How to Replace a Frameless Shower Door Seal

The plastic seal on the bottom of a hinged and pivoting  frameless glass shower door will eventually develop tears and cracks from opening and closing the door.

The video instructions cover every step needed to remove, find a replacement part, and how to replace a shower door seal to retain sealing effectiveness.

Frequently Asked Questions

The bottom door seal – aka door sweep or door wipe – of a hinged frameless shower door keeps water in when the door is closed, and wipes water into the shower when the door is opened.

A damaged shower door seal will leak water

The plastic seal is a wear and tear item that will develop tears and cracks, and when this happens, a complete seal replacement is necessary to retain sealing effectiveness.

The firm, but flexible, sweep channel is slightly narrower than the actual glass thickness, creating a tight pressure-fitted connection. Starting from one end, pull the sweep off the glass door.

Tip 1: Place a soft towel directly under the door and sweep to protect your hands if the sweep suddenly breaks loose; causing your hands to smack the floor.

Tip 2: If excessive mineral build-up is causing difficulty in removing the seal, use a glass scraper or putty knife to scrape away the mineral build-up.

The frameless shower door seal is not attached with adhesive and doesn’t require tools for removal or installation, but a replacement seal may require a tape measure for measuring, and a hacksaw to cut the new sweep to exact length.

Shower door seals vary in style. Use the the door seal that was removed as reference to buy a replacement part.

Find your frameless shower door seal
  • Amazon sells universal door sweeps that should fit any door, but will need to be cut to exact length.
  • DK Hardware is a reseller of C.R. Laurence products and may cut to exact length for a fee. Contact DK Hardware for current cutting options.
  • If the shower door brand and model is known, contact the manufacturer for possible replacement parts – e.g. Kohler Parts – that are a direct fit with no cutting required.

Tip: Ordering multiple sweeps may reduce overall shipping costs, while providing a needed inventory for future replacements and miscuts.

A hacksaw with a 32-TPI blade, combined with a basic miter box, is a simple solution to make an even and hassle-free cut. Then use a utility knife to deburr after cutting.

How to cut a shower door sweep

A few other cutting methods were tested, but not recommended:

  • A ratcheting PVC tubing cutter or pruning shear may work, but results were inconsistent.
  • Using a utility snip or scissors will crack the rigid PVC material and yield in an uneven cut.

Use the same removal, replacement, and glass cleaning steps provided in the instructional video to clean soap scum and mineral build-up on and around the sweep between full seal replacements.

  • To clean the glass, use any general purpose bathroom spray cleaner or glass cleaner. A non-scratch scrub pad works well when a cleaning cloth doesn’t.
  • Use a glass razor scraper, combined with general purpose bathroom spray cleaner or glass cleaner to remove hardened mineral build-up on the glass door.
  • To clean an existing door sweep, use a grout brush or a non-scratch scrub pad.
Items to clean the area of a shower door sweep
  • If a drip edge is part of the shower door sweep, face it inwards to keep water within the shower.
  • Point the shower head away from the shower door and corner pivot joints.
  • Use a bath mat to absorb any water that may escape the shower stall.
  • Inspect caulk joints regularly for deterioration.
