So will you pee in your sink ?

Human urine is loaded with nitrates , great for the plants and every time you use the loo you flush down 5-10 liters of clean drinking water to flush it away. Now for an entirely hypothetical solution. Say your spouse is averse to not flushing the loo after every use and equally averse to bottles of pee in the loo and you have a greywater system connected to the bath sink that goes to the plants outside, would you let all of these nitrates go waste along with fresh potable water or would you pee in your sink ?
