Instructions for Replacing a Glass Shower Door Sweep

Updated

on

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

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.

Doors do vary in thickness. Measure carefully and accurately.

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.

TIP: Ordering extra lengths of sweeps will save on long-term shipping costs, while providing a needed inventory for future replacements and miscuts.

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.

Additional Tips

  • 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.

    THE REPLACEMENT SWEEP I PURCHASED DO NOT FIT INTO THE GROVES AT THE BOTTOM OF THE SHOWERHEAD DOOR. I PURCHASED TWO DIFFFERENT TYPES BUT BOTH SWEEPS ARE A VERY SMALL AMOUNT TOO THICK TO FIT INTO THE GROVES OF THE DOOR TO FIT IN TO THE GROVES. I PURCHASED THE DIFFERENT TYPES OF SWEEPS USED ACCORDING TO THE STORES REPRESENTATIVE (PLUMBING). PLEASE ADVISE ON HOW TO FIT THE SWEEP CORRECTLY TO FIT UNDER THE SHOWER HEAD DOOR. THANKS!

      Hi Bryan,
      Do have an existing sweep that was removed from your shower door as a benchmark? When you say “grooves on the shower door”, I’m assuming your door is different than the swinging style shown in the article and video? Do you have a sliding shower door like these versions from DK Hardware?
