All the caravan flat shower doors I have seen have a gap at the bottom of the door so I think it's a universal fitting and not just related to a Bailey Unicorn. However, the sliding curved shower door maybe different due to slide fixing top and bottom.
yeh, i think most of the " flat " shower doors leak at the bottom, the door opens outwards so water will run off it when it opens anyway, we just lay a towel on the floor and up to the bottom of the door, to soak up the spillage
Our previous van but one had a flat door, and there was a plastic strip attached to the bottom that swiveled when the door opened. It deflected water into the tray
I've got a flat/hinged door on my Lunar, it's got a 'gutter' on inside that stops water going under the door and seems to work well, BUT it depends on how the van is levelled as to whether the 'gutter' holds water and drains it onto floor when the door is opened (opens outward)!
I use a shower mat outside the shower cubical and that deals with any draining from the 'gutter'. I'm fortunate in having a large domestic sized shower cubical, so plenty of room to towel off the worst of my 'wetness' before stepping out of the shower, so water splashes/drips on floor are minimal in the bathroom.
