You WILL get wet. Kind of like the splash zone at Sea World. I try to keep the water in the sink, but it's no use.
i'd say that maybe 25% of the time i end up wish a wet spot on the front of my shirt/pants when i do the dishes.
I do wear an apron, but the counter and the floor get splashed. I also have a dishwasher, but sometimes I have do do some handwashing.
