The plastic seal on the bottom of a shower door, known as a sweep, will develop tears and cracks from opening and closing the door, and eventually needs replacing.
Our shower door seal replacement video instructions cover step-by-step on how to remove the bottom shower door sweep, find a shower door sweep replacement part, and how to install a new shower door seal.
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.
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 frameless shower door seal is not attached with adhesive and doesn’t require tools for removal or installation. The firm, but flexible, sweep channel is slightly narrower than the actual glass shower door thickness, creating a tight pressure-fitted connection. To remove, start at one end of the shower door and pull the seal down, and off, of the shower door.
Place a soft towel directly under the door and sweep to protect your hands from smacking the floor if the sweep suddenly breaks loose.
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.
Amazon has a diverse selection of suppliers and types of shower door seals.
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.
Shower door seals vary in style. Use the the door seal that was removed as reference to buy a replacement part.
Tip: Ordering multiple sweeps may reduce overall shipping costs, while providing a needed inventory for future replacements and miscuts.
A replacement seal may require a tape measure for measuring.
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 (ref. video instructions).
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 the plastic door seal and groove, use a grout brush, non-scratch scrub pad, or both.
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.
