M22 Shower Dribbles

In our 2010 M22 after every shower there are little puddles of water along the wall outside the shower. This is coming from water running down the walls onto the raised edge of the floor piece and then running over the sides. There isn't really anything to force water to drain into the basin rather than off the edge of the basin onto the bathroom floor.

By chance have you engineered something to address this that I can acquire from the factory?

If not, my plan is to fabricate a piece of plastic about an inch wide and epoxy it to the edge of the shower on either side. I will run it from the floor to top of the the shower. At the point the piece meets the basin ledge I will extend it out about 6". I will install the piece along the basin ledge such that it extends slightly over the edge of the basin forcing any water to drop into the basin rather than running around it onto the floor.
