Thanks for your interest. I am doing full body massages with fresh urine. I sit on a bath stool in the bath with the shower curtain around and just massage it into all the areas I can reach, the middle of the back does not get done.
I have been using fresh urine, but tomorrow I will start on 4 day old urine. I just hope the smell of it is not too overpowering, I wash everything down with the shower rose so it has not been a problem to now.
I do not use distilled water, our tap water in Melbourne Australia is very good although it does contain chlorine and flouride.
