We try as much as possible to fit a single piece of glass, this works in many situations. Where we can’t fit a glass long enough (due to a variety of reasons), then you might need a flipper panel to help keep the splashes inside.
As a simple rule of thumb, if we can fit at least an 1000mm long glass, then you won’t need a flipper panel.
For very large bathrooms, we might fit a long glass (1000mm+) with a flipper panel, but not use any end glass (for those situations where the tray is shorter than the length of the room)
