Looking for the right 8–10mm shower door bottom seal?
You’re in the right place.
At SIMBA, we’ve tested our seals for over 30,000 uses — built to last up to 5 years without leaks or cracks.

What is 30,000 used? Tested under normal room temperature, each seal was opened and closed 30,000 times to simulate frequent daily use — proving its durability and long-lasting performance. |
Whether you need an 8mm curved, 8mm, or 10mm bottom seal, we’ve got a perfect fit for every gap size.
Below, you’ll find our top picks — arranged from smallest to widest gap, so you can choose the one that fits your shower best.
