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.
1) Remove 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.
2) Assess sweep dimensions
Measure the glass door thickness and the length needed for a replacement.
3) Assess 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.
4) Cut 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.
5) Insert 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.

Shower Door Cleaning
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.
- 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.
