A pivoting glass frameless shower door will have a removable and replaceable door sweep along the bottom. By maintaining this shower door seal, you’ll ensure water doesn’t leak in the areas the seal should be protecting.
You’ll only need a few basic hand tools to cut the new seals to exact length, or for a little extra cost you can buy pre-cut shower seals and need no tools at all.
Step-by-step instructions for replacing a glass shower door seal:
1Remove worn door seal
Frameless door seals are simply pressure fitted. There are no adhesives or mounting hardware holding them on.
- Over time and use the sweep fin will eventually tear from the main frame and lead to leaks.
- Mineral buildup will also create an unsightly discoloration over time as well in the seal location, which may be cleaned to a certain extent.
2Assess sweep dimensions
Measure the glass door thickness and the length needed for a replacement.
3Assess sweep style to order
Based on the existing seal and dimensions calculated in the previous step; determine the proper seal to order as a replacement.
4Cut new seals to length.
- A hacksaw with the proper blade (32TPI) will produce a clean-cut.
- A ratcheting PVC tubing cutter or pruning shear may work, but I’ve had mixed results.
- Using a utility snip or scissors can crack the rigid PVC material and most likely yield in an uneven cut.
5Insert new shower door seal.
- Push new sweep over glass door as original was fitted. If a drip edge is part of the sweep, face it inwards to keep water within the shower stall.

Cleaning a shower door and sweep area.
Clean the door sweep area thoroughly before installing a new sweep. Use the same removal and replacement steps above to do a regular cleaning of the sweep and seal area. Soap scum and minerals can build up over time.
Any general purpose bathroom spray cleaner works well when combined with either a scrub brush (utility brush, tile and grout brush, etc.), or scrub pad.
For excess mineral build-up on the glass door, a glass scraper may be required.
Additional tips to help avoid shower water leaks and damage:
- During very cold climates, the door can shift around and leak even if the seal is in perfect condition.
- Point the shower head away from directly spraying the shower door and corner pivot joints as an added measure to prevent water leakage.
- Use of a bath mat will absorb any water that may escape the shower.
- Inspect and ensure surrounding caulk joints are faultless.
