Not all frameless shower door bottom seals are the same.
At SIMBA, we’ve spent over 25 years perfecting our shower door sweep with drip rail — built to last, easy to fit, and made to keep your bathroom dry and spotless.
In this quick guide, we’ll show you how to choose the right shower door sweep with drip rail and how to tell if a drip rail is truly durable — so you don’t have to replace it again anytime soon.
What Is a Shower Door Sweep with Drip Rail?
You might not have heard the term shower door drip rail before — it’s simply the seal that fits along the bottom edge of your shower door, but with one clever extra feature: a drip rail.
It’s the small ridge or lip (the red-marked part in the image below) that directs water back into your frameless shower tray instead of letting it run onto the floor.
This plastic might look like a tiny detail, but it makes a big difference — especially in the UK, where the damp weather can quickly turn a minor leak into peeling paint or even water damage on the ceiling downstairs.
How to Choose the Right shower door drip rail at SIMBA
We’ve made it super easy to find the perfect fit.
Just check your glass thickness and gap size, then click the matching model below to order.
All our shower door drip rails are designed for frameless shower doors — built to stop leaks and tested to last over 30,000 uses.
Plus, every SIMBA seal is made with an anti-mould formula to keep it clean, fresh, and long-lasting.
| Glass Thickness | Gap Size | Length | Model |
|---|---|---|---|
| 4–6mm | 9–12mm | 950mm | V456S12 |
| 4–6mm | 13–16mm | 950mm | V456S16 |
| 4–6mm | 17–20mm | 950mm | V456S20 |
| 4–6mm | 20–23mm | 950mm | V456S2023 |
| 8–10mm | 9–12mm | 950mm | V810S12 |
| 8–10mm | 13–16mm | 950mm | V810S16 |
| 8–10mm | 17–20mm | 950mm | V810S20 |
| 8–10mm | 20–23mm | 950mm | V810S2023 |
| 3–20mm | 12–35mm | 950mm | V312S1235H |
Choose your seal based on the actual gap under your shower door.
If the fin is too big for the gap, it’ll get squashed and wear out faster — meaning you’ll have to replace it sooner.
