Perfectly Curved Seals for Glass Doors
The difference is in the curve.
Most pre curved shower screen seals don’t match the glass, causing twists and gaps.
SIMBA seals are engineered with a precise curve, giving you a smooth, tight fit every time.
FAQ For Curved Shower Door Seal
-
My curved shower door seal keeps popping off at the ends. Why?
Most curved glass has a radius around 800mm. Some brands' seals can't match this precise curve.This causes a constant 'spring back' force at the ends, making them pop off. Simba‘s curved seals are engineered with a specific, tight pre-curve to eliminate that pop-off effect entirely.
-
Do curved shower seals need to be replaced more often than straight ones?
No. Durability should be the same. All our seals (straight and curved) are independently tested to last over 30,000 uses under normal conditions.
-
Will a straight bottom seal work on a curved door if I heat it?
⚠️ Professional Warning (SIMBA Does Not Recommend): While heating a shower straight bottom seal can make PVC temporarily flexible, it permanently damages the material's structural integrity and lifespan. This leads to gaps, reduced sealing pressure, and early cracking. We strongly advise against heating.
-
How do you fix leaks around the bottom metal hardware on a curved shower door?
This leaking usually starts from tiny gaps where the seal meets the metal fittings. Our solution is simple: Install the PV29 threshold strip on the edge of your shower tray or bath. This effectively stops water from pooling near the hinge corner, preventing seepage.
-
Which way round should the curved shower door seal be fitted?
The section with the drip rail should always face towards the inside of the shower door.
-
Do I need a specific seal for a shower screen over a bath?
Our seal for curved shower screen over bath is ideally suited for this specific setup. You simply need to select the right product based on your glass thickness and the gap size.
-
My curved shower seal keeps coming off, how to fix it?
This usually means the seal size doesn't match your glass thickness. A properly fitted seal should withstand a pull force greater than 50 Newtons (N) without detaching.
-
Can I use a straight shower seal on a curved door?
No, this is not advisable. A straight seal won't fit the curve, making installation impossible, and the ends will constantly pop out.
