How to Replace a Shower Door Threshold How to Replace a Shower Door Threshold
When you have to replace a shower door you might as well replace the shower door threshold. Over the life of the shower the shower door threshold can become worn out and even covered in mold or rotting grout. The shower door threshold is a rubber strip that curbs around the shower. The shower door threshold is adhered to the shower itself and is used to push water back into the shower to prevent water from hitting the floor. This works much better if a shower door wipe is also installed. The shower door threshold is easily removed and replaced and the following article will show you how.
Step 1 – Remove the Shower Door
When removing the shower door threshold you may need to remove the shower door. This depends on the specific door. You'll be able to tell by opening the door. Inspect the floor where the door is for a rubber strip. If there is one you can skip to Step 2. The shower door threshold may also be on the bottom of the door. It will be a piece of rubber as it would be if in the floor. Removing it with the shower door still attached may prove difficult. Remove the door by removing the screws at the corner where it swings. Be very careful so the door does not fall away. Once it's off the hinges place it on top of a bed or on towels.
Step 2 – Remove the Shower Door Threshold
Removing the rubber threshold is not that difficult of a job but it can take some time to do depending on if the adhesive is still good. Use the putty knife and wedge it between the outside edge of the shower door threshold and installation site, be it the door itself or the floor. Slide the blade of the putty knife along the strip to break the adhesive bond. Apply leverage and this will allow the rubber to pop free. You can then grab the rubber and pull up on it to remove it. This may cause the shower door threshold to break, which is fine since you are replacing it.
Step 3 – Clean the Site
With the rubber removed you may find bits of it still in the site or on the door, and also remnants of adhesive. Mix equal parts vinegar and water and spray the area down generously with it. This will not only help to loosen the bond between the adhesive and the material but also kill mildew. Use the putty knife to scrape the remaining adhesive away, then follow with a scrub brush to remove residue. Use a towel to dry the site.
Step 4 – Install the Shower Door Threshold
Load the caulking gun with the silicone caulk and apply a bead inside the site or along the bottom of the door. Place the new shower door threshold in place and press down. Wait an hour before using the shower or replacing the door.
