DH actually takes a tissue and wipes the rim of the toilet after he uses it. He would never create or tolerate the situation described in the OP. I probably wouldn’t have to say a word to the kid.
If DH would put his dirty dishes into the empty dishwasher instead of the sink, which is literally right next to it, I’d think I’d truly died and gone to heaven. As it is, I count my blessings.
I have daughters so can’t help too much on this one. But I’m thinking if it were my kid, the next time he wanted me to drive him somewhere, I’d tell him we aren’t going anywhere until the area is clean. Every single time.
I can’t imagine being 6’6", but if I had such an issue with my aim, I’d maybe bend my knees a bit in order to shorten the range. That might be worth mentioning if he continues to have issues.
My H and sons are all 6’5" + and we do not have this problem. I’m not sure height has all that much to do with it. I’m not sure installing a taller toilet will solve the problem if a person just doesn’t want to be careful or clean up after themselves.
H sits, (not sure why–he never like using urinals?) so our oldest son sat, too. When S#1 went to pre-school, the teacher told me (the mom), “You need to teach your son to pee standing up.” I wasn’t quite sure how to do this, but 20some years later I have 3 adult sons who pee standing up–and I can tell when they’re in the house. Anyway, maybe people are joking about sitting, but it seems like the easiest/no cost/no work solution.
H has always sat. I don’t know why, but I’m grateful. During toilet training, S1 and S2 stood up. Someplace along the way, they morphed into sitting too. Again, grateful. To their wives: You’re welcome!
I gave up somewhere along the line and designated one bathroom for me it’s not convenient but it’s clean…in my opinion it’s not the aim it’s the lack of a shake at the end. I’ve yelled plenty for years on end - ‘take it and shake it’ before you back away from the toilet. Now what I can’t tolerate in "their bathrooms - H included are the black hand marks on the wall above the toilet where they hold themselves so they achieve a position where the aim is not the issue. Good heavens i can’t believe we’re having this “conversation.”
Urination is not the only issue that 15/16 year old boys have that keep them in the bathroom. A little discussion about all the changes his body is going through, and the way to meet those needs such that what happens during his bathroom time is known only to him -and not to everyone else who enters the bathroom - may be in order.
Keep two rolls of paper towels in the bathroom closet/under cabinetry, a little mixture of half cleanser/half water in a spray bottle and strict instructions not to throw the paper towels into the flip-lid garbage can, and, voila, you may have solved your problem.
