Water leaking from the gap at bottom of shower door? Don’t rush to replace it — there’s a smarter fix.
Ever had this moment?
You step out of the shower, and—bam—cold water right under your feet.
You look down, and yep... it's leaked. Again.
You might blame the drain. Or think you didn’t close the door properly.
But the real culprit is hiding in plain sight:
That little gap at the bottom of your shower door.
Yep, the one that “looks fine.”
It may seem tiny, but water loves to sneak right through — quietly dripping its way across your bathroom floor.
Why Is There a Gap at the Bottom of My Shower Door?
We’re not builders — but we’ve seen thousands of “leaky shower scenes.”
And trust us: that gap at the bottom of your door?
It’s not just your bathroom.
In fact, it’s a pretty standard feature in lots of shower door designs — especially frameless glass doors, sliding doors, and shower screens.
Why? Well, the reasons might leave you raising an eyebrow:
-
To help the door swing smoothly: If it were sealed tight to the floor, it wouldn’t open properly.
-
Ventilation, apparently: Some designers claim that a little airflow helps keep the space dry.
-
Tiny installation errors: Even with the best tools, it’s tough to get every wall, panel, and tray lined up to the millimetre.
-
Shower trays can shift over time: Yep, even a few millimetres of settling can turn a “tight fit” into a puddle zone.
No matter the reason, the outcome’s the same: soggy floor, annoyed you.
So no — it’s not just your shower door bottom that leaks.
But that doesn’t mean you have to put up with it.
No Glue, No Bricks, No Plumber Needed — Just One Little Plastic Strip Does the Job
We’ve always believed:
Good design isn’t complicated. It’s so simple you think, “Oh, that’s all it takes!”
That’s why we use a clear, pre-cut SIMBA shower door seal, paired with a subtle threshold strip. Stick them on gently, and that pesky gap? Gone.
It’s like putting an invisible raincoat on your shower door — water can’t sneak out, and you don’t have to stress.
Two Easy Steps to Say Goodbye to Bathroom Floods
Step 1: Fit the Bottom Shower Door Seal
This soft PVC strip is cut to fit your glass thickness (from 4mm to 12mm — we’ve got you covered).
-
📎 No glue, no screws — just slide it on.
-
📎 Heat resistant and transparent, almost invisible.

Or just get in touch — we’re happy to help you pick the right one.
Step 2: Add a Clear Threshold Seal to Your Shower Tray
Think of it as a tiny ramp stuck right at the base of your shower door.
Water hits it, then obediently turns back towards the drain — no more escaping mess.
We strongly recommend adding this extra line of defence to frameless shower doors or screens with bottom gaps.
