the wall. Check for plumb with a carpenter's level. Fasten the jamb to the wall with panhead screws.

Install the jamb on the opposite side of the wall the same way you did the first one.

Measure between the tops of the two jambs. Cut the top track, the metal piece that the tops of the doors will fit into, to the measured length. Apply caulk to the end of the top track where it meets the jambs. Press the track firmly against the jambs for a tight bond.

Fasten the door handle or handles, if they do not com preinstalled. Thread the screws into the handle's predrilled holes. Place a washer and nut on the back of each screw. Hold them in place with pliers as you tighten the screws.

Set a door into position by sliding its rollers into a groove at the top track. Fit the bottom rollers into the corresponding bottom groove. Install the remaining door into the other grooves in the tracks.
