43% of UK frameless shower doors leaks — not because of poor glass, but failed seals.
Frameless glass shower doors look stunning — clean, minimalist, modern.
But the very design that makes them stylish also makes them more demanding when it comes to installation and sealing.
At SIMBA, we’ve been designing and manufacturing shower door seals for over 20 years.
We supply seals to frameless shower brands across the UK and Europe.
So… do frameless shower doors leak?
In this guide, we’ll take a closer look at why frameless shower doors are prone to leaking, where leaks typically occur, and how you can fix them without tearing out your entire shower setup.
Why Do Frameless Shower Doors Leak?
Many people assume that frameless shower doors leak due to damaged glass or poor installation, but the real culprit is often the seal.
Frameless doors lack the bulky frame and rubber trims of traditional shower doors, leaving only the seals as the primary barrier to water leakage.
Common leak points include: the bottom, hinges, corners, and sliding door edges.
Leaking frameless shower doors don't always mean you need to replace the glass.
With the right shower door seals and simple fixes, you can avoid expensive repairs.
In the next sections, we'll dive deeper into why leaks occur at these points and provide straightforward solutions to fix them.

How to Stop Frameless Sliding Shower Door Leaks at the Bottom
Most of the time, bottom leaks on frameless sliding shower doors are caused by one simple thing — no bottom seal.
Take a quick look:
Is there a clear plastic strip running along the bottom edge of your shower door?
If not, that’s the problem.
No worries — you can easily get one from SIMBA.
We recommend the seal that solves frameless sliding shower door leaks at bottom:
This type of seal is commonly used on sliding shower doors, both framed and unframed, and it fits perfectly.

Already have a bottom seal, but still leaking?
Then it might be time to add a clear threshold seal — a small strip that goes on the shower tray to block water from escaping underneath.
Don’t Seal It with Silicone
When faced with bottom leaks, many people think:
“Can I seal the gap with silicone?”
We strongly advise against it, for a few reasons:
- Silicone discolours and turns black over time
- It’s extremely difficult to remove later
(One customer told us it took over 3 hours to scrape off the old silicone!)
