Any drop that will pass over the bracket should be fine if it is on the inside edge. This is because the water will be kicked inward, away from the edge of the tub, when the door closes.
To determine if a 1/4" overhang is enough, consider the door's opening direction. The sweep needs to be short enough to not get caught on the metal flange when it closes.
A 1/4" overhang should be more than enough to kick the water off the door inward, away from the edge of the tub. This is because splashes would have to go up, under the 1/4" sweep at exactly the right angle to go directly over the 3/4" angle on the outside.
You can test this out by cutting the duck-tape down to 1/4" and showering for a week or two to see how little water actually escapes.

Choosing the Right Replacement
You'll want to consider the type of shower door you have, as this will determine which replacement part you need. If your door closes against glass, you'll need a different seal than if it closes against a wall.
There are three main types of replacement parts: the bottom seal, side sweep, and door jamb. The bottom seal or bottom sweep runs along the bottom of your door, while the side sweep or acrylic seal prevents water from escaping through the hinge side of the door. The door jamb or door stop goes along the side of the door that opens and keeps the door from swinging inward.
To ensure you get the right replacement, you'll 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”.

Installing the New Sweep
Installing the new sweep is a straightforward process. Just make sure to align the holes in the sweep with the holes in the door.
Depending on the type of sweep, you'll either snap it onto the bottom of the door or slide it into place.
If it's a screw-on type, secure it with screws. The sweep should create a tight seal against the floor or shower threshold.
If the sweep feels too tight, try rubbing a little dish soap along the edge of the door. It'll help the sweep slide on more easily.
