Step 1: Remove the Panels

Before you can install the bottom and side jambs of the new tub and shower door, you have to remove the old shower door completely. Work slowly and carefully to prevent accidental damage to the surrounding area. Working too quickly can often make more work for everyone involved in the project.

Lift and remove the outside door panel (Image 1), then the inside one (Image 2), followed by the top track (Image 3).

Step 2: Loosen the Jambs

Lay a drop cloth in the tub and, using a screwdriver and a claw hammer, begin to pry loose the screws that fasten the side jamb to the wall (Image 1). With the screws removed, use a utility knife to make a cut on the outside of the jamb where the caulk adjoins the jamb to the wall; make the same cut for the inside of the jamb facing the shower.

Place the edge of a putty knife in the groove of the cuts and tap the knife end with a hammer to loosen the caulk (Image 2). When the bond has been broken, pull the jamb out from the wall.

Step 3: Remove the Bottom Track

For the bottom track, make the same cuts in Step 2 to loosen the jamb from the caulk. For the side jambs, make one cut for the outside of the track and one cut for the inside. Use a putty knife and hammer to slice away the caulk. Remove the bottom track and place it to the side.

Step 4: Scrape Away the Excess Caulk

Wearing rubber gloves, scrape away any caulk residue left on the side walls and the tub's ledge. Make sure the area is thoroughly cleaned before proceeding with the installation of the shower door.

Tip: As the project proceeds, there are a number of parts to keep in order. Painter's tape can help organize all the small pieces; separate the parts for each side of the door and place each section of parts on a strip of tape. When needed, each piece is easily found, and due to the low-tack feature of the tape, the parts will be free of any sticky residue.

Step 5: Secure the Bottom Track

Take the bottom track and, with the outer lip facing away from the inside of the shower, lay it on the ledge of the tub. To accommodate the side jambs, leave a 3/4" gap between the bottom track and the edge of each shower wall. Temporarily secure the bottom track with painter's tape before lightly marking the track's position with a pencil.
