Description
Threshold-free, level-access showers live or die at the step transition, and these pre-formed step corner seals waterproof exactly that point. Shaped to wrap the change in level where the shower floor meets the surrounding build-up, they give a clean, reliable seal that hand-cut membrane cannot match.
They are supplied to suit different step heights, with 20mm, 25mm, 28mm and 35mm options, and in left and right versions so you can detail both sides of the entry correctly. The fleece-laminated material bonds strongly to the waterproofing system, over a flexible, waterproof core built for long-term performance.
