I'm not very tall, only ~184cm. Yet the older I get the more I hit my head on things and the more the world seems designed for shorter people.
Down and toward the rear wall of the urinal. Create a waterfall and not a fountain... lol
I agree this is the strategy that works most often. However, urinals come in different sizes and shapes. They are also mounted at random heights, with the average getting lower over the years. The "sweet spot" is different with each one.
This is actually my favorite design:
Second is any sunken into the floor, like this:
Now that I think about it, I don't think I've ever had any backsplash from a waterless urinal..... If the world were actually concerned with water conservation, all the time and energy spent on making washers and dishwashers more 'efficient' would be spent on requiring all new construction to have waterless urinals in the bathrooms... in residences as well.
Weirdest (and coolest) urinal ever encountered: I was at a pub in Copenhagen and walked into the men's room. One wall was missing. The men's room opened up to a rock garden full of plants and a skylight above. There were no urinals. I walked back to the door, opened it and re-read the sign: 'Herrn' so I was definitely NOT in the women's room. I'm in the stall, taking a leak when I hear a bunch of guys walk in and start pissing. They were not in any stalls! I walk out of the stall to find 3 guys pissing into the rock garden. THAT was the urinal! Pretty cool, IMO.
