* Stand closer to the urinal . . . about six inches away from it works.
** Never aim at the water . . . if there is any, or if you're using a bowl.
*** Try to hit a vertical surface rather than a horizontal one. So aim for the back WALL of the urinal, not the bottom of it.
**** Make your stream hit at an ANGLE, by either aiming downward or off to one side.
And the best way to avoid splash back for WOMEN is to put some toilet paper in the water to soften the impact. This would probably work for us too gents.
