Installing a Bypass Shower Door

newport-bypass

Bypass shower doors have glass panels that slide back and forth on a track rather than swinging in or out. In most cases, installing a bypass shower door is a project many homeowners who are handy with common household tools can do themselves. Some bypass doors are designed for shower enclosures, while others are designed for bathtub enclosures. Instructions for installing a door for both types of enclosures are similar. This project guide will explain how to install a bypass door for a shower enclosure.

• Use a level to determine if your shower’s threshold or tub ledge is level and the walls are square. If the
difference in any width is over ½” between the top and bottom of the enclosure, you may need to contact
the manufacturer for a matching filler strip to make the door square.
• Remember this important rule for measuring:  “Measure twice, cut once”.

WHAT YOU NEED FOR THIS JOB:

TOOLS:

  • 4-foot carpenter’s level
  • Measuring tape
  • Center punch
  • Hammer
  • Screwdriver
  • Drill
  • 1/8” bit / 1/4” masonry bit
  • Vacuum
  • Step ladder

MATERIALS:

  • Shower door kit
  • Safety goggles
  • Drop cloth
  • Wall anchors
  • Masking tape
  • Silicone sealant
  • Glass cleaner
  • Soft cloth

Step 1: Measure & Cut the Bottom Track

Step 1: Measure & Cut the Bottom TrackNOTE: Do not cut the top track at the same time you’re cutting the bottom track. The dimensions may be different. Wait to cut the top track at the appropriate step.1.  Remember this important rule for measuring: “Measure twice, cut
once”.2.  Measure the wall-to-wall length in the center of the tub or shower
enclosure ledge. Subtract the dimension recommended by the
manufacturer.3.  Transfer this measurement to the bottom track.

4.  Carefully cut the bottom track with a hacksaw and miter box to fit
the threshold or ledge.

5.  Smooth the cut ends with a file.

Step 2: Center the Bottom Track

Step 2: Center the Bottom Track1.  Center the track between the front and back of the shower threshold
or tub ledge with an equal gap between the end of the track and
each wall.2.  Use masking tape to hold the track temporarily in place.3.  Mark the location of the track on the threshold with a pencil.

Step 3: Position the Wall Channels

Step 3: Position the Wall Channels1.  Place a wall channel against a wall and rest it on the bottom track,
being careful not to move the track.2.  Place a carpenter’s level against the channel and adjust it until it’s
level.3.  Use a pencil to mark the mounting hole locations on the wall.4.  Repeat this procedure for the wall channel on the opposite wall.

Step 4: Drill Holes for the Wall Channels

Step 4: Drill Holes for the Wall ChannelsDrill at the marked mounting holes.Ceramic tile
1.  Put an X of masking tape over the pencil mark on the tile to keep the
drill bit from wandering over the surface. You should be able to see
your pencil mark beneath the tape.2.  Use a center punch to nick the tile as a starting point for drilling, being
careful not to crack the tile.3.  Use a ¼” masonry drill bit to drill the holes.

4.  Tap wall anchors into the holes with a hammer.

Use a 1/8” drill bit to drill the holes. Wall anchors are not required.

Step 5: Install the Bottom Track

Step 5: Install the Bottom Track1.  Remove the masking tape and bottom track.2.  Clean the shower threshold or tub ledge thoroughly with rubbing
alcohol.3.  Apply a bead of silicone sealant on each wall where the end of the
track will be located.4.  Apply a bead of silicone sealant to the underside of the bottom track.
Use enough sealant to secure the track to the threshold or ledge, but
not so much that the
track doesn’t come in full contact with the surface.

5.  Install the bottom track on the threshold or ledge at the location
marked earlier with the high side of the track towards the outside.

6.  Wipe away any excess sealant.

Step 6: Attach the Wall Channels

Step 6: Attach the Wall Channels1.  Add rubber bumpers to the anchor screws per the manufacturer’s
instructions and screw them into the wall channel.2.  Repeat this process to install the other wall channel.

Step 7: Cut and Install the Top Track

Step 7: Cut and Install the Top Track1.  Measure the wall-to-wall length at the top of the wall channels.
Subtract 1/8”.2.  Mark this measurement on the top track.3.  Carefully cut the top track with a hacksaw4.  Smooth the cut ends with a file.

5.  Install the top track onto the wall channels.

6.  Wipe away any excess sealant.

Step 8: Install Rollers

Step 8: Install RollersInstall the hanging bracket and rollers on the door panels per the
manufacturer’s instructions.

Step 9: Install the Doors

Step 9: Install the DoorsNote: Have someone assist you in lifting and installing the door panels. Always hold the glass by the sides when maneuvering it.1.  Place the bottom of the inner door into the shower, then hang the
rollers on the inside rail of the top track.2.  Slide the inner door towards your showerhead and check to be sure
the door makes full contact with the rubber bumpers. If not, remove
the door and adjust the roller screws until the door is square with the
wall.3.  Install the outer door in the same manner as the inner door.

4.  Slide the outer door away from the showerhead and adjust as
necessary in the same manner as the inner door until square.

Step 10: Install the Center Guide

Step 10: Install the Center Guide1.  Stand inside the tub/shower enclosure and slide both doors to one
side of the enclosure.2.  Slide the center guide to the center of the bottom track.3.  Slide the inner glass door to the opposite side so that the enclosure
is closed.4.  Position the center guide evenly between the inner and outer doors.

5.  Mark the mounting holes for the center guide on the bottom track
frame.

6.  Use a 3/32” or manufacturer-specified bit to drill the mounting holes
into the bottom track.

7.  Attach the center guide to the bottom track, being careful not to over
tighten.

Step 11: Finish Your Project

Step 11: Finish Your ProjectNote: Allow the silicone to dry for 24 hours before using your shower.1.  Apply silicone sealant to both ends of the bottom track where it meets
the wall channels and along the inside seam of the bottom track and
wall channels.2.  Install handles or towel bars.3.  Clean the glass doors with glass cleaner and a soft cloth.
