Which Shower Door Seal Do I Need?
The right seal depends on two things: where the water is getting out and how thick your glass is. Find the leak in the table below, then match the thickness.
| Where it leaks | Seal you need | |
|---|---|---|
| Under the door | A bottom sweep or bottom wipe with drip rail that pressure fits onto the bottom edge of the glass | Shop → |
| Where the door closes into a glass panel (straight line) | A 180° H-jamb or Y-jamb on the panel edge | Shop → |
| Where the door closes against a wall | A multi-purpose 'H' wipe on the door edge, or a tape-on bulb seal on the wall | Shop → |
| Along the hinges | A multi-purpose 'H' wipe on the hinge side, or a bulb seal | Shop → |
| At a 90° corner panel | A 90° strike seal | Shop → |
| In a neo-angle (135°) shower | A 135° door jamb or strike jamb seal | Shop → |
| Door closes glass-to-glass and won't stay shut | A pair of magnetic seals | Shop → |
| Bottom of a framed (metal) door | A slide-in vinyl sweep | Shop → |
Then match your glass thickness
Clip-on seals are made for one thickness: 1/4", 5/16", 3/8" or 1/2". Here's how to measure it in about a minute. Tape-on seals (bulb, fin, L, V) are chosen by the gap they close instead.
Check the gap
Each seal lists a suggested gap. With the door closed, measure the space the seal has to fill. Bottom sweeps commonly handle about 7/16"; most door-to-panel jambs are designed for about 3/16".
