Over Bath Shower Screen Seals

Our over bath shower screen seals are replacement strips commonly used on bath screens and frameless shower screens fitted above a bathtub. They help reduce water leaking between the bottom of the glass and the bath edge.

Many of these seals are multi-use and may also fit frameless, pivot or sliding shower doors. To find the right fit for your screen, choose by glass thickness, gap coverage and seal profile.

FAQs About Over Bath Shower Screen Seals

For most over bath shower screens, you will need a push-on bottom seal fitted along the lower edge of the glass.

Measure the glass thickness, then measure the gap between the bottom of the glass and the bath edge.

Choose a seal that grips the glass securely and has enough fin or drip length to cover the gap.

They can be similar, but the wording describes a different need. An over bath shower screen seal is used on a bath screen fitted above a bathtub, while a bath screen bottom seal refers specifically to the seal along the lower edge of the glass. For most frameless over bath screens, the replacement is usually a bottom push-on seal.

Yes, if the seal fits the glass thickness, gap size and profile of your bath screen. Many shower door bottom seals are multi-use and can also fit frameless bath screens or shower screens fitted over a bath, so the key is to match the measurements rather than the product name alone.

Measure the glass thickness, the length of the screen and the gap between the bottom of the glass and the bath edge. Use these measurements to choose the correct glass thickness and gap coverage.

Many shower screen seals can be trimmed to the right length with sharp heavy-duty scissors or garden secateurs.

Measure the seal before cutting to avoid trimming it too short. For step-by-step instructions, see our guide on how to cut a shower screen seal.

Check whether the seal is split, loose, too short or the wrong size for the gap between the screen and the bath. Replacing the seal with the correct glass thickness and gap coverage can help reduce water leaking onto the bath edge or bathroom floor.
