Caret Down

Reliable Side Seal. No Mold. No Mess.

The SIM-0014a vertical shower door seal features a 10mm round bulb fin that effectively seals vertical gaps between 6–9mm.

Designed for use along the side of straight glass doors, this seal blocks water spray while maintaining a clean, modern look.

 ⚠️ Not suitable for bottom installation.
Using it at the base may trap water inside the bulb, increasing the risk of mold or mildew over time.


Fits 8mm thick glass with a secure push-on U-channel design — no glue or tape needed.

Trim to size at home – available in standard lengths.

Key Information About Shower Door Seals

Great question!

Each SIMBA seal is made for a specific gap.

If the gap’s too small, the fin bends and wears out faster.

If it’s too wide, water can leak.

We test every seal to make sure it fits perfectly

Please check out our guides:

“All type of shower door seal replacement”

Many people make common mistakes when using them.

We’ve listed them all – check out “Mind the Gap: 11 Common Shower Door Seal Slip-Ups” so you can avoid them.

In that case, an adhesive bath seal is a better fit.

It’s easier to apply in tight spaces and still gives great protection.

Yes, we have a detailed guide to cutting shower seals.

All SIMBA products come with a 30-day return policy and a 10-month warranty.

If you’re not satisfied, we’ll give you a refund.

If you are unsure about the suitability of a product, we strongly recommend that you order a sample, as the cost of returning a seal is usually higher than the cost of the product itself.

All prices include VAT and standard UK mainland shipping.
