For my sins, I bought and fitted a Victoria Plum bathroom set. Despite the design being anything but standard, and most of the fittings again being anything but bloody standard, I've had constant problems with the shower screen leaking. It's a small 500mm straight shape bath with overhead mixer shower. The shower screen is a one piece glass on a swivel hinge fixed to the wall. The base of thw shower screen is circular. When I fixed the screen in place I used some waterproof/mould proof silicone at the base and down the side and fixed it flush to the bath. However, the sealant strip that was provided and subsequent ones since are all 90 degree square as standard. When fitted to the underside of the screen and butting up against the circular pillar of the shower screen, there is always <1mm gap where they meet, as a result water constantly leaks out and down the side of the bath. I've tried difference seal strips and cutting them more oval to sit more flush on the swivel bar, but with no real luck. Other than replacing the screen for one that has a fixed section and then a swivel section, is there anything else I can do?
