Our 233S had an issue with water escaping from the shower enclosure around the edges of the shower curtain. Even when we took exceptional care to ensure we kept water IN the shower, we'd inevitably find a puddle behind the toilet when our showers were done. I added a few plastic pieces to both edges where the shower curtain meets the wall. Hopefully this will solve the problem.
The towel hook is nothing exceptional or ingenious, but we just put it on the door so I thought I'd include it.
