All our bathroom furniture is built from high-quality materials, constructed to be not only beautiful to look at but functional for everyday life. Usually we get great feedback from our customers to help us there, but every so often we come across a bit of info that we feel helps us to improve and more importantly, educate others. A customer recently contacted me with a simple but prevalent problem:
“The gasket on the bottom of my shower door drags when I open and close the door.”
If you've faced this problem you exactly how irritating it is. Aside from the door feeling like it is sticking, the added resistance could cause premature wear on the gasket and the door mechanism.

What is the Bottom Gasket on a Shower Door?
The bottom gasket (sweep or door seal) is the plastic or rubber strip found at the bottom edge of a glass shower door. It serves several purposes:
- Prevents water from leaking onto the floor
- Softens the impact of door contact with shower threshold
- Retains air drafts and moisture within the enclosure
With time, this gasket can become misaligned, or warped, or simply too tight as it drags against the shower curb or tiles.
Here's Why Your Shower Door Gasket Is Dragging
Some possible explanations include:
| Cause | Description | Fix Difficulty | Tools Needed |
|---|---|---|---|
| Misaligned door | The door has shifted slightly downward or inward. | Moderate | Screwdriver, Level |
| Warped gasket | The material has curled, hardened, or become brittle. | Easy to Medium | Replacement Gasket |
| Incorrect installation | Gasket may be installed too tight or upside-down. | Easy | No tools (just re-fit) |
| Sagging hinges | Continuous use has loosened the hinges over time. | Medium to Hard | Hex wrench, Screwdriver |
| Debris buildup | Soap scum or limescale is blocking the gasket from gliding. | Easy | Vinegar, Sponge |
How to Get Your Gasket to Stop Dragging: A Step-By-Step Guide
Step 1: Inspect the Gasket
- Open the shower door and look where the gasket touches your floor or curb.
- It's a good idea to check for bends, cracking and uneven wear.
- If so, check for the gasket before the bottom edge is even.
Ace Decor Pro Tip: Angle a flashlight underneath the door — if the light is blocked unevenly, the gasket is probably out of alignment or damaged.
Step 2: Clean the Gasket and Threshold
Sometimes the problem is just dirt:
- Combine equal parts white vinegar and warm water in a spray bottle.
- Spray the gasket and threshold.
- Gently scrub with a non-abrasive sponge or soft toothbrush.
- Dry with a microfiber cloth.
Step 3: Realign the Door (If Misaligned)
If the door appears to sag or tilt:
- Use a level to check the alignment of the door.
- If the top corner of the door droops:
- Use a hex key or screwdriver to adjust the top hinge.
- Tighten or loosen hinge screws to raise or level the door.
- Check both hinges for stability.
Step 4: Readjust the Gasket
In case the gasket is too tight or pushed down too low:
- Gently pull the gasket out from the bottom edge (a lot just slide off).
- Check for any warping.
- Put the gasket back into place, ensuring that it flushes with the door and does not protrude too much.
- If it's a push-in type, push it less deep.
Note: Some gaskets feature fins or drip lips, so be sure the correct side is facing inward to channel the water appropriately.
Step 5: Replace the Gasket if Damaged
If the gasket is badly swollen, old and hard, or permanently warped, the best option is to replace the gasket.
How to Replace:
- Depending on the gasket type and your intent of discarding it, gauge its length and thickness.
- Order a replacement (If you purchased your shower from Ace Decor and the gasket is not functioning well, please contact our support team for returns or a better-fit solution).
- Pulling the old gasket out of the groove.
- Scrub the channel the old gasket rested in.
- Place the new gasket into position, making sure it sits evenly and feels not too tight.
