Water on the bathroom floor is a common sign that your seals have worn out. In most cases, shower screen seal replacement is a quick and affordable fix. It can stop leaks and protect your floor, walls and cabinets. This guide explains the signs, the cost factors and how the job is done.
What do shower screen seals do?
Seals are the soft strips of rubber or plastic along the edges of a shower screen. They close the small gaps between the glass, the door and the wall. As a result, water stays inside the shower. There are several common types:
- Bubble seals: a soft, hollow strip that compresses when the door closes.
- Magnetic seals: strips with a built-in magnet that hold a hinged door shut.
- Wipe or fin seals: a thin blade that sits against the glass or the wall.
- Bottom seals: a strip along the base of the door that blocks water at floor level.
Signs you need shower screen seal replacement
Seals do not last forever. Soap, hard water and daily use slowly wear them down. Look for these warning signs:
- Water leaking onto the floor during a shower.
- Visible gaps between the door and the frame.
- Seals that look yellow, stained or covered in black mould.
- Cracked, brittle, flattened or peeling rubber.
- A door that no longer closes firmly or does not latch.
If you notice any of these, a new seal is usually the answer. However, cleaning may help a little first. Our guide on how to clean and care for your glass shower screen shows how to remove mould and soap scum safely.
What affects the cost of shower screen seal replacement?
The price depends on a few simple factors. Because every screen is different, the best way to know the cost is to ask for a quote.
- Type of seal: a magnetic seal usually costs more than a basic bubble seal.
- Length and number of seals: a larger screen with several doors needs more material.
- Availability: older or unusual screens may need a seal matched to the original profile.
- Other repairs: worn hinges or rollers may need attention at the same visit.
In general, new seals cost much less than a new screen. For this reason, they are often the first thing to try. See our guide to shower screen costs in Geelong for more on pricing.
How shower screen seal replacement is done
A trained installer follows a clear process. Here is how it usually works:
- Check the screen. First, we look at the glass, hardware and where the leak happens.
- Identify the seal. Next, we match the type, length and fit to your screen.
- Remove the old seal. We peel or slide it out of its channel.
- Clean the surface. Then we clear away soap scum, silicone and dirt.
- Fit the new seal. We trim it to size and press it into place.
- Test the result. Finally, we run water to confirm the leak has stopped.
Can you do shower screen seal replacement yourself?
Some people replace simple seals at home. It can work if you find the exact matching profile. However, the wrong size will not seal properly. Also, glass is heavy and needs careful handling. If you are unsure, it is safer to book a professional. Our shower screen repairs service covers seals, hinges, handles and rollers.
When a new seal is not enough
Sometimes a leak has another cause. A door that hangs crookedly or rollers that are worn may let water through even with a perfect seal. In that case, read our guide on how to fix a sticking sliding shower door. If the glass is chipped or the frame is badly corroded, see shower screen repair or replacement to decide your next step.

Frequently asked questions
How often should shower screen seals be replaced?
There is no fixed time. Many seals last several years, but hard water, harsh cleaners and heavy use can shorten that. Replace them when they leak, crack or lose their shape.
Why is my shower screen leaking even with new seals?
The door may be misaligned, the hinges or rollers may be worn, or the wrong seal may be fitted. An installer can check each of these.
Can mouldy seals be cleaned instead of replaced?
Light mould can often be cleaned with warm water and mild detergent. If the stain stays or the rubber is cracked, replacement is better.
How long does shower screen seal replacement take?
It is usually a short job. A single seal can often be fitted within a visit, once the correct part is available.
Do you replace seals on frameless screens?
Yes. Frameless and semi-frameless screens both use seals, and they can be replaced. Learn more about the two styles in our guide to frameless vs semi-frameless shower screens.
