Oh Yes, my son did the peeing in the bathroom trash can too!!! Experimental behavior, boys and their toys, seeing what they can do with it! You are doing right by restricting him from his room/toys by himself. This was most likely not an accident. It'll pass. I told my son that since I obviously couldn't trust him in the bathroom alone, then either myself or his dad would have to accompany him each time he went. He didn't like that one bit and never did it again. Took about 3 times of me finding a wet trash can to relize what was going on. Thankfully, my son is not a good liar!
