Glass shower doors are a perfect completion to a tiled shower enclosure, offering a more attractive and effective water containment than a traditional shower curtain and rod. Glass doors can be clear or frosted for privacy, and there is a range of track finishes to match almost any bathroom decor.
Clean the tile surface with a household cleaner to remove any film or dirt from the tub ledge and tile surfaces where the frame of the shower door is to be installed.
Measure the inside width of the shower at the top surface of the tub ledge, from wall to wall. Mark this dimension on the bottom track piece of the shower door frame.
Use a hacksaw to cut the bottom track piece to the length determined in Step 2. Use a metal file to smooth any rough edges from the cut. Also use the file to ease the lower corners at the ends, if necessary to allow the track piece to fit firmly flat on top of the tub ledge. Important: Make certain the deeper door channels are facing up before marking and making any modification to the track corners.
Place the bottom track piece on top of the tub ledge, centering it on the flattest portion of the ledge surface. Measure the distance to the edge of the tub ledge to confirm the track is centered, then use masking tape to temporarily secure the track in position. Tape both ends, the middle and along the track as needed to hold it firmly in place. Use a soft-lead pencil to draw a line along the front edge of the track on the tub ledge.
Position the right-side vertical frame piece against the right wall, slipping the lower end into the bottom track. Make certain the side-frame piece fits down fully into the bottom track. Use a metal file to ease the lower corners of the track slightly, if necessary to get a tight fit into the lower corner where the tub ledge and the wall tile meet.
Use a level to hold the frame piece plumb. Mark the screw holes in the track on the tile surface with a pencil. Set the vertical track piece aside.
Repeat Steps 5 and 6 for the left-side vertical side frame piece.
Center-punch the screw hole locations marked in Steps 6 and 7, using a hammer and a nail set. It is only necessary to nick the tile glazing slightly as a pilot point for the holes.
Use an electric drill with a 3/16-inch masonry or tile-cutting bit to slowly drill out each screw hole. Surface chipping can be minimized by placing a small piece of masking tape over the mark before drilling. After drilling the hole, use a hammer to tap plastic screw anchors into each hole.
Remove the tape holding the bottom track in place. Turn the track over and run a 1/2-inch bead of silicone caulk in its front and rear channels. Keep the bead slightly higher than the depth of the channel flanges.
Place the bottom track in position, aligned with the pencil lines marked in Step 4, and press it down flat on the tub ledge surface.
Run a 1/2-inch bead of silicone caulk in the front and rear channels of the right-side vertical frame piece. Keep the bead slightly higher than the depth of the channel flanges.
Position the right-side vertical frame piece in place, inserting the lower end into the bottom track. Make certain not to move the lower track out of alignment with the pencil lines you made on the tub ledge. Align the side track with the screw anchors installed in Step 9. Use a Phillips screwdriver to insert the screws provided with the track into each anchor location. Tighten them until the track is held firmly against the tile wall surface.
Repeat Steps 12 and 13 for the left-side vertical door frame.
Measure the inside width of the shower at the top of the two vertical door frame pieces, from wall to wall. Mark this dimension on the top door track piece of the shower door frame.
Use a hacksaw to cut the top track piece to the length determined in Step 2. Use a metal file to smooth any rough edges from the cutting.
Insert the top door track piece into position. Secure to the vertical side track pieces with the screws provided, inserting the screws through the predrilled holes at both ends of the track.
Install the inside door by slipping the top of the door panel into the upper inside channel, then swinging the bottom of the door panel into the lower inside track. Position the inside door panel against the vertical wall frame nearest the showerhead. Install the plastic panel guide into the bottom track, just behind the inside vertical edge of the door. Secure the guide in place with the screws provided.
Repeat Step 18 to install the outer shower door panel into the outer door channel, with the towel bar/handle facing outward.
Install the door bumpers in the vertical track channels by snapping the bumper tabs into the predrilled holes in the channels.
Apply a 1/8-inch bead of silicone caulk around the outside and inside of the door frame where the frame meets the tile and tub ledge surface. Allow the caulk to cure for a minimum of 24 hours before exposing it to moisture.
