Since the eskimos used to keep a tub of urine around for when they had to wash their hair, it had to survive being on the ice in an igloo. As the water evaporated (and the ammonia) it would get more and more resistant to freezing as it got more concentrated.

It depends on how concentrated it is and what is dissolved in it. Urine is not one chemical but rather a mixture of metabolic byproducts. Most of urine is mae up of urea which has a melting point of 132.7 °C.

lol.. the salt in urine will raise its melting point, so I'd make a guess at a temp lower than 0 degrees celcius.
