How to buy the right shower door replacement sweep?

There are 3 different types of shower seals: 

• The bottom seal or bottom sweep (which runs along the bottom of your door)
• The side sweep (that prevents water from escaping through the hinge side of the door)
• The door jamb or door stop, which goes along the side of the door that opens and keeps the door from swinging inward.

If you’re replacing the door stop, note whether your shower door closes against glass or a wall, as the seal for each type of shower door jamb is different. Whichever type you’re buying, you’ll also 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”.
