Collection: Curved Shower Screen Seals

Find replacement curved shower screen seals for quadrant shower enclosures, P-shaped bath screens and curved glass shower doors. These curved seals are designed to reduce tension on the U-channel when fitted to rounded glass, which helps lower the risk of the seal lifting at the ends compared with forcing a standard straight seal onto a curve.

Choose by two measurements: glass thickness and bottom gap. Measure the glass itself first, then measure the space between the bottom of the glass and the shower tray or bath rim.

How to Choose the Right Curved Shower Screen Seal

1. Measure glass thickness

Most UK curved shower screens use 4mm, 5mm, 6mm, 8mm or 10mm glass. Measure the glass itself, not the old seal.

2. Check the gap

Measure the vertical gap between the bottom of the curved glass and the tray or bath rim.

3. Pick the closest fin size

Choose the closest fin size, such as 12mm, 16mm, 20mm or 23mm, then compare the old profile with the product images.

Why Buy Your Curved Seal from SIMBA?

Curved shower screen seals can look very similar, but if the glass thickness, bottom gap, fin length or manufactured curve does not match, the seal may be difficult to fit, lift at the ends or still allow water to escape.

Each SIMBA curved seal is listed by glass thickness, bottom gap and fin size, with clear product images, profile diagrams and videos to help you check the shape, flexibility and bending performance before ordering.

  • Curved-specific profiles, not standard straight seals forced onto curved glass
  • Clear size matching by glass thickness, bottom gap and fin size
  • Product videos to check flexibility, profile shape and finish
  • Send us a photo and measurements before ordering if unsure
  • Cut to size at home; unused and uncut seals can be returned under our returns policy

A cheaper universal seal may cost less upfront, but the right curved profile can help reduce repeat orders and refitting.

Curved Shower Screen Seal FAQ

Common questions about choosing, fitting and maintaining curved shower screen seals for quadrant enclosures, P-shaped bath screens and curved glass shower doors.

1. Can I use a straight seal on curved glass?

We do not recommend it. A straight seal is not shaped to follow curved glass, so it may kink, lift or come loose even if the glass thickness is correct.

For quadrant enclosures, curved shower doors and P-shaped bath screens, choose a curved shower screen seal instead. For the full explanation, read why straight shower door seals don’t work on curved glass doors .

2. Why does my curved shower seal lift at the ends?

The seal may be under tension, or the curve may not match the glass closely enough. If the U-channel is too tight, too loose or too rigid, the ends can lift after fitting.

A properly curved shower screen seal should sit naturally around the glass with less spring-back.

3. How do I fit a curved shower screen seal?

Most curved shower screen seals are fitted by removing the old seal, cleaning the glass edge, pressing the new curved seal onto the glass from one end, then trimming any excess after fitting.

For the full step-by-step guide, read how to fit a curved shower screen seal .

4. Do P-shaped bath screens need a specific seal?

Often, yes. A P-shaped bath screen usually has curved glass and sits above a bath rim, so the seal needs to match the curve, glass thickness and bottom gap.

Choose a curved shower screen seal with the correct fin size rather than relying only on the old seal shape.

5. What if water still leaks near the hinge or corner?

If the seal fits correctly but water escapes near the hinge or corner, the issue may be a small corner gap rather than the bottom seal itself.
