Is it possible for a standing urinal to erode from people unrinating on it constantly similar to landscape changes due to weather? If so, how long would it take before a hole was formed through the urinal?

I've wondered with millions of people possibly urinating all the time especially in high traffic areas (e.g. restaurants, airports etc..) would the urinal be urinated in enough to the point where the urinal would no longer serve to be useful and if so how long would that take?

Fired ceramic is extremely durable; we're talking thousands of years...thus we find pot sherds in the archaeological record that are broken, yet not terribly worn or eroded in other ways. 

Ceramic, especially when glazed, is also significantly acid-resistant. 

So basically, it would have to be peed on pretty continuously for thousands of years for any wear, if any, to be apparent.
