Choosing the Right Door Sweep
First, you need to determine which type of door sweep you need. There are three types: bottom sweeps, side sweeps, and door jamb sweeps.
Bottom sweeps go on the bottom of your shower doors and prevent water from leaking out. Side sweeps go on the side of the shower door that opens outward. Door jamb sweeps go on the hinged side of the shower door.

To choose the right door sweep, you need to know the thickness of the glass in your shower door. Door sweeps are sold for standard glass thicknesses like 1/4”, 3/8” or 1/2”.
You also need to consider whether your shower door closes against glass or a wall. This will determine which type of seal you need.
Replacing a Door Sweep
Replacing a door sweep is a relatively easy process that you can do on your own without any special tools or skills. You'll need a replacement seal, a utility knife or scissors, and a clean piece of cloth.
To start, open your shower door completely and inspect the seal. Most seal strips are attached to the door without adhesive, so you can simply pull the seal off in the opposite direction. If the seal is stuck due to mineral deposits, you may need to exert more pressure to remove it.
Once you've removed the old seal, clean the glass door surface with a clean piece of cloth and glass cleaner. Then, take the new seal strip and align it along the glass door, making sure the drip edge is facing towards the inside of the shower area. If the seal is too long, use a utility knife or scissors to cut it to size.

Replacing a Seal
Replacing a seal is a crucial step in replacing a door sweep. You'll need to remove the old seal, clean the glass edge of the door, and measure your new seal against the edge of your shower door.
To remove the old seal, simply pull it off, or use a sealant remover or a scraper if it's stuck with adhesive. Make sure to clean the glass edge thoroughly to remove any dirt, mildew, or debris.
When measuring your new seal, mark how long it needs to be and use cutting pliers to cut to size. If your new seal has a drip edge or lip, make sure to install it facing the inside of the shower.
You'll also need to cut notches in the seal to accommodate the hinges and bottom seal of your door. Use a pair of cutting pliers to cut the notches, and discard the small pieces that are in the center of each hinge.

Some shower doors may require a specialized door sweep installation, such as a recessed door sweep, which is designed to fit into a recessed area of the door frame.
Types of Installations by Placement
Shower door sweeps can be installed in various places, each with its own unique characteristics. The most common type of installation is at the bottom of the door.
The bottom sweep extends through the entire bottom width of the door and is installed at the door bottom. It has a drip edge on one side which is fixed towards the inner side of the shower area.
You can install shower door bottom sweeps on framed as well as frameless shower doors with your bare hands. When considering shower door installation, it’s essential to take shower door thickness into account to ensure a proper seal and fit.

Trim Length Over Framed Edge

The sweep's length over the framed shower door bottom edge is crucial for a proper fit. A sweep that's too short, like 1”, can be clamped by the door and metal underneath, making it useless.
To avoid this, you'll want to choose a sweep that's long enough to cover the door's edge. If you're working with a specific door size, like 32”, 36”, or 98”, make sure to get a sweep that matches.
For example, if you have a 32” door, you'll want a sweep that's at least 32” long. This will ensure a snug fit and prevent water from seeping underneath.
Seals
Replacing your shower door seal is a relatively easy task that you can do on your own without any special tools or skills.
You'll need to start by removing the old sweep or seal, which can be done by simply pulling it off if it's attached without adhesive. If it's stuck due to mineral deposits, you may need to exert a bit more pressure.

To prepare the glass edge of the door for the new seal, clean it with a glass-safe scraper and a soft cloth, and wipe it dry.
When measuring your new seal, make sure to mark how long it needs to be and cut it to size using cutting pliers. The side with the drip edge or lip should be installed facing the inside of the shower.
To install the new seal, simply snap it onto the bottom of the door and slide it into place.
Regular cleaning of your shower door seals can help them last longer. Clean them whenever you clean your bathroom to remove any lingering moisture and mildew.
Avoid using harsh cleaners, as they can cause the seals to deteriorate more quickly.
Here are some common tools you may need to replace your shower door seal:
- Replacement/new shower seals
- Utility knife or scissors
