Shower seals are chosen by position: magnetic pairs where two glass doors close together, U or H seals on a vertical edge against a wall or fixed panel, F seals and bottom sweeps along the floor, and silicone water dams on the floor itself. Order them by glass thickness (6, 8 or 10 mm are standard) and the gap they must close.
