glass shower door installation

Glass shower doors look elegant and classy when installed in a bathroom. Trade in your old shower curtains for this sleek and modern upgrade. Made of tempered glass, glass shower doors are easy to clean, as well as durable. Adding a glass shower door to your space can also make your bathroom appear bigger because of its transparency. There are generally two types of glass doors—frameless and framed. Frameless enclosures are much more challenging to install, while a framed door is generally more straightforward to install. In either case, it’s recommended that you hire a professional for glass shower door installation. Read on to learn more about the overall process.

Many tools are needed for the installation. They include:

  • Pencil
  • Fills
  • Measuring tape
  • Screwdriver
  • Drill bits
  • Caulking gun
  • Hammer
  • Hole saw
  • Electric screwdriver
  • Screws
  • Clear silicone
  • Electric drill
  • Sand cloth
  • Scissors
  • Level
  • Slip-joint pliers
  • Hack saw


Measurements are a key step in the installation process. First, determine the position of the door. With your measuring tape, measure the height and width of the walls. These figures are used to determine the appropriate size of the glass door you’ll be using, so it’s important to note the exact measurements for later.

Select a Product

Choose the glass door according to your design preference, but bear in mind the measurements you’ve taken. Fortunately, glass shops usually have many available options. You can choose a door that’s frameless or framed. You can also choose between a bypass or hinged door. Hinged doors are like other standard doors that open from both sides. Bypass doors often slide. Also consider the door handle and the glass type, either textured or clear. Make sure that glass is tempered to prevent cracks and shatters, which are dangerous.

For classic sliding doors, start by placing the two rails on the horizontal walls over your shower and tub. Be sure to take measurements first. Measure the distance between the two rails and adjust if necessary. You may need to cut the rails with a hacksaw because some walls are uneven. Keep the rubber inside for safety, then file the edges with sandpaper for smooth edges.

After filing, put the rubber back and cut off any excess. The bottom rail will be positioned in between the two walls. The sidewalls are tightened with a tape. A good idea is to center the bottom rail on the center of a bath curb. Make sure that all rails are leveled.

Use your caulk gun to apply silicone caulk to the bottom rail. Attach this to the bath curb.

The distance of the horizontal rails on the top is also measured. You can cut the rail if it’s too long. Usually, 4 mm is cut shorter for an easy fit. You can file the edges for smoothness and precise fitting.

The upper rail will slide down onto the two horizontal wall rails. Drill from inside and outside of the rails. You can now attach the rails with the screws.

Place rollers and install the handle as per the manufacturer’s instructions.

Hang Door

Carefully hang the door from the upper rail. The grooves should align with the rollers. A click is heard once it is perfectly placed. A guide should be inserted on the bottom rail. These are usually included with the door. This is placed under the glass door. Drill and screw from the glass door set for fixation. The clear silicone is placed on the outside and inside of the shower door frames. Remove excess for a smooth finish. Wait for at least 1-2 days for the silicone to dry.
